<p>PROBLEM TO BE SOLVED: To provide a voice transmission system in which instantaneous interruption of communication does not occur even if a low-order device is added or deleted.SOLUTION: Voice processing devices 1 and 2 include: word clock generation parts 11 and 21; voice processing parts 10 and 20 each for applying voice processing to a voice signal with a generated word clock as a reference; delay time setting parts 12 and 22 each for acquiring a transmission delay time between the voice processing device and a low-order device connected thereto and a preset fixed delay time; stage setting parts 14 and 24 each for setting the number of stages for cascade connection to a most significant device; transmitting parts 16 and 26 and receiving parts 17 and 27 for transmitting/receiving frame data between the voice processing devices. A low-order device 2 defines reception timing of frame data from the high-order device 1 as a reference and generates a word clock of the device per se in timing that is obtained by subtracting the transmission delay time from a frame format term, thereby synchronizing word clocks between the high-order device 1 and the low-order device 2.</p> |
