there's no voice named 'english-us' by espeak-ng default installation, you can set it to 'en' or 'en-us'

Please do not change indentation. If voice names have changed, I guess we need to update tests as well.

there are no indentations changed, only some white space trimmed at line end

I searched in https://brew.sh/ and found espeak, but no espeak-ng, I guess you can only brew install espeak.
They seem to have some problems unresolved with espeak-ng on mac espeak-ng/espeak-ng#12.
I hope this will solve #1 , but I don't have a mac to confirm . I tested it on Ubuntu18 and Win10
I have a little robot project, it's tts function depends on py-espeak-ng. I hope it support all platforms

This looks like a hack to me. We could look into auto-detecting the availability of first espeak-ng and, as a fallback espeak on a system and use the best available option.
