⚙️ Configuration

No configuration needed! The skill automatically:

• Detects Faster-Whisper or Whisper installation
• Chooses the fastest available engine
• Selects appropriate model based on file size
• Auto-detects language

🔧 Troubleshooting

"No transcription tool found"

Solution: Install Whisper:

pip install faster-whisper

"Unsupported format"

Solution: Install ffmpeg:

brew install ffmpeg  # macOS
apt install ffmpeg   # Linux

Slow processing

Solution: Use a smaller Whisper model:

# Edit the skill to use "tiny" or "base" model instead of "medium"

Poor speaker identification

Solution:

• Ensure clear audio with minimal background noise
• Use a better microphone for recordings
• Try the "medium" or "large" Whisper model

🛠️ Advanced Usage

Custom Model Selection

Edit SKILL.md Step 2 to change model:

model = WhisperModel("small", device="cpu")  # Change "base" to "small", "medium", etc.

Output Language Control

Force output in specific language:

# Edit Step 3 to set language explicitly

Batch Settings

Process specific file types only:

copilot> transcribe audio: recordings/*.wav  # Only WAV files

📚 FAQ
