The space between two sounds is where voicing continuity is most fragile — and where it can be practiced. Sound Bridge measures every transition you make, in real time.
Every transition resolves through the same three phases. The way it breaks tells you something different each time. Press play. Watch what the engine sees.
Sound Bridge runs on the DFS engine that powers the FluentPlay platform. Frame-accurate, microphone-only, no wearables. Every attempt measured.
Four acoustic states — voiced, breath, building, silent — classified every 16 ms. Fricatives, stops, and sustained voicing each carry their own signature. The engine knows which.
Pitch traced where voicing exists, energy envelope traced everywhere else. Continuity through the slide is the clearest visible signature of a smooth transition, mapped frame-by-frame.
Hold. Slide. Land. Each of the three phases scores independently against the engine — so the data tells you which moment of the bridge needs the next minute of practice.
Sound Bridge is part of the FluentPlay suite — engineered around real speech-motor mechanics, with a measurement engine that runs underneath every game.
