SpeechRecognition 接口在 Web 语音 API is the controller interface for the recognition service; this also handles the SpeechRecognitionEvent sent from the recognition service.

注意 : On some browsers, like Chrome, using Speech Recognition on a web page involves a server-based recognition engine. Your audio is sent to a web service for recognition processing, so it won't work offline.

构造函数

SpeechRecognition.SpeechRecognition()

创建新的 SpeechRecognition 对象。

特性

SpeechRecognition also inherits properties from its parent interface, EventTarget .

SpeechRecognition.grammars

Returns and sets a collection of SpeechGrammar objects that represent the grammars that will be understood by the current SpeechRecognition .

SpeechRecognition.lang

Returns and sets the language of the current SpeechRecognition . If not specified, this defaults to the HTML lang attribute value, or the user agent's language setting if that isn't set either.

SpeechRecognition.continuous

Controls whether continuous results are returned for each recognition, or only a single result. Defaults to single ( false )。

SpeechRecognition.interimResults

Controls whether interim results should be returned ( true ) 或不 ( false .) Interim results are results that are not yet final (e.g. the SpeechRecognitionResult.isFinal 特性为 false )。

SpeechRecognition.maxAlternatives

Sets the maximum number of SpeechRecognitionAlternative s provided per result. The default value is 1.

SpeechRecognition.serviceURI

Specifies the location of the speech recognition service used by the current SpeechRecognition to handle the actual recognition. The default is the user agent's default speech service.

方法

SpeechRecognition also inherits methods from its parent interface, EventTarget .

SpeechRecognition.abort()

Stops the speech recognition service from listening to incoming audio, and doesn't attempt to return a SpeechRecognitionResult .

SpeechRecognition.start()

Starts the speech recognition service listening to incoming audio with intent to recognize grammars associated with the current SpeechRecognition .

SpeechRecognition.stop()

Stops the speech recognition service from listening to incoming audio, and attempts to return a SpeechRecognitionResult using the audio captured so far.

事件

监听这些事件使用 addEventListener() 或通过把事件监听器赋值给 on eventname 特性为此接口。

audiostart

Fired when the user agent has started to capture audio.
也可用凭借 onaudiostart 特性。

audioend

Fired when the user agent has finished capturing audio.
也可用凭借 onaudioend 特性。

end

Fired when the speech recognition service has disconnected.
也可用凭借 onend 特性。

error

Fired when a speech recognition error occurs.
也可用凭借 onerror 特性。

nomatch

Fired when the speech recognition service returns a final result with no significant recognition. This may involve some degree of recognition, which doesn't meet or exceed the confidence threshold.
也可用凭借 onnomatch 特性。

result

Fired when the speech recognition service returns a result — a word or phrase has been positively recognized and this has been communicated back to the app.
也可用凭借 onresult 特性。

soundstart

Fired when any sound — recognisable speech or not — has been detected.
也可用凭借 onsoundstart 特性。

soundend

Fired when any sound — recognisable speech or not — has stopped being detected.
也可用凭借 onsoundend 特性。

speechstart

Fired when sound that is recognised by the speech recognition service as speech has been detected.
也可用凭借 onspeechstart 特性。

speechend

Fired when speech recognised by the speech recognition service has stopped being detected.
也可用凭借 onspeechend 特性。

start

Fired when the speech recognition service has begun listening to incoming audio with intent to recognize grammars associated with the current SpeechRecognition .
也可用凭借 onstart 特性。

范例

In our simple Speech color changer example, we create a new SpeechRecognition object instance using the SpeechRecognition() constructor, create a new SpeechGrammarList , and set it to be the grammar that will be recognised by the SpeechRecognition instance using the SpeechRecognition.grammars 特性。

After some other values have been defined, we then set it so that the recognition service starts when a click event occurs (see SpeechRecognition.start() .) When a result has been successfully recognised, the SpeechRecognition.onresult handler fires,  we extract the color that was spoken from the event object, and then set the background color of the <html> element to that color.

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;
var diagnostic = document.querySelector('.output');
var bg = document.querySelector('html');
document.body.onclick = function() {
  recognition.start();
  console.log('Ready to receive a color command.');
}
recognition.onresult = function(event) {
  var color = event.results[0][0].transcript;
  diagnostic.textContent = 'Result received: ' + color;
  bg.style.backgroundColor = color;
}
