Summary

Support multiple languages for speech recognition and TTS output.

Requirements

  • Whisper multi-lang: Switch Whisper STT model language (en/fr/es/de/ja/zh) via ROS2 param
  • TTS voices: Per-language Piper voice models, hot-swappable
  • Auto-detect: Detect spoken language from Whisper output, auto-switch TTS
  • Translation: Optional on-device translation between languages (e.g., user speaks French, bot responds in French)
  • LLM context: Pass detected language to conversation engine for language-appropriate responses
  • ROS2 params: /social/language (current), /social/language/available (list)
  • Voice-triggered: 'Speak French', 'Switch to English' voice commands
