    摘要: 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.

    摘要: 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. The calculation method for the generation of such a pitch waveform provides a great reduction in the number of calculations that are required. In addition, in the calculation for the generation of a pitch waveform, a function that determines a frequency response is employed to convert a spectral envelope, which is obtained from a parameter, so that the timbres of synthesized speech can be changed without parameter operations.

    摘要: In a speech synthesizer, each frame for generating a speech waveform has an expansion degree to which the frame is expanded or compressed in accordance with the production speed of synthetic speech. In accordance with the set speech production speed, the time interval between beat synchronization points is determined on the basis of the speed of the speech to be produced, and the time length of each frame present between the beat synchronization points is determined on the basis of the expansion degree of the frame. Parameters for producing a speech waveform in each frame are properly generated by the time length determined for the frame. In the speech synthesizer for outputting a speech signal by coupling phonemes constituted by one or a plurality of frames having phoneme vowel-consonant combination parameters (VcV, cV, or V) of the speech waveform, the number of frames can be held constant regardless of a change in the speech production speed. This prevents degradation in the tone quality or a variation in the processing quantity resulting from a change in the speech production speed.

    摘要: An apparatus and method for processing vocal information includes an extractor for extracting a plurality of spectrum information from parameters for vocal information, a vector quantizer for vector-quantizing the extracted spectrum information and for producing a plurality of parameter patterns therefrom, a memory for storing the plurality of parameter patterns so obtained, and a memory for storing positional information indicating the positions at which the plurality of parameter patterns are stored and for storing code information specifying parameter patterns and corresponding to the positional information. The parameter patterns and code information can be used to synthesize speech. Because a small number of parameter patterns are used, only a small memory capacity is needed and efficient processing of vocal information can be performed.
