摘要： An information extraction unit extracts spectral envelope information of L-dimension from each frame of speech data by discrete Fourier transform. The spectral envelope information is represented by L points. A basis storage unit stores N bases (L>N>1). Each basis is differently a frequency band having a maximum as a peak frequency in a spectral domain having L-dimension. A value corresponding to a frequency outside the frequency band along a frequency axis of the spectral domain is zero. Two frequency bands of which two peak frequencies are adjacent along the frequency axis partially overlap. A parameter calculation unit minimizes a distortion between the spectral envelope information and a linear combination of each basis with a coefficient for each of L points of the spectral envelope information by changing the coefficient, and sets the coefficient of each basis from which the distortion is minimized to a spectral envelope parameter of the spectral envelope information.

摘要： A phoneme sequence corresponding to a target speech is divided into a plurality of segments. A plurality of speech units for each segment is selected from a speech unit memory that stores speech units having at least one frame. The plurality of speech units has a prosodic feature accordant or similar to the target speech. A formant parameter having at least one formant frequency is generated for each frame of the plurality of speech units. A fused formant parameter of each frame is generated from formant parameters of each frame of the plurality of speech units. A fused speech unit of each segment is generated from the fused formant parameter of each frame. A synthesized speech is generated by concatenating the fused speech unit of each segment.

摘要： According to one embodiment, a first storage unit stores n band noise signals obtained by applying n band-pass filters to a noise signal. A second storage unit stores n band pulse signals. A parameter input unit inputs a fundamental frequency, n band noise intensities, and a spectrum parameter. A extraction unit extracts for each pitch mark the n band noise signals while shifting. An amplitude control unit changes amplitudes of the extracted band noise signals and band pulse signals in accordance with the band noise intensities. A generation unit generates a mixed sound source signal by adding the n band noise signals and the n band pulse signals. A generation unit generates the mixed sound source signal generated based on the pitch mark. A vocal tract filter unit generates a speech waveform by applying a vocal tract filter using the spectrum parameter to the generated mixed sound source signal.
