speakturbo - Talk to your Claude!
Give your agent the ability to speak to you real-time. Ultra-fast text-to-speech with ~90ms latency and 8 built-in voices.
Quick Start
Play immediately - you should hear "Hello world" through your speakers
speakturbo "Hello world"
Output: ⚡ 92ms → ▶ 93ms → ✓ 1245ms
Verify it's working by saving to file
speakturbo "Hello world" -o test.wav ls -lh test.wav # Should show ~50-100KB file
Output explained: ⚡ = first audio received, ▶ = playback started, ✓ = done
First Run
The first execution takes 2-5 seconds while the daemon starts and loads the model into memory. Subsequent calls are ~90ms to first sound.
First run (slow - daemon starting)
speakturbo "Starting up" # ~2-5 seconds
Second run (fast - daemon already running)
speakturbo "Now I'm fast" # ~90ms
Usage
Basic - plays immediately (default voice: alba)
speakturbo "Hello world"
Save to file (no audio playback)
speakturbo "Hello" -o output.wav
Save to specific file
speakturbo "Goodbye" -o goodbye.wav
Quiet mode (suppress status messages, still plays audio)
speakturbo "Hello" -q
List available voices

Text Input Encoding: UTF-8 Quotes in text: Use escaping: speakturbo "She said \"hello\"" Long text: Supported, streams as it generates Exit Codes Code Meaning 0 Success (audio played/saved) 1 Error (daemon connection failed, invalid args) When to Use
Use speakturbo when:
You need instant audio feedback (~90ms) Speed matters more than voice variety Built-in voices are sufficient
Use speak instead when:
You need custom voice cloning (Morgan Freeman, etc.) → speak "text" --voice ~/.chatter/voices/morgan_freeman.wav You need emotion tags like [laugh], [sigh] Quality/variety matters more than speed
See the speak skill documentation for full usage.
Troubleshooting
No audio plays:
Check daemon is running
curl http://127.0.0.1:7125/health
Expected:
Verify by saving to file and playing manually
speakturbo "test" -o /tmp/test.wav afplay /tmp/test.wav # macOS aplay /tmp/test.wav # Linux
Daemon won't start:
Check port availability
lsof -i :7125
Manually kill and restart
pkill -f "daemon_streaming" speakturbo "test" # Auto-restarts daemon
First run is slow: This is expected. The daemon needs to load the ~100MB model into memory. Subsequent calls will be fast (~90ms).
Daemon Management
The daemon auto-starts on first use and auto-shuts down after 1 hour idle.
Check status
curl http://127.0.0.1:7125/health
Manual stop
pkill -f "daemon_streaming"
