摘要： An input speech signal to an input terminal is supplied to a speech synthesizer section through a speech analyzer section and frequency parameter quantizer section to form a synthesis filter, and the input speech signal is expressed by quantized LPC coefficients representing the characteristics of the synthesis filter and an excitation signal for exciting the synthesis filter. In this case, in a pulse excitation section, a pulse position selector selects pulse position candidates from the integer pulse positions and non-integer pulse positions stored in a pulse position codebook, and an integer position pulse generator and non-integer position pulse generator respectively generate integer position pulses set at sampling points of the excitation signal and non-integer position pulses set at positions located between sampling points. These pulses are synthesized into a pulse train serving as a source of an excitation signal.

摘要： The apparatus of the present invention includes an inverted J-shaped pipe disposed under the sea and including shorter and longer open end portions, and a connecting portion joining them such that the shorter and longer portions extend downward from connecting portion to their respective open ends. An injector nut injecting the carbon dioxide-containing gas into a portion of said short pipe adjacent to said first open end into said shorter pipe. An accumulator is in fluid communication with the connecting portion for collecting gas, which remains undissolved in the seawater during the passage of the carbon dioxide-containing gas through said shorter pipe. According to the method of the invention, the injection of the carbon dioxide-containing gas forces the seawater to enter into first open end, to flow upward together with the carbon dioxide-containing gas through the shorter pipe portion, to flow downward through the longer pipe portion and to be discharged from the second open end, with the carbon dioxide being dissolved in the seawater during the passage of the carbon dioxide-containing gas through the shorter pipe portion, so that the seawater discharged from the second open end contains carbon dioxide dissolved therein.

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 speech synthesis apparatus synthesize a speech signal by filtering a speech source signal through a synthesis filter. A speech source signal codebook stores a plurality of speech source signals as a code vector. A unit dictionary memory stores a plurality of synthesis units corresponding to phonemic symbols, each synthesis unit comprising an index of the code vector in the speech source codebook and a shift number for the code vector to decode the speech source signal. A unit selection section selects a synthesis unit corresponding to phonemic symbols to be synthesized from the unit dictionary memory. A synthesis unit decoder selects the code vector corresponding to the index in the synthesis unit from the speech source signal codebook, and shifts the code vector according to the shift number in the synthesis unit.

摘要： On the basis of an autocorrelation coefficient calculated by an autocorrelation coefficient computation section from an input speech signal, an LSF computation section computes LSF parameters F(k) (k=1, 2, . . . , N). A modified logarithmic transformation section performs on the LSF parameters a logarithmic transformation with offset defined by f(k)=logC (1+A.times.F(k)) to obtain modified logarithmic LSF parameters f(k). The resulting modified logarithmic LSF parameters are quantized by a quantization section to provide quantized LSF parameters fq(k). Codes representing the quantized LSF parameters fq(k) are outputted. An inverse transformation defined by Fq(k)=(C.sup.fq(k) -1)/A is performed on the LSF parameters fq(k) to output LSF parameters Fq(k) on the general frequency scale.
