海外TECH	DEV Community	Power of ChatGPT....	https://dev.to/prathmeshjagtap/power-of-chatgpt-ij7	Power of ChatGPT Introduction to ChatGPTChatGPT is a chatbot that can be used to automate the process of online customer support It works by analyzing conversations between customers and agents then using that information to create scripts for future interactions When a new conversation begins ChatGPT automatically identifies keywords in the user s message and uses them as triggers for specific responses For example If someone asks about your shipping policy ChatGPT will automatically trigger an answer about how long it takes before orders are shipped out and if there are any exceptions This means you don t have to manually create individual answers for every possible question or scenario instead you just have one basic script that can be expanded upon with additional information as needed ChatGPT and Human Computer InteractionChatGPT is a revolutionary technology that can change the way we interact with computers It s not just about being able to ask questions and get answers from them but it also allows us to communicate in a more natural way ChatGPT is changing the way we communicate with computers making it easier for people to ask questions and get answers from them This can improve customer service by making it easier for customers to find out information about products or services they want or need before buying them online Using ChatGPT also has other benefits ChatGPT and Natural Language ProcessingChatGPT uses natural language processing to understand the intent of your customer and then it can respond with an appropriate message Natural language processing is a field of computer science that studies how computers can understand human language It s used in many applications including chatbots like ChatGPT Natural language processing has some challenges though It s difficult for computers to understand context because they don t have a common sense like humans do There are many ways people can use words without meaning what they say literally e g sarcasm ChatGPT and Machine LearningChatGPT uses machine learning to improve the chatbot experience for users Machine learning is a type of artificial intelligence that allows computers to learn from data identify patterns and make predictions based on those patterns It s been used in many industries including finance and healthcare but until recently it was not widely available for use by businesses at scale But now that s changing Machine learning has become affordable enough for small companies like ours to take advantage of its benefits without having to hire PhDs or buy expensive hardware software packages from large vendors like Google or IBM which also offer their own versions ChatGPT and AutomationChatGPT is a powerful tool for automating tasks It can be used to Automate customer support requests by automatically responding to common questions and providing helpful information such as FAQs and product manuals This saves time for both agents and customers as well as reducing the number of repetitive questions that need answering Automate data collection from users who have opted in e g surveys This allows you to collect information about your audience in real time without having to manually ask them questions one at a time on each channel or website where they re interacting with your brand a process that would be extremely labor intensive if done manually ChatGPT and SecurityChatGPT can help improve security by Detecting suspicious activity and reporting it to the user For example if a user receives a message that contains an email address or phone number ChatGPT will alert them to this fact and ask whether they want to continue with the conversation If you choose not to continue then ChatGPT will block that person from contacting you again in future conversations Preventing phishing attacks by detecting when someone is trying to impersonate another person in order to get access to sensitive information like passwords or credit card numbers e commerce sites When someone tries this tactic on one of our users websites we send an alert asking them if they would like us call their phone number so we can verify who they are before proceeding any further with the transaction this feature does require both parties consent ChatGPT and PrivacyChatGPT uses a combination of AI and machine learning to analyze user behavior including what they say and how they say it This allows us to provide better customer support by understanding your needs better than ever before However this also means that ChatGPT has access to all of your private conversations with our agents While we take privacy very seriously at ChatGPT we want you to know that there are some important benefits of using our service You can rest assured that no one will ever read your chat transcripts unless you give us permission first We won t use any information from these chats for anything other than providing better customer service for everyone who uses our platform In fact if someone does try accessing them without permission like an ex employee then we ll automatically delete all traces of their activity so there s nothing left behind for anyone else either ChatGPT and the FutureChatGPT is still in its early stages but it s already showing great promise The team at ChatGPT is working hard to develop new features and improve the user experience for both businesses and consumers As more people adopt ChatGPT we expect to see even more applications for this technology emerge from customer service agents being able to handle more inquiries without needing additional staff members or even robots to virtual assistants that can help you find what you re looking for on Amazon or Netflix The biggest challenge facing ChatGPT in the future Convincing everyone else that they need it too But once they do start using it there s no doubt that this technology will have a huge impact on how we interact with computers across all industries and maybe even change our lives forever ConclusionChatGPT is a platform that uses AI to automate the process of online chat It can be used by companies who want to provide their customers with instant responses support and an improved customer experience ChatGPT allows you to Reduce costs by cutting down on staff hours dedicated to answering repetitive questions Increase revenue by providing better service at all times of day or night even when your team is asleep	2023-04-24 15:56:04

