A user with tts.openai.model set to a direct-OpenAI model (e.g. tts-1-hd)
but no VOICE_TOOLS_OPENAI_KEY/OPENAI_API_KEY (or with tts.use_gateway)
routes TTS through the managed Nous audio gateway, which only proxies
gpt-4o-mini-tts. The request 400s with:
VALIDATION_ERROR: Unsupported managed OpenAI speech model
{'model': 'tts-1-hd', 'supportedModels': ['gpt-4o-mini-tts']}
_resolve_openai_audio_client_config now reports whether it resolved the
managed gateway; _generate_openai_tts coerces the model to a
managed-supported one (logging a warning that points at the direct-key
escape hatch) unless the user redirected base_url to their own endpoint.
Direct-key users keep their tts-1/tts-1-hd preference unchanged.
Follow-up on @pty819's t2a_v2 endpoint fix:
- Default model: speech-02 -> speech-02-hd (bare 'speech-02' is not in the
supported enum; t2a_v2 rejects it with 400). Official enum: speech-01-hd,
speech-01-turbo, speech-02-hd, speech-02-turbo, speech-2.6-hd/turbo,
speech-2.8-hd/turbo.
- Default voice: female-shaonv -> English_expressive_narrator. The
legacy speech-01-series short ID doesn't resolve cleanly on the
speech-02+ models that are now the default.
- Default base URL: api.minimaxi.com -> api.minimax.io (matches the
canonical host in the published docs; api-uw.minimax.io is the
reduced-latency alt).
- Add GroupId support via tts.minimax.group_id config or MINIMAX_GROUP_ID
env var. Some MiniMax accounts scope TTS requests by group; without it,
requests 401. Only appended when not already in the user's base_url.
Tests rewritten to cover both the default t2a_v2 path (hex-encoded audio
in JSON, nested voice_setting/audio_setting) and the legacy
text_to_speech path (raw audio bytes, flat payload). Adds coverage for
GroupId config/env wiring and error surfacing.
Also adds AUTHOR_MAP entry for pty819's GitHub-noreply email.
MiniMax deprecated the old v1/t2a_v2 endpoint (api.minimax.io) and
moved to v1/text_to_speech (api.minimax.chat). The new API:
- Uses a flat payload: {model, text, voice_id} instead of nested
voice_setting / audio_setting objects
- Returns raw audio bytes (Content-Type: audio/mpeg) instead of
JSON with hex-encoded audio
- Uses model 'speech-01' instead of 'speech-2.8-hd'
- Updated default voice_id to 'female-shaonv' for Chinese TTS
The implementation detects Content-Type to handle both old and new
API responses, maintaining backward compatibility for any users who
manually configured the legacy base_url.
