Google's new Chrome stable release version 11.0.696.57 today enabled: "speech input through HTML."
"Using Chrome, you can now translate what you say into other languages with Google Translate. If you're translating from English, just click on the microphone on the bottom right of the input box, speak your text, and choose the language you want to translate to. In fact, you can even click on the "Listen" feature to hear the translated words spoken back to you!," informs Google.
"Speech input through HTML is one of many new web technologies in the browser that help make innovative and useful web applications like Google Translate's speech feature possible. If you'd like to check out more examples of applications built using the latest and greatest web technologies in the browser, you can check out more than 200 submissions by web developers on chromeexperiments.com," Google added.
