Question

我正在嘗試執行webkitSpeechGrammarList。就像你看到的那樣。但是當我說一個字，它在我的grammar之外時，我將得到結果而不是"I didnt recognise 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 webkitSpeechRecognition(); 
var speechRecognitionList = new webkitSpeechGrammarList(); 
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'); 


recognition.start(); 


recognition.onresult = function(event) { 
    var color = event.results[0][0].transcript; 
    diagnostic.textContent = 'Result received: ' + color + '.'; 
    bg.style.backgroundColor = color; 
} 

recognition.onspeechend = function() { 
    recognition.stop(); 
} 

recognition.onnomatch = function(event) { 
    diagnostic.textContent = 'I didnt recognise that color.'; 
} 

所以，因爲這都是實驗技術。我想知道..這是真的實施？我怎麼知道？
