Tell us about your day, describe your work, anything — just keep talking. The app will learn your unique voice pitch to filter out coworkers.

Everyone's voice has a characteristic pitch (F0) — men typically 85–155 Hz, women 165–255 Hz. After enrollment, ClearVoice knows your range and applies extra suppression when it detects a voice at a different pitch (coworker, nearby TV, etc.).
