Speech-to-text. No speech model here covers Tswana: 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.
