    摘要: Respective samples of input speech data are transformed by a discrete Fourier transformer to obtain a spectrum of the speech data. Simultaneously, values of times of the respective samples are multiplied with the input speech data by a multiplier and a differential spectrum is obtained by transforming a result of the multiplication by a discrete Fourier transformer. A real part of a value obtained by dividing the differential spectrum by the spectrum by a quotient real part calculator and the real part is inverse-transformed by a discrete inverse Fourier transformer. The result of the inverse-transformation is divided by the values of the times of the respective samples to obtain a time function corresponding to phase. On the other hand, a time function corresponding to a logarithmic amplitude spectrum is obtained from an output of the inverse-Fourier transformer by means of a logarithmic amplitude spectrum calculator. A complex cepstrum is obtained by adding the both time functions at respective times by an adder.

    摘要: A logarithmic frequency spectrum related to an input signal is converted by the use of an inverse Fourier transform into a cepstrum. The cepstrum has a first and a second frequency component which have a first peak and a second peak spaced apart from the first peak by a preselected period on an axis of frequency, respectively. The second frequency component is processed into a peak controlled frequency component having a controlled peak coincident with the first peak. The peak controlled frequency component and the first frequency component are summed up to produce an ultimate frequency component which corresponds to the value of the envelope parameter.

    摘要: A text-to-speech synthesizer comprises an analyzer that decomposes a sequence of input characters into phoneme components and classifies them as a first group of phoneme components or a second group if they are to be synthesized by a speech parameter or by a formant rule, respectively. Speech parameters derived from natural human speech are stored in first memory locations corresponding to the phoneme components of the first group and the stored speech parameters are recalled from the first memory in response to each of the phoneme components of the first group. Formant rules capable of generating formant transition patterns are stored in second memory locations corresponding to the phoneme components of the second group, the formant rules being recalled from the second memory in response to each of the phoneme components of the second group. Formant transition patterns are derived from the formant rule recalled from the second memory, and formants of the derived transition patterns are converted into corresponding speech parameters. Spoken words are digitally synthesized from the speech parameters recalled from the first memory as well as from those supplied from the converted speech parameters.

    摘要: In order to simplify a speech synthesizer arrangement concurrently with improvement of operation flexibility thereof, a digital memory is arranged to store at least one voiced sound source and at least one unvoiced sound source. One of the sound sources is selected in accordance with the content of a first register, while the data within the selected source is specified by the content of a shift register sequence generator. Each of the bit patterns obtained at the shift register sequence generator is compared with the content of a second register. In the event that the contents of the sequence generator and the second register coincide, the shift register sequence generator is reset and/or the operating conditions(s) of the synthesizer is changed.

    摘要: Input data are analyzed by FFT, etc. in an analyzing section and power every frequency band is calculated and sent to a control section. In a gain control section, changing characteristics of a gain used in the control section are calculated on the basis of hearing ability characteristics of a user obtained from a memory section and a gain setting memory section, a sound pressure for starting a reduction in gain, and a sound pressure for setting the gain to be equal to or greater than 0 dB. The calculated changing characteristics are sent to the control section. In the control section, the gain every frequency band required in a hearing sense compensating section is determined on the basis of analyzed results obtained from the analyzing section, the hearing ability characteristics of the user obtained from the memory section, and the changing characteristics of the gain obtained from the gain control section. The control section sends data of the gain to the hearing sense compensating section. The hearing sense compensating section obtaining the input data and the gain data performs hearing sense compensation processing with respect to the input data and sends the processed input data to an output section.
