New Features: - AssemblyAI backend with automatic speaker labeling - Backend switching UI via C-; T b (completing-read interface) - Universal speech model supporting 99 languages - API key management through auth-source/authinfo.gpg Implementation: - Created scripts/assemblyai-transcribe (upload → poll → format workflow) - Updated transcription-config.el with multi-backend support - Added cj/--get-assemblyai-api-key for secure credential retrieval - Refactored process environment handling from if to pcase - Added cj/transcription-switch-backend interactive command Testing: - Created test-transcription-config--transcription-script-path.el - 5 unit tests covering all 3 backends (100% passing) - Followed quality-engineer.org guidelines (test pure functions only) - Investigated 18 test failures: documented cleanup in todo.org Files Modified: - modules/transcription-config.el - Multi-backend support and UI - scripts/assemblyai-transcribe - NEW: AssemblyAI integration script - tests/test-transcription-config--transcription-script-path.el - NEW - todo.org - Added test cleanup task (Method 3, priority C) - docs/NOTES.org - Comprehensive session notes added Successfully tested with 33KB and 4.1MB audio files (3s and 9s processing). 2025-11-04T20:40:20+00:00 Craig Jennings c@cjennings.net 2025-11-04T20:40:20+00:00 urn:sha1:99d7be95a0306a9b1fa0577c2751a452636b193b Changed transcription submenu keybindings: - C-; t t → C-; t a (transcribe audio) - C-; t b → C-; t v (view transcriptions) - C-; t k → unchanged (kill transcription) More intuitive mnemonics: a=audio, v=view, k=kill 2025-11-04T20:35:50+00:00 Craig Jennings c@cjennings.net 2025-11-04T20:35:50+00:00 urn:sha1:d9bcfaa1d4924897a313499c4ce6821e32e53d5b Implemented full transcription system with local Whisper and OpenAI API support. Includes comprehensive test suite (60 tests) and reorganized keybindings for better discoverability. Features: - Async transcription (non-blocking workflow) - Desktop notifications (started/complete/error) - Output: audio.txt (transcript) + audio.log (process logs) - Modeline integration showing active transcription count - Dired integration (press T on audio files) - Process management and tracking Scripts: - install-whisper.sh: Install Whisper via AUR or pip - uninstall-whisper.sh: Clean removal with cache cleanup - local-whisper: Offline transcription using installed Whisper - oai-transcribe: Cloud transcription via OpenAI API Tests (60 passing): - Audio file detection (16 tests) - Path generation logic (11 tests) - Log cleanup behavior (5 tests) - Duration formatting (9 tests) - Active counter & modeline (11 tests) - Integration workflows (8 tests) Keybindings: - Reorganized gcal to C-; g submenu (s/t/r/c) - Added C-; t transcription submenu (t/b/k) - Dired: T to transcribe file at point
