== Web Speech API ==

The [[Web Speech API]] aims to provide an alternative input method for web applications (without using a keyboard). With this API, developers can give web apps the ability to transcribe voice to text, from the computer's microphone. The recorded audio is sent to speech servers for transcription, after which the text is typed out for the user. The API itself is agnostic of the underlying speech recognition implementation and can support both server based as well as embedded recognizers.<ref>{{Cite web | url=http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Feb/att-0020/api-draft.html#introduction | title=API draft | access-date=January 28, 2012}}</ref>

The '''HTML Speech Incubator group''' has proposed the implementation of audio-speech technology in browsers in the form of uniform, [[Cross-platform software|cross-platform]] APIs. The API contains both:<ref>{{Cite web | url=https://wiki.mozilla.org/HTML5_Speech_API | title=HTML5 Speech API | access-date=January 28, 2012}}</ref>
