Consolidates all TTS text-preparation paths onto
tools/tts_text_normalize.prepare_spoken_text:
- strip_nonspoken_blocks: removes <think> reasoning blocks (#34213,
incl. unterminated streaming blocks) and the end-of-turn
file-mutation verifier footer emitted by run_agent.py (#40772).
- flatten_newlines_for_payload: collapses newlines into sentence
breaks so newline-sensitive OpenAI-compatible providers (Kokoro)
speak the whole script instead of truncating at the first newline
(#9004).
- tools/tts_tool._strip_markdown_for_tts (voice-mode streaming + web
dashboard path) now delegates to the shared cleaner, with the legacy
regex pipeline kept as a best-effort fallback.
- hermes_cli/voice.py speak_text and cli.py _voice_speak_response now
use the shared cleaner instead of their own duplicated regex
pipelines.
- gateway auto-TTS fallback also strips think blocks.
Tests: tests/tools/test_tts_prepare_spoken.py covers think blocks,
verifier footer, emoji, newline flattening, and the shared-cleaner
wiring on the tool/streaming/gateway paths. Updated the header
expectation in test_voice_cli_integration.py for the heading-fold
behavior of the shared cleaner.
Closes#34213, #9004, #40772
Address review feedback on #31693:
- Regression tests assert extra_body == {"lang_code": ...} is forwarded
when tts.openai.language is configured, and omitted when unset/empty
- Document tts.openai.language as intended for OpenAI-compatible
endpoints that support lang_code (e.g. Kokoro-FastAPI)

Add optional 'speed' parameter (0.25-4.0) to the text_to_speech tool
schema and handler. When provided by the model, it overrides the
config-level tts.speed setting, enabling per-request speed control
without config changes.
Use cases:
- Language learning: slow playback (0.5x) for pronunciation practice
- Accessibility: adjustable speed for hearing preferences
- Content review: accelerated playback for long text
The speed value is clamped to [0.25, 4.0] and injected into tts_config
before dispatching to any provider (Edge, OpenAI, MiniMax, etc.), so
all existing provider-level speed handling works transparently.
Includes 3 new tests for tool-level speed injection, clamping, and
config preservation when speed is not specified.
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.
