ABSTRACT:
An audio signal transmission apparatus for use in a system for judging whether voice or sound is present or not to transmit only the voice presence portion of a digital audio signal which apparatus transmits data inputted earlier than the judgment time of the voice presence to thereby prevent the head of a word from being lost and dissolves the delay time caused at this time by compressing the time axis. The apparatus includes a delay circuit for storing a past audio signal data train, a time axis compression unit for compressing an audio signal taken out from the delay circuit through a switch and an audio signal inputted through a switch on a time axis, a level judgment unit for judging whether the audio signal is present or not to operate the switches, and a data conversion unit for converting the digital audio signal into parameters to be transmitted. An audio signal data train inputted earlier than the judgment time of the voice presence can be transmitted without occurrence of a delay time to thereby prevent the head of a word starting from a frictional or explosive consonant sound from being lost.