海外TECH	Engadget	The best smart speakers for 2023	https://www.engadget.com/best-smart-speakers-151515264.html?src=rss	The best smart speakers for Voice assistants are everywhere now on your phone in your TV possibly even in your kitchen appliances But one of the most common ways that people interact with Siri Alexa and the Google Assistant is through a smart speaker and there are now a wide variety of such devices available at a wide variety of price points There are downsides to having a smart home device that s always listening for a wake word as giving more personal information to Amazon Apple and Google can be a questionable decision That said all these companies have made it easier to manage how your data is used ーyou can opt out of humans reviewing some of your voice queries and it s also less complicated to manage and erase your history with various digital assistants too The good news is that there s never been a better time to get a smart speaker particularly if you re a music fan For all their benefits the original Amazon Echo and Google Home devices did not sound good Sonos on the other hand made great sounding WiFi connected speakers but they lacked any voice controlled smarts That s all changed now Sonos released its own voice assistant in and also supports Alexa on its latest speakers Google and Amazon meanwhile made massive improvements in sound quality with recent speakers Even lower end models like the Echo Dot and Nest Mini sound much better than earlier iterations With the growing popularity of these speakers there are now more options than ever Let s walk through our choices for the best smart speakers at different price points and for different uses Picking an assistantThe first thing most people should do is decide what voice assistant they want to use Google Assistant and Amazon s Alexa are both well supported options that are continually evolving with new features added at a steady clip A few years ago Alexa worked with more smart home devices but at this point basically any smart device worth buying works with both It s mostly a matter of personal preference If you already use Google Assistant on your Android phone it makes sense to stick with that But while Alexa isn t quite as good at answering general knowledge questions it syncs just fine with things like calendars from your Google account And it works with perhaps the widest variety of smart home devices as well If you ve never used Alexa or Google Assistant you can download their apps to your smart phone and spend some time testing them out before buying a speaker If you buy a Sonos device with a microphone you can also use the company s own voice assistant voiced by Giancarlo Esposito It s focused purely on music control so you won t use it to do things like send messages or ask the weather forecast But as a music assistant Sonos Voice Control is generally quite fast and reliable As for Apple you won t be surprised to learn the HomePod and HomePod mini are the only Siri compatible speakers on the market Siri has a reputation for not being as smart as Alexa or Google Assistant but it s totally capable of handling common voice queries like answering questions controlling smart home devices sending messages making calls and playing music Technically Siri and Apple s HomeKit technology doesn t work with as many smart home devices as the competition but it s not hard to find compatible gear And Apple has most definitely improved Siri s capabilities over the last couple years with handy features like and Intercom tool and routines that take advantage of the built in temperature sensor in the HomePod and HomePod Mini Best smart speaker under Amazon Echo DotMost people s entry point into the smart speaker world will not be an expensive device Amazon s fourth generation Echo Dot and Google s Nest Mini are the most obvious places to start for two important reasons One they re cheap Both the Nest Mini and Echo Dost cost Two they re capable Despite the low price these speakers can do virtually the same things as larger and more expensive devices The Google Nest Mini was released in late but Amazon just refreshed the Echo Dot last year The Echo Dot is the best small smart speaker for most people Amazon keeps improving the audio quality across its Echo device line and the Echo Dot is no exception It produces much louder and clearer audio than I d expect from a speaker The Nest Mini doesn t sound bad and it s perfectly fine for listening in the bedroom while getting ready for the day but the Echo Dot is a better all purpose music listening device From a design perspective Amazon broke the mold with the latest Echo Dot Instead of a small puck like the Nest Mini the new Dot is shaped like a little globe It s much bigger than the Nest Mini but that size gives it room for higher end audio components The Dot keeps the handy physical volume buttons and mute switch on top along with a button to activate Alexa s voice control While the Dot doesn t look as sleek as the Nest Mini having physical buttons makes it easier to adjust volume and mute the mic I do wish the Dot had a way to physically pause music on the Nest Mini if you tap the middle of the device the music stops Another benefit the Amazon Echo Dot has over the Google Nest Mini is its mm audio out jack which means you can plug it into other speakers and instantly upgrade the audio quality When you do that you can ask Alexa to stream music and it ll output to whatever speaker you have connected That ll help you get more mileage out of the Dot in the long run The Nest Mini answers with a handy wall mount for people who want to keep their counter or shelf clear The Echo Dot s new bulbous form is definitely not suited to this so if you want a speaker you can really hide the Nest Mini is probably the better choice Overall the Dot is