    摘要: A pitch period extracting apparatus includes a microcomputer which determines a sampling frequency for an A/D converter, and a range of delay times for calculating autocorrelative values on the basis of the sampling frequency. For example, the delay times are set within a range of 20 samples.ltoreq.k.ltoreq.100 samples in a case of 8 kHz, and a range of 15 samples.ltoreq.k.ltoreq.75 samples in a case of 6 kHz. The microcomputer calculates the autocorrelative values of speech signal data stored in a buffer memory, and outputs a delay time at which a maximum autocorrelative value is obtainable as a pitch period of an inputted speech signal.

    摘要: An echo prevention circuit comprises an input terminal to which a first input signal is input; a first FIR filter into which the first input signal is input through the input terminal; a second FIR filter into which the first input signal is input at the same time as into the first FIR filter; an input/output terminal to which an output signal of the first FIR filter is output or a second input signal is input; a subtracter that subtracts an output signal of the second FIR filter from a combined signal of the output signal of the first FIR filter and the second input signal; and an output terminal to which an output signal of the subtracter is output. The first and the second FIR filters have such filter coefficients that the output signal through the output terminal has only the output signal from the first FIR filter removed.

    摘要: A encoded-sound-code decoding method comprises a first step of performing a decoding process on a predetermined number of sample codes starting from a sound-reproduction start position at some midpoint of a sequence of codes based on a predetermined initial value of a sound parameter; a second step of making comparison between a judgment parameter corresponding to a decoding result and a predetermined threshold value thereby determining whether the decoding result is proper or not; a third step in which, in response to a determination that the decoding result is not proper, the initial value of the sound parameter used at the first step is modified and then the processes of the first and second steps are performed; and a fourth step in which, after repetitions of the process of the third step until the decoding result is determined to be proper, the codes are sequentially decoded from the sound-reproduction start position at some midpoint of the code sequence.

    摘要: The present invention relates to a data write control method for writing at least two types of data to memory. A multi-valued memory to which information composed of two values can be written per cell and information composed of three or more values can be also written per cell is used as the memory. When at least two types of data are written to the multi-valued memory, the amount of information to be written per cell in the multi-valued memory is controlled depending on the type of the data.
