• windows_tts_mcp/main.py:255-279 (handler)

  The primary handler for the 'speak_quiet' tool. Decorated with @mcp.tool() for automatic registration in FastMCP. Splits long text into chunks using split_text_for_tts, executes TTS playback in a background thread using a nested _speak_quiet helper that calls powershell_tts with volume=50 for quiet speech, and returns a status message.
  @mcp.tool() def speak_quiet(text: str) -> str: """텍스트를 작은 볼륨으로 읽어줍니다""" try: # 텍스트 분할 text_chunks = split_text_for_tts(text, 400) total_chunks = len(text_chunks) def _speak_quiet(): for i, chunk in enumerate(text_chunks, 1): safe_print(f"[QUIET TTS] {i}/{total_chunks} 부분 재생 중: {chunk[:50]}...") powershell_tts(chunk, rate=0, volume=50) # 작은 볼륨 if i < total_chunks: time.sleep(0.5) thread = threading.Thread(target=_speak_quiet, daemon=True) thread.start() if total_chunks > 1: return f"[QUIET] 작은 볼륨 재생 시작 ({total_chunks}개 부분): '{text[:50]}...'" else: return f"[QUIET] 작은 볼륨 재생 시작: '{text[:50]}...'" except Exception as e: return f"[ERROR] 작은 볼륨 재생 오류: {str(e)}"

  Core helper function that executes TTS via PowerShell with configurable rate and volume. Called by speak_quiet with rate=0, volume=50 to produce quiet speech. Handles process management, text escaping, and error handling.

  Helper function to split long text into TTS-friendly chunks (max 500 chars by default, 400 for speak_quiet). Ensures natural sentence boundaries for smooth playback. Used by speak_quiet.
