📄 Description

Summary

Adds ModelsLab as a new TTS provider for AnythingLLM, following the exact same integration pattern as the existing ElevenLabs, OpenAI, and OpenAI-compatible TTS providers.

Changes

File Change
server/utils/TextToSpeech/modelsLab/index.js New ModelsLabTTS class
server/utils/TextToSpeech/index.js Add modelslab case to dispatcher
server/models/systemSettings.js Add TTSModelsLabKey/VoiceModel settings
server/utils/helpers/updateENV.js Env var handlers + provider registration

docker/.env.example Same env vars

Features

  • 10 voices: Bella, Antoni, Elli, Josh, Arnold, Adam, Sam, Rachel, Domi, Gigi
  • Async polling: handles status: "processing" responses (polls every 5s, up to 5 min)
  • 2,500-char limit: enforced automatically per ModelsLab API constraints
  • No new dependencies: uses existing node-fetch

Usage

TTS_PROVIDER=modelslab
TTS_MODELSLAB_KEY=your_api_key
TTS_MODELSLAB_VOICE_MODEL=Bella  # optional, defaults to Bella

Or configure via the AnythingLLM Settings > Audio Preferences UI.
