NTT DoCoMo is planning on releasing a mobile phone able to slow down speakers' voice speed.  The key targeted users are the elderly. 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. Screen visibility is improved by a semi-transmissive LCD panel called an "all-round LCD." 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. If users input their body weight and length of stride, the handset calculates walking distance and energy consumption.
