Real speech · your voice · a little melody
Listen. Repeat.
Match the melody.
You can know every word and still miss the music. Hear a real speaker, repeat the phrase, and see how the rise and fall of your voice compares.
Free, open source, and right in your browser.
01 / From your ears to your voice
A real person. A real phrase. Listen before the words appear, so your ears get the first turn.
Record what you heard. Your voice makes its own line: the melody you actually spoke.
Look at the two contours. Hear the reference and yourself in turn. Notice a difference? Record again.
Each line is normalized to its speaker’s own pitch range and to the phrase’s duration. You’re comparing the shape, not whose voice is higher. No score. No “correct” voice.
Captured from the working app, without interface edits. The Record view uses a test microphone; no learner results are simulated.

02 / The idea began as a fable
Echo could repeat the words. But she had lost their music. Then a collector of cadences offered her something stranger than a new voice: a way to find her own.
“You must learn the shape of the pitch, and then pour your own life into it.”
A story of Echo, DaCo Mozzie, and the Cadence Sphere.

The demo uses 34 selected recordings from Common Voice Spontaneous Speech 4.0 – English, available through Mozilla Data Collective: 17 UK and 17 US clips.
People contributed their voices. Echos turns those real, spontaneous phrases into an opportunity to listen, notice, and practise.

04 / Your browser. Your practice.
The app estimates pitch and draws both contours in your browser. It does not upload your recording or send it to a speech-to-text service. Your take is held temporarily, not saved as an account or a score.
The live demo needs microphone permission to record, and HTTPS or localhost. Local processing is a design choice, not a blanket security guarantee; use a browser and device you trust.
No score to chase. A pattern to notice.
