摘要： A method and apparatus for encoding an input signal, such as a broad-range speech signal, in which a number of decoding operations with different bit rates are enabled for assuring a high encoding bit rate and for minimizing deterioration of the reproduced sound even with a low bit rate. The signal encoding method includes a band-splitting step for splitting an input signal into a number of bands and a step of encoding signals of the bands in a different manner depending on signal characteristics of the bands. Specifically, a low-range side signal is taken out by a low-pass filter from an input signal entering a terminal, and analyzed for Linear Predictive coding by an Linear Predictive coding analysis quantization unit. After finding the Linear Predictive coding residuals, as short-term prediction residuals by an Linear Predictive coding inverted filter, the pitch is found by a pitch analysis circuit. Then, pitch residuals are found by long-term prediction by a pitch inverted filter. The pitch residuals are processed with modified discrete cosine transform by a modified discrete cosine transform (MDCT) circuit and vector-quantized by a vector-quantization circuit. The resulting quantization indices are transmitted along with the pitch lag and the pitch gain. The linear spectral pairs linear spectral pairs are also sent as parameter representing LPC coefficients.

摘要： In a sound synthesizer, a noise adder generates a noise signal having a frequency band of 3,400 to 4,600 Hz, adjusts the gain of the noise signal, and adds the gain-adjusted noise signal to an excitation source after being filled with zeros by a zero-filling circuit, thereby providing a wide-band excitation source which is rather flat. The signal gain is adjusted by determining a narrow-band excitation source or a power of the wide-band excitation source after being filled with zeros and fitting the gain to the narrow-band excitation source or the power.

摘要： A signal decoding method and apparatus in which the speech signal reproducing speed is controlled without changing the phoneme or the pitch, in which the apparatus has a data number convertor for converting the number of orthogonal transform coefficients entering a transmission signal input terminal from N to M, an inverse orthogonal transform unit for inverse orthogonal-transforming the M number of the orthogonal transform coefficients obtained by the data number convertor, and a linear predictive coding synthesis filter for performing predictive synthesis based on the short-term prediction residuals obtained by the inverse orthogonal transform unit. For an input signal, short-term prediction residuals are found and are orthogonally transformed to form the orthogonal transform coefficients at a rate of N coefficients per transform unit. The frequency positions of the N transform coefficients may be rearranged to M values by M/N or by oversampling to change N to M. A portable radio terminal embodying the invention is described.

A message from the animation character AC is voice synthesized in a voice synthesizing circuit 19 and the synthesized voice is outputted from a speaker 20.The electronic equipment can be operated as if the user were talking with the animation character, so that a natural man-machine interface can be realized.
