SOUND BRIDGE

Glide between sounds without breaking your voice

This game gives you two sounds and asks you to connect them without stopping your voice. You'll hold the first sound, smoothly slide into the second, and hold that one too — building a bridge of continuous voice between them.

hold "S"
sustain it
slide
don't stop!
hold "TH"
land it

The progress bar stretches to show which phase you're in. If your voice drops, the bridge breaks and you try again. The game scores how smooth your transition was and how well you held each sound.

Start with easy pairs like AH→M or EE→N. These have big differences between the sounds, so your voice naturally carries across. Harder pairs like S→TH are similar-sounding and require more precise control.
