What is Web Speech API?
The Web Speech API was launched in late 2012 and enables developers to provide the input speech and text-to-speech output capabilities in a web browser. This API takes care of the privacy of users because before leaving the site to access the voice through a microphone, the user must explicitly grant permission. Interestingly, the application shall be the same as the getUserMedia API, although not need the webcam. If the page that implements this API uses the HTTPS protocol, the browser asks permission only once.
