We have Speech. Recognition for understanding human voice and turning it into text Speech Text and Speech. Synthesis for reading strings out loud in a computer generated voice Text Speech. Well start with the former. The Speech Recognition API is surprisingly accurate for a free browser feature. It recognized correctly almost all of my speaking and knew which words go together to form phrases that make sense. It also allows you to dictate special characters like full stops, question marks, and new lines. The first thing we need to do is check if the user has access to the API and show an appropriate error message. Unfortunately, the speech to text API is supported only in Chrome and Firefox with a flag, so a lot of people will probably see that message. Speech. Recognition window. Speech. Recognition window. Speech. Recognition. Speech. Recognition. The recognition variable will give us access to all the APIs methods and properties. There are various options available but we will only set recognition. This will enable users to speak with longer pauses between words and phrases. Before we can use the voice recognition, we also have to set up a couple of event handlers. Most of them simply listen for changes in the recognition status recognition. Voice recognition activated. Try speaking into the microphone. You were quiet for a while so voice recognition turned itself off. No speech was detected. Try again. There is, however, a special onresult event that is very crucial. It is executed every time the user speaks a word or several words in quick succession, giving us access to a text transcription of what was said. When we capture something with the onresult handler we save it in a global variable and display it in a textarea recognition. Speech. Recognition. Event object. It holds all the lines we have captured so far. We only need the current one. Index. Get a transcript of what was said. Add the current transcript to the contents of our Note. Content transcript. Textarea. valnote. Content. The above code is slightly simplified. There is a very weird bug on Android devices that causes everything to be repeated twice. There is no official solution yet but we managed to solve the problem without any obvious side effects. With that bug in mind the code looks like this var mobile. Repeat. Bug current 1 transcript event. Repeat. Bug. note. Content transcript. Textarea. valnote. Content. Once we have everything set up we can start using the browsers voice recognition feature. To start it simply call the start method start record btn. This will prompt users to give permission. If such is granted the devices microphone will be activated. Most APIs that require user permission dont work on non secure hosts. Make sure you are serving your Web Speech apps over HTTPS. The browser will listen for a while and every recognized phrase or word will be transcribed. The API will stop listening automatically after a couple seconds of silence or when manually stopped. With this, the speech to text portion of our app is complete Now, lets do the opposite Text to Speech. Speech Synthesys is actually very easy. The API is accessible through the speech. Synthesis object and there are a couple of methods for playing, pausing and other audio related stuff. It also has a couple of cool options that change the pitch, rate, and even the voice of the reader. All we will actually need for our demo is the speak method. It expects one argument, an instance of the beautifully named Speech. Synthesis. Utterance class. Here is the entire code needed to read out a string. Out. Loudmessage. Speech. Synthesis. Utterance. Set the text and voice attributes. Synthesis. speakspeech. When this function is called, a robot voice will read out the given string, doing its best human impression. Conclusion. In an era where voice assistants are more popular then ever, an API like this gives you a quick shortcut to building bots that understand and speak human language. Adding voice control to your apps can also be a great form of accessibility enhancement. Users with visual impairment can benefit from both speech to text and text to speech user interfaces. The speech synthesis and speech recognition APIs work pretty well and handle different languages and accents with ease. Sadly, they have limited browser support for now which narrows their usage in production. If you need a more reliable form of speech recognition, take a look at these third party APIs.
