openclaw - 💡(How to fix) Fix feat(tts): xiaomi voicedesign/voiceclone model support

Problem

The Xiaomi TTS provider only supports mimo-v2.5-tts and mimo-v2-tts in XIAOMI_TTS_MODELS. The newer mimo-v2.5-tts-voicedesign and mimo-v2.5-tts-voiceclone models are not recognized, so they cannot be selected via config.

Additionally, the voicedesign and voiceclone models do not accept a voice parameter in the audio field — passing it returns HTTP 400 Param Incorrect. The current xiaomiTTS function always includes voice in the request body regardless of model.

Affected file

dist/speech-provider-Cc3hcgqu.js

Reproduction

Set messages.tts.providers.xiaomi.model to mimo-v2.5-tts-voicedesign in openclaw.json. TTS fails silently (model not in list) or returns 400 if the model somehow reaches the API with a voice field.

Fix

1. Extend XIAOMI_TTS_MODELS:

// before
const XIAOMI_TTS_MODELS = ["mimo-v2.5-tts", "mimo-v2-tts"];

// after
const XIAOMI_TTS_MODELS = ["mimo-v2.5-tts", "mimo-v2-tts", "mimo-v2.5-tts-voicedesign", "mimo-v2.5-tts-voiceclone"];

2. Conditionally omit voice for voicedesign/voiceclone:

// before
audio: {
    format,
    voice
}

// after
audio: {
    format,
    ...(model.includes("voicedesign") || model.includes("voiceclone") ? {} : { voice })
}
