Chrome implemented the HTML5 speech recognition API. Many languages are supported. I wanna know which languages are supported and each language's corresponding code which is used in the HTML element's lang attribute.
For instance:
Thank you!
Ok, if it is not published, we can try to at least figure this out. Let me put this table for the beginning and we will refine it if someone has more information.
I'm making assumption that supported languages shall be similar to those supported by voice search and that google uses standard language codes and does that consistently across its services.
I've looked up languages supported by voice search on wikipedia
I've found language codes here, on google language settings page and here
EDIT: I've experimented with backend voice recognition service. I've run a series of tests where I've passed the same english speech sample to the API but specified different dialect every time. It looks like:
I treat a dialect as supported if recognition gives a different result from en-US and from main dialect for the language. Still, to verify it 100% we need to run samples for each language.
Legend
+ Most of all supported, because test gives a result different from en-US and main dialect..+ Absent on wikipedia but most of all supported, because test gives result different from en-US and main dialect.+? Most of all supported because it is listed on wikipedia. But test on my sample gives result identical to the main dialect. So either this is a coinsidense or language code is wrong..+? Not listed on wikipedia but looks like supported, because test gives result different from en-US and main dialect.Languages

I know this is an old post, but since this information is annoyingly hard to find I thought I'd post a list for anyone who might be looking. Please leave a note if you find any errors or omissions.

Edit: I also found this list, which is probably more current: https://cloud.google.com/speech-to-text/docs/languages
Edit 2: Adding this list of sample voices as well: https://cloud.google.com/text-to-speech/docs/voices
Use the following code to get all available voices for the speech API in your browser:
var voices = speechSynthesis.getVoices();
for(var i = 0; i < voices.length; i++ ) {
console.log("Voice " + i.toString() + ' ' + voices[i].name + ' ' + voices[i].uri);
}
At this time only Chrome and Safari support the Web Speech API (although Safari only supports the Text to Speech functionalities). Curiously Firefox OS supports TTS but the browser version does not.
The list of languages depends on what browser you are on according to both the documentation and my tests (user agent dependent).
In Safari you also get lots of languages available (I believe over 40). In Chrome, at this time you get the following list:
Voice 0 Google US English undefined
Voice 1 Google UK English Male undefined
Voice 2 Google UK English Female undefined
Voice 3 Google Español undefined
Voice 4 Google Français undefined
Voice 5 Google Italiano undefined
Voice 6 Google Deutsch undefined
Voice 7 Google 日本人 undefined
Voice 8 Google 한국의 undefined
Voice 9 Google 中国的 undefined
Voice 10 native undefined
