Abstract

A method and apparatus for speech transmission including inband signalling, comprising a sampler (3) for digitally sampling the speech signal to product block of bits representing the speech signal, means (15) for providing a queue of inband signals to be transmitted with the speech signal, a detector (13) for monitoring the speech signal for periods of speech with low likelihood of degradation due to the insertion of the inband signals, and an insertion device (9) for inserting inband signals form the queue (15) into the blocks of bits representing the speech signal during the periods of speech with low likelihood of degradation. As a result, inband signals can be transmitted with a speech signal without degrading the apparent quality of the speech signal for a user of the system.
