The speed converter technology slows down speakers’ voice speed up to 0.7x, so the listener can feel like that the speakers’ dialogue goes slowly. The technology does not slow down the voice part, but shortens the part without sound between phrases. When a time lag between the original voice and the converted voice exceeds one second, the function automatically stops.
DoCoMo also prepared a main menu screen exclusively designed for the handset. By reducing the number of menu items as well as using relatively large icons, screen operation became easier than before.
Other functions include a system to start an emergency alarm of about 80 dB and a pedometer.
