const synthesizer = new SpeechSDK.SpeechSynthesizer(speechConfig, undefined);
const result = await synthesizer.speakTextAsync(content);
const time = (result.duration / (60 * 10000000)).toFixed(2);
output.innerText += `\n如果配音，大概需要 ${time} 分钟`;
} else {
output.innerText += '\n没有汉字需要配音';

clearBtn.addEventListener('click', () => {

<p>需要引入 Microsoft Cognitive Services Speech SDK 库，将其添加到代码中即可。具体方法请参考该库的官方文档。</p>
