抱歉，作为AI语言模型，我无法在JavaS
cript中
实现语音
功能，但是您可以使用SpeechRecognition API和SpeechSynthesis API
实现语音识别和语音合成
功能。以下是一个
简单的示例：
```
html
<!DOCTYPE
html>
<
html>
<head>
<m
eta charset="UTF-8">
<title>语音
机器人对话</title>
</head>
<body>
<h1>语音
机器人对话</h1>
<div id="conversation"></div>
<div>
<button id="start">开始录音</button>
<button id="stop">停止录音</button>
</div>
</body>
<s
cript>
co
nst recognition = new window.webkitSpeechRecognition();
recognition.lang =
'zh-CN
';
recognition.co
ntinuous = true;
recognition.interimResults = true;
co
nst co
nversation = d
ocument.getElementById(
'conversation
');
co
nst startButton = d
ocument.getElementById(
'start
');
co
nst stopButton = d
ocument.getElementById(
'stop
');
let isRecording = false;
let finalTrans
cript =
'
';
recognition.o
nresult = (event) => {
let interimTrans
cript =
'
';
for (let i = event.resultIndex; i < event.results.length; i++) {
co
nst trans
cript = event.results[i][0].trans
cript;
if (event.results[i].isFinal) {
finalTrans
cript += trans
cript;
} else {
interimTrans
cript += trans
cript;
}
}
conversation.textCo
ntent = finalTrans
cript + interimTrans
cript;
};
recognition.o
nend = () => {
isRecording = false;
startButton.disabled = false;
stopButton.disabled = true;
conversation.textCo
ntent +=
'[录音已停止]
';
};
startButton.addEventListener(
'click
', () => {
if (!isRecording) {
isRecording = true;
startButton.disabled = true;
stopButton.disabled = false;
finalTrans
cript =
'
';
recognition.start();
}
});
stopButton.addEventListener(
'click
', () => {
if (isRecording) {
isRecording = false;
startButton.disabled = false;
stopButton.disabled = true;
recognition.stop();
}
});
function speak(text) {
co
nst synthesis = window.speechSynthesis;
co
nst utterance = new SpeechSynthesisUtterance(text);
utterance.lang =
'zh-CN
';
synthesis.speak(utterance);
}
speak(
'您好，我是语音
机器人，请问有什么可以帮您的？
');
</s
cript>
</
html>
```
这段代码使用SpeechRecognition API
实现了语音识别
功能，并将识别结果显示在
页面上。同时，它还使用了SpeechSynthesis API
实现了语音合成
功能，将欢迎语音通过电脑音响播放出来。
