| Abstract: | In telephone speech signal,it is different that different frequency copanents effect on the naturalness and knowability of speech signal.The resrtaint bandwidth anslysis is for analysing the action of different frequency in speech signal.It is a precondition to ensure speech knowability,it makes some foundation for compress signal bandwidth,in order to find out a secure,economical and practical method for telephone encipherment |
