Tone quality doesn't change even if the reproduction speed is changed. "C-TST" development x of tone quality that controlled the reproduction speed without changing it was done.

Tone quality changes when the voice changes the reproduction speed. There are a lot of people who experienced in Mawa and special software such a phenomenon early of the tape. There are a lot a content of the conversation fast and without catching easily, and canceling for the game progress though I want to listen to "The voice" by the scene about which the radio actor talks. There is play of making it listen by using that tone quality changes oppositely at the reproduction speed like the another person, and modeling it on the voice of a famous person, too.

After deterioration in tone quality is suppressed as much as possible, the reproduction speed can be changed in the technology of "C-TST" developed this time. No "The speed of the title is made fast and the voice skip", and "The voice is hastened according to the speed of the title" are possible when there is a scene about which the radio actor talks for instance on title (telop) assistant's screen in the game if this technology is used. In a word, it comes to be able to offer choices "Even the person who wants to play the game quickly can enjoy radio actor's voice (As such,)". It can enjoy the voice without the sense of incompatibility because it doesn't become the current shrill even if the speed is made fast.

The reproduction speed transmutable hardly changing tone quality is a range of the plus or minus 30% according to release. It is possible to reproduce within the ranges of 7-13 seconds in case of the number of seconds. Moreover, because it is possible to change real-time and freely, the reproduction speed can be besides high-speed only a specific phrase slowly. Of course, it is possible by not only Japanese but also the other language like English etc.

Concrete sampling data can be auditioned in [the introduction page]. The tone quality change that occurs certainly by the speed change of the past doesn't occur if it actually listens. It is possible to catch it almost at former voice and the understanding level.

This technology uses it exclusively for the development section of NINTENDO DS. A general person cannot use it. The voice output software (Educational system and brain tray system might) for DS that uses this technology is sure to appear sooner or later. However, the tool that looks very profitable for the person who is offering data by the voice for instance on the blog and the site (For instance, the course and news, etc. are served as a Pod casting) is true. The one that it wants making in the future to marketing some shape to use it excluding the development department bureau to be examined.
