python - Raspberry Pi でこのプログラムを実行する方法

Question

Windows用のこのpythonプログラムを作成しました。ラズベリーパイの実行を手伝ってください。コマンドを認識し、それに応じてタスクを返信するボイスチャットボットプログラムです。Windows python IDE では問題なく動作しますが、残念ながら Raspberry Pi では応答しません。この問題を解決して、このプログラムを Raspberry 4 で実行する方法を教えてください。

この行のエラー:

engine = pyttsx3.init('sapi5') voices = engine.getProperty('voices') 
# print(voices[1].id) engine.setProperty('voice', voices[0].id)
