Why Let'sTalkSign?

According to WHO, as of Mar’19, around 466 million of the world's population have disabling hearing loss (~432 million adults and ~34 million children). It is estimated that by 2050 over 900 million people will have disabling hearing loss i.e. one in every ten people. Similarly as of 2018, roughly 100 million of the Indian population have some level of functional hearing loss.
Apart from those with hearing loss, people with speech loss or impairment also use sign language to communicate.


There are numerous challenges faced by deaf/hard of hearing people, like:

  • denial of their ‘right to education’ – in India education system is non-inclusive, neglecting people with hearing & visual disabilities
  • lack of schools for teaching sign languages
  • lack of job opportunities
  • social and workplace isolation – public & private offices, public places like hospitals, railways station, police station, etc. do not have mechanisms to communicate with hearing and speech impaired people
  • discrimination at workplace and public places
  • issues arising from lack of awareness by public about challenges of people with hearing and speech impairment

Indian Sign Language

To top all these challenges, in India while there are 20+ major languages, there is no officially recognized sign language system yet. Though Indian Sign Language (ISL) is considered as standard, there are a variety of sign languages used across the country with significant variations. As a result, 99% of deaf / hard of hearing people are either uneducated or drop out after Class VI or VII, because they are not able to cope. With no proper education, there is not much job opportunities for deaf/hard of hearing & speech impaired people.

Voice loss

Apart from people who are born with voice / speech disability, there are people who have lost their voice due some accident or disease like acute laryngitis, etc. and struggle to learn sign language and cope with demanding life.

10% of India's population have some level of functional hearing loss
