- Plugins/OpenCode: strip unsupported disabled Responses reasoning payloads for OpenCode image understanding. Fixes #70252.

- Plugins/OpenCode/OpenCode Go: register image understanding metadata so the image tool is available for OpenCode catalog models with vision support. Fixes #70482 and #61789.

- Providers/ElevenLabs: omit the MP3-only `Accept` header for PCM telephony synthesis, so Voice Call requests for `pcm_22050` no longer receive MP3 audio. Fixes #67340. Thanks @marcchabot.

- Providers/MiniMax TTS: truncate fractional pitch overrides before sending T2A requests, matching MiniMax's integer pitch contract while preserving fractional speed and volume. Fixes #62144.

- Providers/MiniMax TTS: transcode voice-note targets to Opus so Feishu/Telegram receive native voice messages instead of MP3 file attachments. Fixes #63540, #64134, and #70445.

- Providers/Microsoft TTS: keep allowlisted bundled speech providers discoverable even when another speech plugin has already registered, so Edge/Microsoft TTS is available alongside OpenAI. Fixes #62117 and #66850.

- Providers/Microsoft TTS: honor legacy `messages.tts.providers.edge` voice settings after normalizing Edge TTS to the Microsoft provider. Fixes #64153.

- Voice-note targets such as Feishu and Telegram are transcoded from MiniMax

MP3 to 48kHz Opus with `ffmpeg`, because the Feishu/Lark file API only

accepts `file_type: "opus"` for native audio messages.

- MiniMax T2A accepts fractional `speed` and `vol`, but `pitch` is sent as an

integer; OpenClaw truncates fractional `pitch` values before the API request.

| Setting | Env var | Default | Description |

| ---------------------------------------- | ---------------------- | ----------------------------- | -------------------------------- |

| `messages.tts.providers.minimax.baseUrl` | `MINIMAX_API_HOST` | `https://api.minimax.io` | MiniMax T2A API host. |

| `messages.tts.providers.minimax.model` | `MINIMAX_TTS_MODEL` | `speech-2.8-hd` | TTS model id. |

| `messages.tts.providers.minimax.voiceId` | `MINIMAX_TTS_VOICE_ID` | `English_expressive_narrator` | Voice id used for speech output. |

| `messages.tts.providers.minimax.speed` | | `1.0` | Playback speed, `0.5..2.0`. |

| `messages.tts.providers.minimax.vol` | | `1.0` | Volume, `(0, 10]`. |

| `messages.tts.providers.minimax.pitch` | | `0` | Integer pitch shift, `-12..12`. |

### Music generation

- `providers.minimax.voiceId`: voice identifier (default `English_expressive_narrator`, env: `MINIMAX_TTS_VOICE_ID`).

- `providers.minimax.speed`: playback speed `0.5..2.0` (default 1.0).

- `providers.minimax.vol`: volume `(0, 10]` (default 1.0; must be greater than 0).

- `providers.minimax.pitch`: pitch shift `-12..12` (default 0).

- `providers.minimax.pitch`: integer pitch shift `-12..12` (default 0). Fractional values are truncated before calling MiniMax T2A because the API rejects non-integer pitch values.

- `providers.google.model`: Gemini TTS model (default `gemini-3.1-flash-tts-preview`).

- `providers.google.voiceName`: Gemini prebuilt voice name (default `Kore`; `voice` is also accepted).

- `providers.google.baseUrl`: override the Gemini API base URL. Only `https://generativelanguage.googleapis.com` is accepted.

- `model` (OpenAI TTS model, ElevenLabs model id, or MiniMax model) or `google_model` (Google TTS model)

- `stability`, `similarityBoost`, `style`, `speed`, `useSpeakerBoost`

- `vol` / `volume` (MiniMax volume, 0-10)

- `pitch` (MiniMax pitch, -12 to 12)

- `pitch` (MiniMax integer pitch, -12 to 12; fractional values are truncated before the MiniMax request)

- `applyTextNormalization` (`auto|on|off`)

- `languageCode` (ISO 639-1)

- `seed`
