Audio & AI Setup
Configure your microphone, scroll method, language, and tuning parameters for the teleprompter.
Scroll Method
VoxiPrompter offers two ways to advance your script. Choose the one that fits your workflow — you can switch between them at any time.
AI Voice Tracking
Listens to your microphone and matches spoken words to the script in real time. The cursor follows your voice automatically.
Auto-Scroll
Advances the script at a constant speed you control (1x–10x). No microphone needed — ideal for rehearsals or pre-recorded content.
Only one scroll mode can be active at a time. Starting one automatically stops the other.
AI Voice Tracking Mode
When "AI" is selected as the scroll method, the panel shows microphone input, language, Speaking Pace, and script matching tuning.

Auto-Scroll Mode
When "Auto-Scroll" is selected, the panel simplifies — no microphone, language, or AI tuning. Just a speed slider.

Auto-Scroll Speed
No microphone is needed in auto-scroll mode. The script advances at a steady pace. Press Space to start or pause.
Input Device
Select which microphone the app listens to. The dropdown lists all available input devices on your system. This section only applies to AI Voice Tracking mode.
- Microphone — choose from the dropdown. The default device is pre-selected on first launch.
- Refresh — click if you plugged in a new microphone and it doesn't appear in the list.
- Mic Level — real-time meter showing audio input strength. Speak at normal volume and check that the bar moves.
- If no microphones are found, you'll see a permission prompt. See the FAQ for platform-specific permission instructions.
Language
Choose the language you'll be speaking. The AI model uses this to optimise transcription accuracy. Only applies to AI Voice Tracking mode.
The language setting is saved automatically. Changing it takes effect on the next listening session.
Speaking Pace
Speaking Pace is the single control that tunes the entire voice engine to your natural delivery speed. Only applies to AI Voice Tracking mode. Select the preset that best matches how you speak.
Fast (default)
For rapid, energetic presenters. Tightens endpoint timing so the engine keeps up with quick delivery.
Normal
Balanced timing for most speakers. Works well for conversational or rehearsed delivery at a natural pace.
Slow
For deliberate, methodical speakers or those with long pauses between sentences.
Auto-Scroll
Auto-scroll advances the script at a constant speed without listening to your voice. Switch from "AI" to "Auto" in the Scroll Method card to activate it.
How to activate
Click the "Auto-Scroll" button in the Scroll Method card. The panel simplifies to show only the speed control. The teleprompter begins advancing when you press Start or Space.
Speed control
Use the speed slider (1x–10x) to adjust how fast the script advances. You can change speed while auto-scroll is running — the change takes effect immediately.
No microphone needed
Auto-scroll does not use the microphone at all. The Input Device, Language, Speaking Pace, and Script Tracking cards are hidden when auto-scroll is active.
Where it works
Auto-scroll is available on the main window, mobile remote, and OBS dock. All surfaces share the same speed setting.
Text Matching Tuning
These sliders control how the AI matches your spoken words to the script. Found in the "Script Tracking" card of the Audio & AI Setup panel. Only applies to AI Voice Tracking mode.
Accuracy Threshold
The minimum confidence score required for a match to advance the cursor. Lower = more responsive but may match incorrectly. Higher = stricter, requires a closer word match.
Range: 10–90%. Default: 40%. Lower this if the prompter doesn't advance; raise it if it jumps to the wrong position.
Look Ahead
How many words ahead of the current cursor position the engine searches for a match. Larger = more forgiving if you skip a sentence or jump ahead in your script.
Range: 5–100 words. Default: 45.
Look Behind
How many words behind the current cursor position the engine searches. Useful when you repeat a line or go back to correct yourself.
Range: 0–100 words. Default: 50. Set to 0 if you never go back.
Troubleshooting
Prompter doesn't advance (AI mode)
Make sure your microphone is selected correctly, lower the Accuracy Threshold (try 20–30%), increase Look Ahead, and try the Fast Speaking Pace.
Prompter jumps to wrong position (AI mode)
Raise the Accuracy Threshold to 50–60% and reduce Look Ahead to 15–25 words. This makes matching stricter.
Cursor gets cut off mid-sentence (AI mode)
Switch Speaking Pace to Slow. This extends endpoint timing and increases the silence suppression cap, so the engine waits longer before closing a speech segment.
Prompter lags behind fast delivery (AI mode)
Switch Speaking Pace to Fast. This tightens all timing parameters so the engine finalises segments sooner.
Auto-scroll too fast or too slow
Adjust the speed slider in real time. The change applies immediately — no need to stop and restart.
Reset everything
Click Reset Config at the bottom of the Audio & AI Setup panel to restore all defaults.
Understanding the Status Bar
The header bar gives you real-time feedback on the current state of the teleprompter.
Live confidence percentage
During AI voice tracking, the header shows a live confidence percentage (e.g. "72%") indicating how well the AI is matching your speech to the script.
Status pill colors
The status pill changes color to reflect the current state: green when idle or ready, indigo when actively listening or auto-scrolling, and red when an error has occurred.
Error history panel
If errors occur, click the status area to expand the error history panel. It shows recent errors with timestamps, which is helpful for diagnosing intermittent issues.
Log Files and Diagnostics
If you need to report a bug or diagnose an issue, VoxiPrompter keeps a detailed log file you can access directly from the app.
Opening the log file
Click Open Log File in the sidebar footer. This opens the app.log file in your system's file explorer.
What the log contains
The log records startup information, errors, and state transitions. It provides a chronological record of what happened in the app.
Attaching logs when contacting support
When contacting support, attach the log file. This helps the team diagnose your issue much faster.
