Real-time feedback, completely private
Speak Slower uses a high-performance DSP engine built in Rust that runs entirely on your device. It detects syllables using signal processing — no speech-to-text, no AI transcription, no cloud servers. Your voice never leaves your phone.

Everything you need to master your speaking pace
See your speaking pace measured in syllables per second, updated in real time as you talk. Instant visual feedback helps you self-correct.
The app can distinguish your voice from background noise and other speakers, so it only measures your pace — not the room's.
Built on published research (de Jong & Wempe 2009), the engine uses bandpass filtering, intensity analysis, and peak detection — not AI guesswork.
No recordings are stored. No audio leaves your device. No accounts needed. The microphone stream is processed in real time and immediately discarded.
Anyone who wants to speak more clearly
Practice presentations and speeches with real-time pace feedback. Train yourself to maintain an engaging, measured delivery.
Monitor your pace while practicing a new language. Speaking slower helps with pronunciation, clarity, and listener comprehension.
Whether in meetings, interviews, or phone calls — knowing your pace helps you communicate with more clarity and confidence.
