    • There are provided a high frequency signal interpolation method and a high frequency signal interpolation device for forming a preferable high frequency signal with a simple configuration and favorably performing practical high frequency signal interpolation.Therefore, according to the present invention, a compressed digital audio signal reproduced from a digital audio device is supplied as a raw signal to an input terminal 1. The raw signal is supplied, for example, to a Hilbert conversion circuit 2 for generating an analytic signal. A real part R and an imaginary part I of the analytic signal are taken out, independently. Furthermore, the real part R and the imaginary part I are supplied to square circuits 3 and 4, respectively. Subsequently, squared signals are added in an adder circuit 5, respectively. The added signal is supplied to a square-root circuit 6 and an envelope component of the raw signal is taken out. A harmonic component is formed in the envelop component. Thus, a high-harmonic portion of the envelope component taken out at the square-root circuit 6 is taken out by a high-pass filter (HPF) 7. On the other hand, a signal from which a high frequency portion of the raw signal from the input terminal 1 is removed by a low-pass filter 8 is formed. These signals are added by an adder circuit 9 and then output to an output terminal 10. Accordingly, the interpolation is carried out by forming the envelope component of the raw signal using the real part and the imaginary part of the analytic signal of the raw signal; and taking the high-harmonic portion out of the formed envelope component. Therefore, a favorable high frequency signal is formed by an extremely simplified configuration and practical high frequency signal interpolation can be carried out.

    • A voice signal interpolation apparatus is provided which can restore original human voices from human voices in a compressed state while maintaining a high sound quality. When a voice signal representative of a voice to be interpolated is acquired by a voice data input unit 1, a pitch deriving unit 2 filters this voice signal to identify a pitch length from the filtering result. A pitch length fixing unit 3 makes the voice signal have a constant time length of a section corresponding to a unit pitch, and generates pitch waveform data. A sub-band dividing unit 4 converts the pitch waveform data into sub-band data representative of a spectrum. A plurality of sub-band data pieces are averaged by an averaging unit 5 and thereafter a sub-band synthesizing unit 6 converts the sub-band data pieces into a signal representative of a waveform of the voice by a sub-band synthesizing unit 6. The time length of this signal in each section is restored by a pitch restoring unit 7 and a sound output unit 8 reproduces the sound represented by the signal.

    • The present invention provides a voice data selector and the like for obtaining natural synthetic speech at high speed in simple configuration. In a voice data selector of the present invention, when data expressing a message template is supplied, a voice unit editor retrieves voice unit data of a voice unit, whose reading agrees with a voice unit in the message template, from a voice unit database. On the other hand, the voice unit editor performs the cadence prediction of a message template, and specifies what agrees with each voice unit in a message template most suitably from among the retrieved voice unit data on the basis of an evaluation expression. The evaluation expression has variables of cadence prediction result, that is, the result of the primary regression of a frequency of a pitch component between voice unit data, and the time difference of utterance speed. Then, the specified voice unit data and waveform data, which an acoustic processor is made to supply instead because of unsuccessful specification, are combined with each other, and data expressing synthetic speech is generated.
