Speech Recognition

aka Voice to Text API

TIP

Speech recognition is the ability of a machine or program to identify words and phrases in spoken language and convert them to a machine-readable format. Introduced in 2012 by W3C.
The HTML5 Speech Recognition API allows JavaScript to have access to a browser’s audio stream and to convert it to text.
