  • Patent number: 9215748
    Abstract: In a system that performs communication between master and slave, the device better suited as the master device is not always the master device, since the device that initially constructs the network becomes the master device. A device that enters the network later transmits a restart request on detecting the master device, and if a restart permission is received, the device transfers to a restart state and transmits a master inquiry before the device that was the master device up until that point. Thus, a device that newly enters a network is able to operate as the master device even if a master device already exists in the network.

  • Patent number: 7162417
    Abstract: An amplitude altering magnification (r) applied to sub-phoneme units of a voiced portion and an amplitude altering magnification s to be applied to sub-phoneme units of an unvoiced portion are determined based upon a target phoneme average power (p0) of synthesized speech and power (p) of a selected phoneme unit. Sub-phoneme units are extracted from a phoneme to be synthesized. From among the extracted sub-phoneme units, a sub-phoneme unit of the voiced portion is multiplied by the amplitude altering magnification (r), and a sub-phoneme unit of the unvoiced portion is multiplied by the amplitude altering magnification (s). Synthesized speech is obtained using the sub-phoneme units thus obtained. This makes it possible to realize power control in which any decline in the quality of synthesized speech is reduced.

  • Patent number: 6546367
    Abstract: Statistical data including an average value, a standard deviation, and a minimum value of a phoneme duration of each phoneme is stored in a memory. When speech production time is determined for a phoneme string in a predetermined expiratory paragraph, the total phoneme duration of the phoneme string is set so as to become equal to the speech production time. Based on the set phoneme duration, phonemes are connected and a speech waveform is generated. To set a phoneme duration for each phoneme, a phoneme duration initial value is first set based on an average value, obtained by equally dividing the speech production time by phonemes of the phoneme string, and a phoneme duration range, phoneme. Then, set based on statistical data of each the phoneme duration initial value is adjusted based on the statistical data and the speech production time.
