I have closed #817 because I copied main branch only yesterday.

I suggest not modifying the autoPlayAudio option. We should add a new pronunciation option instead. Mixing them together will complicate the options.

Especially considering that later on, we might add an option to automatically play the queried text, not just English words.

I got it, I'll put back autoPlayAudio property as boolean and add a new pronunciation option.

@tisfeng Add a new option for selecting pronunciation only.

Good job!

I suggest not binding the English pronunciation method with autoPlayAudio, it should be a separate option because besides automatic playback, there's also manual playback, and users will need this option in that case.

Besides Youdao, there are other TTS services that also support British/American accents, such as Baidu and Bing.

If you're interested, you can submit another PR later.

Looks good.
