IPA (or at least XSAMPA, but preferably IPA) in TTS for alerts
Many languages are not supported in TTS and unlikely to be supported. My interest in Latin, for example, is rather niche.
Allowing us to enter IPA in the “Text and Speech” portion of the alert setup would give a stopgap approximation of any language a streamer chose to use, as long as they could look up the IPA for it.
For example, I might want to greet new followers and people redeeming a check-in with “Salvē, Username!” ‘Salvē’ is properly pronounced [ˈs̠äɫ̪u̯eː], but the closest I can coax from Brian is ‘Sallwé’.
As an example of how the input might look, I have this sample of what I gave Narakeet for their implementation of Brian’s voice:
[kʷɪs̠]{ipa} [ˈhɔd̪ieː]{ipa} [ˈpriːmʊs̠]{ipa} [äd̪ˈu̯eːnɪt̪]{ipa}?
Including IPA as a phoneme input option won’t replace adding other languages, but it can work as a universal stopgap for those who need another language before Twitch formally adds it.
