这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

continuous 特性为 SpeechRecognition interface controls whether continuous results are returned for each recognition, or only a single result.

It defaults to single results ( false )。

句法

var myContinuous = mySpeechRecognition.continuous;
mySpeechRecognition.continuous = true;
					

值

A 布尔 representing the current SpeechRecognition 's continuous status. true means continuous, and false means not continuous (single result each time.)

范例

This code is excerpted from our Speech color changer 范例。

var grammar = '#JSGF V1.0; grammar colors; public <color> = aqua | azure | beige | bisque | black | blue | brown | chocolate | coral | crimson | cyan | fuchsia | ghostwhite | gold | goldenrod | gray | green | indigo | ivory | khaki | lavender | lime | linen | magenta | maroon | moccasin | navy | olive | orange | orchid | peru | pink | plum | purple | red | salmon | sienna | silver | snow | tan | teal | thistle | tomato | turquoise | violet | white | yellow ;'
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;