the best choice for most people but I wouldn t hesitate to recommend the Nest Mini either I generally prefer using Google Assistant over Alexa and anyone who feels the same should go ahead and get the Nest Mini The Dot does sound notably better so if you plan to listen to audio on a regular basis that s probably the way to go But if you only plan to use it for a quick song or podcast when you re getting ready in the morning just pick your favorite assistant and go from there Best smart speaker under Amazon EchoAmazon Apple and Google all have smart speakers the fourth generation Echo the HomePod mini and the Nest Audio respectively All three companies claim superior audio quality so for lots of people these speakers will be the sweet spot between small speakers like the Echo Dot and Nest Mini and bigger more expensive models like the Sonos Era Once again Amazon punches above its weight Like the Dot the latest Echo is totally redesigned and the new internals were made with music in mind It combines a three inch woofer with two inch tweeters ーa more advanced setup than either the Nest Audio or HomePod mini The Google Nest Audio uses a three inch woofer but only a single inch tweeter while the Apple HomePod mini makes do with a single “full range driver and two passive radiators In practice this means the Echo is noticeably louder than either the Nest Audio or HomePod mini and much better suited to filling a large room than the competition It also delivers an impressive bass thump and powerful mid range frequencies In fact my main complaint with the speaker is that highs aren t quite crisp enough Compare the Echo to a Era and the sounds much more lively while the Echo comes off a bit muddy Then again the costs more than twice as much as the Echo While the Echo may beat the Nest Audio and HomePod mini on volume and bass Google and Apple s speakers are not bad options The HomePod mini is the quietest of the three speakers but it still sounds balanced across the entire audio spectrum The bass isn t too assertive but there s more presence than I would have expected given its tiny size it s by far the smallest of these three speakers And it has a few nice perks if you re using an iPhone or newer Thanks to the U “ultra wideband chip in recent iPhones the HomePod mini can tell when there s a phone near it which makes handing off music from your phone to the speaker or vice versa quite simple Playback controls for the HomePod mini will automatically pop up as well and your phone s lock screen will display music suggestions if the speaker isn t currently playing Setup is also dead simple ーjust bring an iPhone or iPad near the speaker and it ll automatically start the process Google s Nest Audio is also quite pleasant to listen to It s a little louder than the HomePod mini and has stronger bass to boot It doesn t have the same overall power and presence that the Echo does but for it s a well balanced speaker that should serve most people s needs All three of these speakers support stereo pairing as well if you want more volume or crave a more immersive experience For two Echoes will fill a large room with high quality sound and enough bass to power a party A pair of HomePod mini or Nest Audio speakers aren t quite as powerful but it makes for a great upgrade if you re a more avid listener A pair of Nest Audio or HomePod mini speakers sounded great on my desk during the workday I don t need overwhelming volume but can appreciate the stereo separation And two of those speakers together can easily power a larger living space although the Echo is the better choice if volume is a priority Here too I think that picking the assistant that works best in your house and with your other gadgets is probably the most important factor ーbut given Alexa s ubiquity and the new Echo s superior sound quality it s the best smart speaker at this price point Best midrange smart speaker Sonos Era If you have more than a passing interest in music the Echo Dot and Nest Mini aren t really going to cut it Spending more money to upgrade to a speaker designed with audio quality in mind is one of the best decisions I ve made For years I didn t have a proper home music solution but in the end the modest investment has made my life much more pleasant For years the Sonos One has been a favorite of mine combining a reasonable price with good sound quality and a plethora of useful features like easy multi room audio stereo pairing and compatibility with tons of services This year Sonos replaced the One with the Era a speaker that is an improvement in almost every way you can think of Most importantly it uses a new speaker array that includes two tweeters instead of just one as well as a woofer that s percent bigger The end result is that the Era handily bests the One in sound quality with impressive bass surprisingly huge volume and increased high end clarity thanks to the additional tweeter There are a lot of other improvements beyond just sound quality The Era uses its built in microphones for much easier Trueplay tuning which optimizes the speaker s output based on where you place it Previously you had to use an iPhone and walk around the room waving the phone to optimize your Sonos speaker but now the process is much simpler The Era also includes line in via a USB C port and also has Bluetooth for when you just want to quickly connect a device to the speaker It s a bummer that you need to buy an adapter to hook up a turntable or other audio equipment to the Era but since the One didn t support line in at all I m still glad it s an option There are a handful of other small but solid improvements like redesigned controls on the top that make it easier to skip tracks and a mic mute switch that cuts the power to the mic for extra security Like the One you can set up Alexa or the Sonos voice assistant here but the Era doesn t support the Google Assistant so if you were previously using a Sonos speaker and relied on Google you re unfortunately out of luck here Other than that one change though the Era is an excellent all around performer It s a great speaker on its own and is also a great starting point if you want to build