Echo

Listen to each sentence, then record yourself saying it. Play them back side by side to compare rhythm and cadence.

Microphone access needed

Tap any "Record" button below and allow microphone access when your browser asks. On iPhone this must be over HTTPS.

Native audio is generated with your device's built-in speech voice for this test version — real recorded/AI voice audio comes next. Recordings stay in this browser tab only; nothing is uploaded. On iPhone/iPad, make sure the ringer switch isn't set to silent — Safari mutes page audio when it is.
