Introduction to Apps to Support Users with Disabilities

Eliminate the anxiety of misunderstood speech with Mieru Call

This is an innovative service that converts the words of the other party in a telephone conversation into text in real time and displays them on the screen of your smartphone. It can be conveniently used by people who feel that it is difficult to understand the words of the other party when talking on the phone.
This service also makes it possible to send voice messages to others by simply inputting text. People with hearing impairments (such as being deaf or hard of hearing) and the elderly can conveniently use this service 24 hours a day.

  • Application must be made for test users to use the service during the trial period.
  • The accuracy of the text conversion may vary due to factors such as speaking manner and background noise.

Hearing-impaired user support app, KoeTra

KoeTra is an app that provides support to enable smooth communication between hearing-impaired users and non-hearing impaired users who cannot use sign language by converting text to voice and voice to text.
DOCOMO supports the KoeTra app to enable the smooth communication of people with disabilities and support their social lives.
