Make Python Talk, Make Python Listen
summary
Covers concrete code and limits: PyTTSx3 uses the OS speech engine, requires engine.init then say and run_and_wait and can save WAV via save_to_file; gTTS downloads Google Translate audio and needs internet. Whisper runs offline after model download, the base model transcribes to punctuated text and can emit timestamped subtitles for search. yt-dlp fetches videos for transcription. OCR requires Tesseract installed and pytesseract.image_to_string, works best on scanned typewritten pages not photos or handwriting and often needs Pillow/OpenCV preprocessing; Raspberry Pi deployment and mass‑surveillance risks are demonstrated.
