SpeechRecognition.continuous - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The continuous property of the SpeechRecognition 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.)

var recognition = new SpeechRecognition();
var speechRecognitionList = new SpeechGrammarList();
speechRecognitionList.addFromString(grammar, 1);
recognition.grammars = speechRecognitionList;
recognition.continuous = false;
recognition.lang = 'en-US';
recognition.interimResults = false;
recognition.maxAlternatives = 1;
