Speech Development in the Deaf
Sign languages have been the native language for deaf communities across the world and are an important tool for expressive and receptive communication for the user. However, as with any other language, the communication is limited to users of the sign language. See Sound Live started as an idea to provide an additional channel of communication for the deaf, and bridging the communication divide they face when engaging with those who do not know how to sign.
With See Sound Live, a deaf person can learn to speak by harnessing their heightened visual senses. They can start by speaking simple sounds like “aa”, “ee”, “oo”, and then eventually speak out bigger sounds and words. With regular learning and practice, a deaf person can build a vocabulary of spoken sounds and words like Mama, Papa, Hello, Bye, and more!
How it works
Feedback is the most important aspect of learning anything – it is how we know to ‘course-correct’, and what to change to get it right. This applies to speaking as well. A deaf person may be capable of producing sounds. But when they try to speak, they are not able to get the auditory feedback, and so they don’t know if they are making the right sounds. This missing feedback stops them from developing clear speech.
See Sound Live provides this feedback via visual cues. When a deaf person tries to speak, the application creates a visual equivalent for the sound, seen as a pattern of vivid colors. These patterns are markedly different for a different sound and remain the same if the same sound is repeated. So, the brain is getting this valuable feedback on the spoken sound – but instead of the ear, it is through the eyes!
