Italian Run (Speed Drill)
Build muscle memory by running your lines at 1.5–2× speed with zero pauses.
Overview
An Italian Run is a traditional theatre rehearsal technique where actors deliver their lines as fast as possible, eliminating pauses and hesitations. On Book Rehearsal brings this technique to solo practice with an AI partner that fires cues at accelerated speed.
How It Works
- Select your scene and character on the setup screen
- Choose Italian Run as your rehearsal mode
- Tap Go to start the countdown timer
- The AI reads cue lines at 1.5–2× normal speed
- Deliver your lines immediately — no thinking time
- The session continues until the timer expires or the scene ends
The AI uses zero-latency turn-taking: the moment you finish your line, the next cue fires instantly. There are no pauses, no corrections, and no do-overs — just pure speed.
The Countdown Timer
Italian Run sessions are timed. A visible countdown timer appears on screen:
- Default duration: 3 minutes
- The session automatically ends when the timer reaches zero
- You can also stop the session manually at any time
Short, Intense Bursts
Italian Runs are designed to be short and intense. Multiple quick sessions are more effective than one long one for building speed and automaticity.
No Corrections
Unlike Voice Rehearsal, the AI does not stop to correct mistakes during an Italian Run. The strictness level has no effect on this mode — it's purely about speed and flow.
If you need accuracy feedback, use Voice Rehearsal or Flashcard Mode instead.
When to Use Italian Runs
| Stage of Rehearsal | Recommendation |
|---|---|
| Early (still learning lines) | Start with Flashcard Mode or Voice Rehearsal first |
| Mid (lines mostly memorized) | ✅ Begin incorporating Italian Runs to build speed |
| Late (performance-ready) | ✅ Use daily to maintain sharpness and eliminate "thinking pauses" |
Subscription Requirements
Italian Run uses the same voice technology as Voice Rehearsal and requires:
- Voice Pro subscription (in-app purchase), or
- Active production membership via On Book Pro
Troubleshooting
| Problem | Solution |
|---|---|
| AI doesn't hear me | Check microphone permissions |
| Session ends immediately | The countdown timer may be set too short — check your session settings |
| Audio quality is poor | Ensure a stable internet connection; use headphones to avoid echo |
