Which open models work for Tongan?
Windy Translate lists 5 open translation models into Tongan and 4 from Tongan. All of them can be downloaded from Hugging Face and run on your own hardware. By licence: 9 Apache-2.0 (terms and attribution text: licensing). None of them has a screening score yet: FLORES-200, the test set used here, does not cover these pairs, so test them on your own text before you rely on them.
With English. English to Tongan: translate-en-to (not yet scored). Tongan to English: translate-to-en (not yet scored). To translate between Tongan and a language with no direct model, you can go through English with these two.
Speech-to-text. No speech model here covers Tongan: there is no dedicated model, and Whisper's tokenizer does not list the language.
Each model page has a short snippet to download and run the model yourself, its licence and attribution text, and its score where there is one. Pick the best scored model for your direction, then try it on a few sentences of your own text: a screening score is a starting point, not a guarantee.
