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.

Communication apparatus, control method for communication apparatus, and communication system

During wireless data communication with a digital camera, when a setting operation of communication parameters is designated by a communication setting button, the data communication with the camera is suspended, and the network is switched to a network for setting communication parameters for another camera. With this network, a setting operation of communication parameters for another camera is performed. Thereafter, the network for setting communication parameters is switched to the network for data communication with the original camera.

Image-taking control apparatus and notification method

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 (p) 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.

Speech synthesizing method and apparatus

A wireless communication apparatus stores a plurality of cellular phones in an extension, connects a plurality of cellular phones to a base station, and sets up the communication speed of a communication channel to a base station according to the communication speeds of a plurality of the cellular phones. The wireless communication apparatus maintains the communication speed of a communication channel when a total sum of the speed of the communication which one of the plurality of cellular phones starts and the speed of the communication previously performed is equal to or less than the communication speed of the communication channel. An IMT2000 network stores the wireless communication apparatus and the base station corresponding to a plurality of cellular phones in a location registration database and processes incoming calls to a plurality of cellular phones according to the location registration database. Further, the IMT2000 network performs a location registration to a public network corresponding to a plurality of cellular phones (PHS, PDC).

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.

A speech synthesis apparatus for outputting synthesized speech on the basis of a parameter sequence of a speech waveform includes a parameter generation unit which generates a parameter sequence for speech synthesis on the basis of a character sequence input by a character sequence input unit, and stores the generated parameter sequence in a parameter storage unit. A waveform generation unit is also provided that generates pitch waveforms each for one pitch period on the basis of synthesis parameters and pitch scales included in the parameter sequence, and generates a speech waveform by connecting the generated pitch waveforms in accordance with frame lengths set by a frame length setting unit.

Speech synthesis apparatus and method

A document inputting apparatus or speech outputting apparatus inputs and displays document data, specifies accent information, pronunciation information and syllable-length information of words or characters of the document data. The apparatus displays the document data in accordance with the specified information so that information such as the accent positions or accent intensities can be recognized. Thus formed document data is stored in a memory with the accent information, the pronunciation information or the syllable-length information. Upon reading the document data from the memory and outputting it as speech, the specified information is referred to for speech synthesizing, thus outputting speech corresponding to the correct pronunciation.

A data processing apparatus for synchronized audiovisual output has synchronizing signal bits which are assigned to bits of each sound data, represented by a 16-bit PCM code. A predetermined bit of the assigned bits having the least influence upon the human auditory sense is extracted as a synchronizing signal bit for synchronization of the image data output and sound output.

A speech synthesis method and a speech synthesis apparatus includes a system for synthesis by rule that prevents the quality of synthesized speech from deteriorating and for reducing the number of calculations that are required for the generation of a speech waveform. The speech synthesis apparatus includes a character series input section, for inputting a character series as phonetic text, a pitch waveform generator, for generating a pitch waveform by calculating a product of a matrix, which has been acquired for each pitch, and the character series, which is input by the character series input section, and a device for connecting pitch waveforms that are generated by the pitch waveform generator and for providing a speech waveform.
