Custom Python gTTS voice

If you call "gtts-cli --all" from a command prompt, you can see that gTTS actually supports a lot of voices. However, you can only change the accents, and not the gender.

Unfortunately it does not appear you can do that. The script uses this webpage to grab voice from, and it appears all you can do is have one voice per language.

Reading the actual source shows that your next best bet would be to try to pass a different language that is still English (for example, en-uk). It may produce a different result that is still English but with a different dialect.