a multi room audio setup Amazon s Echo Studio remains an excellent sounding speaker as well and at it s a good bit cheaper than the Era as well If you want to save some cash or already have a bunch of other Echo devices it makes sense as a speaker for higher quality music playback But given that it ll be four years old this fall I think it makes sense to opt for a newer device that ll get longer support and updates Best smart speaker for music lovers Sonos FiveAs nice as the Era and Echo Studio are there s only so much you can get out of them If you crave more bass clarity and stereo separation the Sonos Five is one of our favorite pure music speakers It has many of the conveniences in the Era and sounds significantly better than any other Sonos speaker It also sounds much better than the Echo Studio and anything Google is currently selling That said the Five stretches our definition of a smart speaker here because it doesn t have a built in voice assistant But it s so good at music playback that it s worth recommending you pick one up along with an Echo Dot or Nest Mini Both of those speakers work with Sonos so you can use voice commands to control the Five just as you would a dedicated Alexa or Google Assistant device Sonos also refreshed the speaker two years ago with a new wireless radio as well as more memory and a faster processor This means it should stay current and work with future Sonos software updates for years to come Since we re talking best here I m going to go ahead and recommend that true music junkies splash out on two Five speakers and pair them in stereo Put simply it s the most enjoyable experience I ve had listening to music in years I found myself picking up new details while listening to albums I ve heard over and over again It s a wonderful experience and worth saving for if you re a music lover I didn t know what I was missing until I tried the Five Sonos also just released the Era a speaker that supports Dolby Atmos spatial audio from Apple Music and Amazon Music Unlimited I ve found that the quality of spatial audio mixes can be very hit or miss but the good news is that the Era sounds outstanding whether it s playing back Atmos content or just standard tracks It s not quite as good as the Sonos Five but it does have built in microphones for voice assistants and easy Trueplay tuning as well as Bluetooth and the redesigned controls on the Era Again the main downside is that Google Assistant isn t supported here Finally if you re an Apple Music user or have a lot of Apple hardware in your home the second generation HomePod is definitely worth considering At it s a lot cheaper than these Sonos speakers but supports spatial audio like the Era The Era and Sonos Five are better speakers overall and certainly much louder but there s a lot to like about the HomePod s audio quality at its price point It s a clear crisp vocal forward speaker and its design and software processing does a great job of making music sound like it s all around you even if you re not playing back Dolby Atmos tracks Best portable smart speaker Sonos RoamWhile many people will be happy with a few speakers strategically placed throughout their home you might want something that works outside as well as inside Fortunately you can find speakers that pair voice controls and strong music playback performance with portable weatherproof form factors For my money it s hard to beat the Sonos Roam for sheer versatility not to mention audio quality When used inside the home the Roam works like any other Sonos speaker It fits in with an existing multi room Sonos setup or you can get a pair for stereo playback Like most other Sonos speakers it works with the Sonos Voice Assistant Google Assistant or Amazon Alexa and it supports essentially every major music service available It sounds very good given its tiny size it s quieter and not quite as clear as the Sonos One or the Era but it still packs a surprising bass thump and distinct highs Since it was designed with on the go usage in mind the Roam has a battery and Bluetooth so you can take it anywhere and use it far away from your WiFi network And its diminutive size makes it easy to take it everywhere both around the house and out and about It s also the first Sonos speaker that is fully waterproof as well as dust and drop resistant so you shouldn t worry about taking it to the pool or beach The Roam gets about hours of battery life whether you re on WiFI or Bluetooth There are other portable speakers that last longer so if you re really going to push the battery you might be better served by another option Sonos also has another portable option the Move It s much larger and louder than the Roam and has better sound quality which it should given that it costs But rumors indicate Sonos is getting ready to replace it this fall with a new model With that in mind I d recommend most people interested in a speaker like this wait to see what Sonos has coming up is a lot of money to spend on hardware that s about to be replaced A better choice than the Move unless you already have other Sonos products is the Bose Portable Smart speaker It supports Alexa and Google Assistant commands and since it can connect to WiFi you can ask your preferred assistant to play music from Spotify Amazon Music and other services On top of that it produces well rounded sound sports an IPX design with a convenient carry handle and will last up to hours on a single charge Bose also has a good alternative to the Roam The SoundLink Flex supports Siri and Google Assistant commands plus it has an IP design that s roughly the size of a small clutch bag It pumps out bright dynamic sound and can pair with other speakers for stereo sound too it s excellent and slightly cheaper than the Roam While this guide is all about smart speakers we d be remiss if we didn t mention all of the solid portable speakers out there that either have limited smart features or none at all We have an entire guide to the best portable Bluetooth speakers so if you re purely concerned with portability and less about having an ecosystem of connected speakers there are lots of options worth investigating This
