Description by Big O, LLC. Written by the developer, not by AppBrain. Click to read.
Keep the reference fresh in your ear while you listen to your own voice.
Three simple controls
• Play sound: listen to the American reference.
• Hold to record: speak while holding, then release to hear yourself immediately.
• Play both: hear the reference followed by your own recording.
Targeted phonetic sets
Explore 70 targeted phonetic sets, designed and brought together by a professor with 30 years of experience. Practice individual sounds, words and phrases with American Male or American Female reference recordings.
See what you hear
Compare labeled sound patterns, pauses, recording length, and the rise and fall of each voice on the main screen. These are listening guides, not an accent grade or a pronunciation score.
Build a practice habit
Return to saved recordings and listen for changes over time. Earn private pools and levels through completed practice rounds. Levels measure participation, not speech quality; there is no shared leaderboard.
Private, offline practice
No account is required. Voice recordings and practice history stay on your device. Review or delete your recordings in Settings.
