English voices diversity

hi,

Hoping that you are well. As promised earlier, please find below the requests:

- We need more variety and diverse voices in terms of English. We need English (South Africa, Tanzania, Nigeria, Kenya, etc) voices, both male and female please.

- Please integrate functionality for user to control speech / voice of the avatar. They can be very fast as they are and would like to slow them down depending on use-case.

I look forward to your feedback on the above.

Best wishes,
