<p><P>PROBLEM TO BE SOLVED: To provide a voice data processing apparatus capable of processing to prevent noise from occurring with small power consumption. <P>SOLUTION: In the voice data processing apparatus, an internal clock transmits continuous voice data included in a digital signal input in synchronism with a first clock to a voice output device of a second clock. The voice data processing apparatus comprises: a first memory for storing the voice data; a second memory for storing the voice data preceding the first memory; a phase comparing part for comparing phases of the first and second clocks to output a phase difference detection signal; a separator part for separating the voice data and the first clock from the digital signal to output the voice data to the first memory; and a control part for storing the voice data of the first memory in the second memory after transmitting the voice data of the first memory when synchronism is determined or the voice data of the second memory when asynchronism is determined in synchronism with the second clock, respectively, based on the phase difference detection signal. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
