I am looking for a flutter Text-to-Speech package that supports SSML, so the output can have better control for stress, phonetics and intonations in different languages.

It appears there is 1 type of package which require no 3rd party service and just speak with the chosen locale, rate and pitch, and a second remote type that needs to be called with SSML and have an audio file returned.

Type 1, local but no ssml
text_to_speech: ^0.2.3
galli_text_to_speech: ^0.0.1
tts
flutter_tts
etc..

Type 2, remote, account required for ssml
aws_poly_api
flutter_azure_tts: ^0.1.6
cloud_text_to_speech: ^2.3.2
deepgram_speech_to_text: ^2.1.1
etc..

I’ve spent days looking but cannot find a package of the 1st type, runs locally, offline but that supports SSML? Anyone know if such a thing exist?
