EchoGap: Speaking Practice

EchoGap turns any audio recording into sentence-by-sentence speaking practice — for whatever language you're learning. Drop in an audio file — a podcast, an audiobook chapter, a lesson recording — and EchoGap automatically finds the silences between sentences and splits it into segments you can tap, replay, and practice with. WHAT YOU CAN DO • Automatic sentence segmentation — silence-based detection splits your audio into individual sentences, no manual editing required. • Repeating — listen to a segment, then repeat it back during a silent pause sized to give you time to speak. A countdown ring shows how much time is left. • Tap any segment to replay it instantly, at any speed from 0.5x to 2.0x. • Organize your audio into playlists and pick up right where you left off. • Keep practicing hands-free — control playback from the lock screen and notification shade, even with the screen off. • Track your practice — daily minutes, repeat counts, and streaks (Premium). SIX WAYS TO PRACTICE EchoGap fits six well-known speaking and listening methods: • Shadowing — speak along a beat behind the audio, without looking at a script. • Overlapping — read your own script while speaking in exact sync with the audio. • Repeating — listen, then repeat what you heard during the silent pause. • Reproduction — listen, then reproduce the sentence from your own understanding and memory. • Dictation — replay a segment as many times as you need and write down what you hear. • Read-aloud — read a script you understand aloud, using the audio to check pronunciation and pace (bring your own script — the app doesn't display text). PREMIUM The free version has no limit on Repeating, waveform display, sentence segmentation, playback speed, or track looping — only playlist count (2), tracks per playlist (5), and theme color are limited. Premium removes those limits and unlocks your practice history. PRIVACY All processing happens on your device. Your audio is never uploaded anywhere. Works on iPhone and iPad (iOS 15.0+).
