How it works

One verse. Four layers. And it plays.

Press play, switch the layers on and turn the voice down to sing along. This is FonoBeat from the inside.

FonoBeat app, Sing screen: the lyrics of a song in Spanish with, under each line, its translation, how to say it and the IPA.

Hear the four layers

Four layers, in the same order as the app: the lyrics, their translation, the sounds-like line and the phonetic alphabet. Switch them on and off to see what each one adds.

Layers on

In the app this choice is saved per profile: each child sees the layers they need, and can remove them as they gain confidence.

  1. Hello! Hello!

A real excerpt from “What Is Your Name?”: 33 s of a 1:52 song. The voice and the backing track are two separate files —the same ones the app uses— 256 KB each, and nothing downloads until you press play.

How it works

One song, four moments

  1. Listen

    The song plays and the lyrics light up word by word, in sync with the music.

  2. Read

    Up to four layers on screen: the lyrics, what they mean, how to say them with your own letters and how they sound in the phonetic alphabet. The helps switch on or off with a tap; the lyrics stay.

  3. Pronounce

    Your child turns the singer down and takes that part themselves. The feedback celebrates the attempt — there are never any red marks.

  4. Progress

    Every session adds practice days, minutes, finished songs and new words, and you can see it in the parent dashboard.

And when they stop reading and start singing

  • The voice goes down, it does not go off

    A slider mixes the vocal track with the instrumental one. The guide voice can start loud and come down when the child feels ready, until only the music is left.

  • The feedback celebrates the attempt

    When they sing a Challenge, the app listens and gives back a kind comment about which sound to move closer. The child’s audio is processed and discarded: it is never stored, not on the phone and not on a server.

  • The word comes back, in another song

    Each word reappears on average in 8.7 later lessons, in another world and with another melody. It is the boring part of learning a language, done with different songs.
