摘要： An apparatus and method for preventing a computation error of band-by-band bit allocation between an encoder and a decoder. In the encoder, an input LSP (line spectrum pair) coefficient is quantized by a quantization device, and a quantized output is output. In a codebook referring section, the look up of a codebook in which computation results are prestored is performed by using an LSP index of the first stage, and band-by-band bit allocation information is created. LSP indexes for each quantization stage are supplied to a decoder. In the decoder, the look up of the codebook is performed using the LSP index, and dequantization is performed on the basis of the created band-by-band bit allocation information.

摘要： The processing volume in calculating a weight value for perceptually weighted vector quantization is decreased to speed up the processing or to minimize hardware. To this end, an inverted LPC finds LPC (linear prediction coding) residuals of an input speech signal which are processed with sinusoidal analysis encoding by a sinusoidal analysis encoding unit. The resulting parameters are processed by a vector quantizer with perceptually weighted vector quantization. For this perceptually weighted vector quantization, the weight value is calculated based on results of an orthogonal transform of parameters derived from the impulse response of the transfer function of the weight.

摘要： A method and apparatus for voiced/unvoiced decision for judging whether an input speech signal is voiced or unvoiced. The input parameters for performing the voiced/unvoiced (V/UV) decision are comprehensively judged in order to enable high-precision V/UV decision by a simplified algorithm. Parameters for the voiced/unvoiced (V/UV) decision include the frame-averaged energy of the input speech signal lev, the normalized autocorrelation peak value r0r, the spectral similarity degree pos, the number of zero crossings nZero, and the pitch lag pch. If these parameters are denoted by x, these parameters are converted by function calculation circuits using a sigmoid function g(x) represented byg(x)=A/(1+exp (-(x-b)/a))where A, a, and b are constants differing with each input parameter. Using the parameters converted by this sigmoid function g(x), the voiced/unvoiced decision is made a V/UV decision circuit.

摘要： Input audio signal is divided on a block-by-block basis. Frequency domain conversion is done on each of the blocks. Voiced bands of the frequency domain data for one of the blocks are searched for a voiced band B.sub.VH with the highest center frequency if it is decided that there are one or more shift points of voiced (V)/unvoiced (UV) decision data of all the bands. The number N.sub.V of voiced bands having center frequency less than that of the band B.sub.VH is found, so as to decide whether a proportion of the voiced bands is equal to or higher than a predetermined threshold N.sub.th, thereby deciding one V/UV boundary point. Thus, it is possible to replace the V/UV decision data for each band by information on one demarcation in all bands, thereby reducing data volume and bit rate.

摘要： Nasalized sound effects during reproduction of low-pitch sounds are suppressed to produce playback sounds of high clarity. Amplitude data is processed with high range formant emphasis of crests and valleys of the envelope of the frequency spectrum on the high frequency range and with deepening of the valley of the frequency spectrum over the entire frequency range, above all, over the low to mid frequency range. Next, the amplitude data is processed for emphasizing the peak values of the formant of the voiced frame in the portion of the speech signal which is rising in magnitude and for unconditionally emphasizing the spectral envelope on the high frequency range. The voiced speech spectrum is generated by synthesizing the cosine wave based upon the emphasized amplitude data.

摘要： A method and apparatus for reproducing speech signals at a controlled speed and for synthesizing speech includes a dividing unit that divides the input speech into time segments and an encoding unit that discriminates whether each of the speech segments is voiced or unvoiced. Based on the results of the discrimination, the encoding unit performs sinusoidal synthesis and encoding for voiced segments and vector quantization by closed-loop search for an optimum vector using an analysis-by-synthesis method for unvoiced segments in order to find encoded parameters. A period modification unit modifies the length of time associated with each signal segment and calculates a set of modified encoded parameters. In the speech synthesizing unit, encoded speech signal data is output from the encoding unit and pitch data and amplitude data specifying the spectral envelope are sent via a data conversion unit to a waveform synthesis unit, where the number of amplitude data points of the spectral envelope is changed without changing the shape of the spectral envelope, so that the pitch of the signal may be varied without changing its phoneme. A waveform synthesis unit synthesizes the speech waveform based on the converted spectral envelope data and pitch data.
