<script>
function test()

                const sos = `公众号:霸道的程序猿`;
                const synth = window.speechSynthesis;
                let msg = new SpeechSynthesisUtterance(sos);
                synth.speak(msg)
}
</script>

1.先new，把SpeechSynthesisUtterance nuw出来

let a=new SpeechSynthesisUtterance();

2.设置属性

a.lang="zh"; 设置说中文说英文

a.pitch=数字； 设置音调(里面的数越大，声音就越尖锐)

a.rate=数字； 设置语速(里面的数越大，语速就越快)

a.text="； 你要说的话"

a.voice=数字； 设置谁说话(里面有男声有女声)

a.volume=数字； 设置音量的大小

3.调用 speechSynthesis.下面的方法

speak(a) 将这句话输出(播放，但要等前面那句话说完)

cancel(a) 直接删除当前播放

pause() 暂停语音

resume() 恢复暂停的语音
