# homeai-voice/setup.sh — P3: Voice pipeline (STT / TTS / Wyoming)
#
# Components:
#   - Whisper.cpp         — speech-to-text (Apple Silicon / CUDA optimised)
#   - wyoming-faster-whisper — Wyoming STT adapter (port 10300)
#   - Kokoro TTS          — fast text-to-speech via ONNX
#   - wyoming-kokoro      — Wyoming TTS adapter (port 10301)
#   - Chatterbox TTS      — voice cloning (MPS / CUDA)
#   - openWakeWord        — always-on wake word detection
#
# Prerequisites:
#   - P1 (homeai-infra) completed — Home Assistant running
#   - P2 (homeai-llm) completed  — Ollama running
#   - Python 3.10+ installed
#   - macOS: Xcode Command Line Tools (for whisper.cpp compilation)
#   - Linux: build-essential, cmake
