Samsung's Impulse turns speech into taps so stutterers can speak

Rhythm-based speech therapy is effective for people who stutter, but it normally has to happen in a clinic with a therapist, so it is limited and expensive.

Cheil Spain and Samsung built Impulse, a Galaxy Watch app that uses natural-language processing to read the wearer's speech and convert it into rhythmic haptic vibrations — an invisible, inaudible assistant that keeps the timing cue with the person wherever they are.

A 'training mode' adds custom speech exercises, so the device covers both the live assistance and the practice, taking a proven clinical technique out of the clinic without requiring the user to know anything technical.

Move therapy into a watch that keeps the rhythm on you

It embeds the timing cue in a device the user already owns and wears.

Haptics are invisible and inaudible, so the cue doesn't draw attention.

It shifts therapy from a visit to a constant companion, improving convenience.

It turns a health treatment into a consumer product Samsung can ship at scale.

If a proven therapy is inaccessible because it is tied to a place, transplant its core mechanism into a device people already wear.

Impulse won three Lions at Cannes 2024, including a Gold in Design, for the use of AI and haptics to help people with speech disorders. It demonstrated that accessibility improvements can be product innovations rather than separate charity devices, opening a path to wider adoption of wearable-assisted speech therapy.
