This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
The continuous

interface controls whether continuous results are returned for each recognition, or only a single result.
It defaults to single results (false

Syntax
var myContinuous = mySpeechRecognition.continuous; mySpeechRecognition.continuous = true;
Value
A Boolean
representing the current SpeechRecognition
's continuous status. true
means continuous, and false
means not continuous (single result each time.)
