SeeSoundLive

See Sound Live is a speech-development initiative from 4S Medical Research P Ltd, created to give deaf people an additional way to communicate with people who do not know sign language. The service recognizes sign languages as essential communication tools while addressing a challenge in spoken-speech learning: without auditory feedback, learners may have difficulty knowing whether they are producing sounds correctly.

See Sound Live uses visual feedback to support practice. When a user speaks, the application displays a vivid color pattern representing the sound. Different sounds produce different patterns, while repeated sounds retain the same pattern, helping learners observe and adjust their attempts. Learning can begin with simple sounds such as “aa,” “ee,” and “oo,” then progress toward spoken sounds and words such as “Mama,” “Papa,” “Hello,” and “Bye.”

The brand offers two applications: Voca Spectrum 3D, available for Windows and Android, and Voca Spectrum, available for Windows, Android, and iOS. See Sound Live also provides learning guidance, a sounds library, FAQs, and contact information.
