It is very difficult for these people to express during emergency situations like when they are attacked or need medical assistance. The devices available for the convenience of their communication are generally very expensive and unaffordable for the underprivileged people.

This talking assistance device for people who cannot speak will guide them whenever they will travel alone and need to communicate with other people. The device has been locally developed in order to promote local innovation and utilization of in-house local expertise. The device is the lowest price in the national and international market.

The device is so affordable that any developing or least developing countries can also avail this easily.
