Those well versed with Australian accents are welcome to check out the latest tuning effort at https://eurpod.com/en_au_tuning.zip - this includes a much more improved pack that solves the 3 phonemes missing from the version initially there. This was part of the SpeechPlayer work in 2016, so whoever tuned these phonemes now gets to have their work live on.
@Tamasg Are you possibly going to do English Ireland, English South Africa, English Scotland and others? Just going off of some of the ones Vocalizer supports.
@mckensie @Tamasg I have a lot of suggestions like this to be honest, especially for dravidian languages, but considering that there are not many contributors, it would be extremely hard. We need possibly two testers for each english flavour or a fundamental hand-tuned phonemes that speechbox can read.
@kaveinthran @mckensie oof yeah, I don't see Scottish and New Zealand, Irish, South African - all of those have enough linguistic differences that I'd need to know native people in those areas who are willing to sit down and be on like, a voice server where we talk through their speech and tune it together or something. Would be doable but a lot of hard, ear-by-ear type listening and tuning type work. Australian got lucky because the add-on just sat there unused from 2016, never updated, and it was easy enough to compare the main vowels, raise them slightly (like 5%, not a lot) to make sure coarticulation doesn't mess with them, and we got fairly well there now I feel like. And there's way less research in terms of formant tables and targets for various English dialects, so a native speaker + the combination of existing English vowels to tune from ends up becoming an easier path.
@Tamasg @kaveinthran Indian English might get lucky too though, we haven't seen anything from that there though so we'll just have to wait
