PURPOSE:To stably obtain the synthetic voice of a high quality by constituting a means for converting a voice spectrum to an impulse response waveform, so as to operate a low-pass component of the voice spectrum. CONSTITUTION:A buffer memory 103 constituted of two faces is provided in order to adjust the time of a processing and to prevent an interruption of an input voice. Also, the device is provided with a frame data segmenting part 104, a DC component adjusting part 106, and a power spectrum envelope (PSE) analyzing part 108. Moreover, this device is provided with a spectrum envelope reproducing part 111, and impulse response converting part 113, a DC component correcting part 115, a superposing part 117, a buffer memory 118 of two faces for an output, and a digital-analog (D/A) converter 119. In such a state, a low- pass component of voice spectrum is operated by the inpulse response converting part 113 of the voice spectrum. In such a way, a synthetic voice of a high quality can stably be obtd. |
