Implementation Reference

• windows_tts_mcp/main.py:229-253 (handler)

  The speak_slow tool handler function. Registered via @mcp.tool() decorator. Splits text into chunks, speaks each slowly (rate=-3) in a background thread using powershell_tts.

  @mcp.tool()
  def speak_slow(text: str) -> str:
      """텍스트를 천천히 읽어줍니다"""
      try:
          # 텍스트 분할
          text_chunks = split_text_for_tts(text, 400)
          total_chunks = len(text_chunks)
          
          def _speak_slow():
              for i, chunk in enumerate(text_chunks, 1):
                  safe_print(f"[SLOW TTS] {i}/{total_chunks} 부분 재생 중: {chunk[:50]}...")
                  powershell_tts(chunk, rate=-3, volume=100)  # 느린 속도
                  if i < total_chunks:
                      time.sleep(0.8)  # 느린 재생은 간격을 더 길게
          
          thread = threading.Thread(target=_speak_slow, daemon=True)
          thread.start()
          
          if total_chunks > 1:
              return f"[SLOW] 천천히 재생 시작 ({total_chunks}개 부분): '{text[:50]}...'"
          else:
              return f"[SLOW] 천천히 재생 시작: '{text[:50]}...'"
          
      except Exception as e:

• windows_tts_mcp/main.py:67-129 (helper)

  Core helper function that executes TTS via PowerShell, managing processes and supporting rate/volume parameters. Used by speak_slow.
