With speech recognition in the browser you can enable users to speak to your site across everything from a voice search to creating an interactive bot as part of the application.Let's see how the API works and what we can build with it. In 2018, Google reported that 27% of the global online population is using voice search on mobile. We previously investigated text to speech so let's take a look at how browsers handle recognising and transcribing speech with the SpeechRecognition API.Being able to take voice commands from users means you can create more immersive interfaces and users like using their voice. The Web Speech API has two functions, speech synthesis, otherwise known as text to speech, and speech recognition, or speech to text. Listen to the TTS voicesIn our research study, participants listened to one of 21 voices reading an article Reduce Your Stress in Two Minutes a Day.Here are brief clips of each of those voices reading the first two sentences of the article:“Bill Rielly had it all: a degree from West Point, an executive position at Microsoft, strong faith, a great family life, and plenty of money.
Text To Speech For Firefox How To Get TheIt should look like this:With that in place, let's see how to get the browser to listen to and understand us. Make sure the files are in the same directory and then open the HTML file in the browser. Once you have those prepared, create a new directory to work in and save this starter HTML and CSS to that directory.Once you stop speaking you should see a SpeechRecognitionEvent posted in the console.There is a lot going on in these 3 lines of code. Run the code and, once you've given the permission, say something into your microphone. Enter the following in the console:When you run that code Chrome will ask for permission to use your microphone and then, if your page is being served on a web server, remember your choice. In Chrome open up your dev tools.![]() ![]() Well, there is one result object as we only said one thing before it stopped listening. The most important property is results which is a list of SpeechRecognitionResult objects. There are settings we'll see later that allow continuous transcription and interim results as you speak.Let's dig into the SpeechRecognitionEvent object. Also, you only receive the final result from the speech recognition service. To continue transcription you need to call start again. Once the object receives a result it will stop listening. In a previous post we also saw how the browser can speak to us. Now we can talk to the browserIn this post you've seen how we can talk to the browser and have it understand us. There'd be a bit more work to do here if we wanted to turn this into dictation, for example. Best virus protection for bots macI recently saw a great example of a voice based game in the browser. And if you want the source code, it's available in my web-assistant repo on GitHub.There are all sorts of opportunities for interesting user interfaces using speech.
