Text to Speach -Regional British Accents

There is an exhaustive list of voice types, but I wanted to find something more regional. Would it be possible to have a Liverpudlian (Scouse), Yorkshire, Birmingham or even a Scottish or Geordie accents?

I’m sure there might be a few other accent requests that I have not mentioned - it’s just the British English ones all seem to be recessed pronunciation. Cockney/London and others could all help add more personality.

I am sure that other languages may have requests too.

Any thoughts ?

That is s jump link to where they talk about contributing language(s) and intents.

Ask in one of the suggested places there.

This is not really a feature request though. The stuff is in place to donate language and dialects…
