An Orpheus id (groq-orpheus-english) did not start with "local-", so
generate_tts_audio sent it down the OpenAI path and every call failed. It
also could be added with no voice, and the "local-%" filters in /tts/voices
and the default lookup hid any non-local voice from learners even when it
was added and marked default.
services/tts_voices.py is the one table of which voices belong to which
model (Kokoro, Orpheus English/Arabic, Fish), the same table the scribe app
keeps. Anything the table knows, or anything local-*, goes through the
LiteLLM gateway with the options its family needs (Orpheus: wav). Adding a
bare model id creates one row per voice with friendly names, so an
administrator adds "groq-orpheus-english" and six voices appear to test one
by one; a voice from another family is refused, naming the ones that work.
Learners are offered every active voice, each saying which model serves it,
and /tts/speak answers with the media type the model actually returned.
Kitten and Supertonic tables go — those models left the gateway.
