The collaboration hopes to expand upon the communication features on Nintendo systems.
Japanese communications company NTT is working with Nintendo on developing speech recognition software, NHK recently reported.
NTT developed software for the DS that can convert voices into text. The hope is that it would help children with disabled students do better in school.
Nintendo supplied the DS units. The teacher's voice is converted by NTT's software into words that will be displayed on the device's screen.
