我试图检测用户何时暂停并再次开始说话而不停止识别。这是我设置的代码,用于检测用户何时进行会话并将其输出到页面:
//set up vars
var final_transcript;
var recognizing = false;
//check if using chrome and up to date
if ('webkitSpeechRecognition' in window) {
//init
var recognition = new webkitSpeechRecognition();
recognition.continuous = true;
recognition.interimResults = true;
recognition.onstart = function() {
recognizing = true;
};
//if there is error somewhere
recognition.onerror = function(event) {
console.log(event.error);
};
recognition.onend = function() {
recognizing = false;
};
//after giving the spech
recognition.onresult = function(event) {
var interim_transcript = '';
for (var i = event.resultIndex; i < event.results.length; ++i) {
if (event.results[i].isFinal) {
// finilize and show the compleated text
final_transcript += event.results[i][0].transcript;
} else {
// run the speech and output it
interim_transcript += event.results[i][0].transcript;
}
}
final_transcript = capitalize(final_transcript);
final_span.innerHTML = linebreak(final_transcript);
interim_span.innerHTML = linebreak(interim_transcript);
};
}
var two_line = /\n\n/g;
var one_line = /\n/g;
function linebreak(s) {
return s.replace(two_line, '<p></p>').replace(one_line, '<br>');
}
function capitalize(s) {
return s.replace(s.substr(0,1), function(m) { return m.toUpperCase(); });
}
function startDictation(event) {
if (recognizing) {
recognition.stop();
return;
}
final_transcript = '';
recognition.lang = 'en';
recognition.start();
}
//startDictation();
&#13;
<div id="results">
<span id="final_span" class="final"></span>
<span id="interim_span" class="interim"></span>
</div>
&#13;
那么有没有办法检测用户何时暂停以及他暂停的时间长度?
答案 0 :(得分:1)
这不是一个完整的答案,但它已经开始。

我不确定onspeechstart
事件是否仅触发一次,或者如果我在一个噪音较小的区域,它会再次发射。
如果它多次触发,这很容易做到,因为我们可以存储speech start
和speech end
次,并从那里找出沉默的时期。
如果它onspeechstart
只触发一次,那么你可以找到一种方法来获得给定文本的平均语音持续时间,并从那里找出沉默。
但是,每次捕获单词时都会触发一个事件:onresult
。
所以基本的想法是定义一个activity
数组,你可以push
语音数据进入,然后分析沉默时期。
代码:
let activity = []
recognition.onresult = event => {
console.log(event)
activity.push('Ended:' + event.timeStamp)
}
recognition.onspeechstart = event => {
activity.push('Started:' + event.timeStamp)
}
recognition.onend = event => {
console.log(activity)
}
