// SpeechSynthesisUtterance.lang 获取并设置话语的语言
// SpeechSynthesisUtterance.pitch 获取并设置话语的音调(值越大越尖锐, 越低越低沉)
// SpeechSynthesisUtterance.rate 获取并设置说话的速度(值越大语速越快, 越小语速越慢)
// SpeechSynthesisUtterance.text 获取并设置说话时的文本
// SpeechSynthesisUtterance.voice 获取并设置说话的声音 目前
// SpeechSynthesisUtterance.volume 获取并设置说话的音量
window.speechSynthesis.speak(utterThis); //这样就会有个美女姐姐语音朗读 张三，扫码成功！
