这里想要实现安卓浏览器也可以支持文本转语音的功能，但是安卓系统下载的chrome浏览器输出栏中显示
Voice support NOT ready
Voice not supported. Using fallback mode
Mapped UK English Female to en-GB fallback voice
Mapped UK English Male to en-GB fallback voice
Mapped US English Female to en-US fallback voice
Mapped Spanish Female to es fallback voice
Mapped French Female to fr fallback voice
Mapped Deutsch Female to de fallback voice
Mapped Italian Female to it fallback voice
Mapped Hungarian Female to hu fallback voice
Mapped Serbian Male to sr fallback voice
Mapped Croatian Male to hr fallback voice
Mapped Bosnian Male to bs fallback voice
Mapped Fallback UK Female to en-GB fallback voice
有什么第三方库可以支持文本转语音，要求完全免费，不是什么免费额度

Answer 1

web api提供的方法并不是不可用，只是因为安卓设备的默认tts引擎设置的问题，在Google play中下载Speech Recognition & Synthesis插件后再设置中将tts换位谷歌的引擎之后就可以正常获取到语音列表了
