TalkMirror: Your Private Instant Voice Mirror Speak, pause naturally, and hear your voice right away. TalkMirror helps you notice pronunciation, pacing, rhythm, and clarity while the moment is still fresh. CHOOSE HOW YOU WANT TO PRACTICE • Free speaking: use instant playback like an acoustic mirror. • Today's shadowing: pick an optional prompt and compare it with a reference voice. • Rehearse: prepare a presentation, interview, speech, or script at your own pace. THREE FREE PRACTICE TOOLS Mode 1 — Voice Mirror Hear each phrase immediately after you pause. Mode 2 — Shadowing Choose from 100 built-in English prompts or paste your own script. Practice line by line: hear your voice first, then the reference voice. Mode 3 — Stage Pacing Time-box a presentation with checkpoints, or use Breath Density cues with Auto and levels 1–10 to shape pacing and pauses. Make it yours with five themes: Default, Paper & Ink, Pixel Arcade, Spotlight and Night Radio. Each one restyles all three modes—an ink drop that spreads as you speak, a pixel companion that talks along, a stage spotlight or a glowing VU meter—on iPhone and iPad. PRIVATE BY DESIGN • Audio is processed in memory for immediate playback. • Raw recordings are never stored on disk. • Audio is never uploaded to a server. • The microphone stops in the background or when the screen locks. • Recording never resumes without your action. All core modes and the built-in practice library are free. There are no subscriptions, ads, accounts, or locked practice features.
