我正在尝试在移动设备上做一些语音识别的东西。这里有一些代码…
var recognition = new webkitSpeechRecognition();
recognition.onresult = function (e) {
//This is called every time the Speech Recognition hears you speak.
//You may say "How's it going today", the recognition will try to
//interpret what you're saying while you're speaking. For example, while
//you're speaking it may go.. "house" "how's it going" "how's it going today"
//as it interprets it returns an object that contains properties, one of
//which is "e.results[i].isFinal" where "i" is an array of returned objects.
//In this case the object with a transcript of "house" would have a
//"e.results[i].isFinal" value of false. Where as the object with a transcript
//of "how's it going today" would have a "e.results[i].isFinal" value of
//true.. Because this is the FINAL INTERPRETATION of this particular transcript.
//HOWEVER.. The problem I'm having is that when using a mobile device, the "e.results[i].isFinal" always
//has a value of true, even when it's not the final interpretation. It works correctly on desktop however. Both are using Chrome.
if(e.results[e.results.length-1].isFinal){
var finalTranscript = '';
for(i=0;i<e.results.length;i++){
finalTranscript += e.results[i][0].transcript;
}
console.log(finalTranscript);
document.getElementById('output').innerHTML = finalTranscript;
}
}
我只是想知道是否有人遇到过这个问题,以及如何解决这个问题。我在我的网站上有一个例子。
https://jaymartmedia.com/example/speech.html我在页面上添加了一些调试信息(以便我可以在移动设备上"看到"控制台)。在桌面上,你会注意到"2:Final: false",有时会出现"2:Final: true"。这是"e.results[i]. isfinal"的值。在手机上,它总是(或者至少每次我在手机上尝试时)是"2:Final: true"。
这引起了重大问题,任何见解将不胜感激。
我找不到直接的解决方法。
但是在我的情况下,它解决了当我禁用所有中间结果时的错误:
var recognition = new webkitSpeechRecognition();
recognition.continuous = false
// or
recognition.interimResults = false
