[英]How to allow speech recogonition api in QWebEngineView
我有一个小代码
<!doctype html>
<head>
<title>JavaScript Speech to Text</title>
</head>
<body>
<h2>JavaScript Speech to Text</h2>
<p>Click on the below button and speak something...</p>
<p><button type="button" onclick="runSpeechRecognition()">Speech to Text</button> <span id="action"></span></p>
<div id="output" class="hide"></div>
<script>
/* JS comes here */
function runSpeechRecognition() {
// get output div reference
var output = document.getElementById("output");
// get action element reference
var action = document.getElementById("action");
// new speech recognition object
var SpeechRecognition = SpeechRecognition || webkitSpeechRecognition;
var recognition = new SpeechRecognition();
// This runs when the speech recognition service starts
recognition.onstart = function() {
action.innerHTML = "<small>listening, please speak...</small>";
};
recognition.onspeechend = function() {
action.innerHTML = "<small>stopped listening, hope you are done...</small>";
recognition.stop();
}
// This runs when the speech recognition service returns result
recognition.onresult = function(event) {
var transcript = event.results[0][0].transcript;
var confidence = event.results[0][0].confidence;
output.innerHTML = "<b>Text:</b> " + transcript + "<br/> <b>Confidence:</b> " + confidence*100+"%";
output.classList.remove("hide");
};
// start recognition
recognition.start();
}
</script>
</body>
它不适用于 PyQtWebEngine 如何使其工作。
我搜索了一下,发现只有基于 chromium 的浏览器支持语音识别。
PyQtWebEngine 是基于 Chromium 的,那么如何使它工作
尽管此功能在铬中可用,但已被 Qt 禁用,如本报告所示。 也许在 Qt6 的以下版本中将启用它。
