Abstract: Presented herein are systems and methods for generating an adaptive noise codebook for use with electronic speech systems. The noise codebook includes a plurality of entries which may be updated based on environmental noise sounds. The speech system includes a speech codebook and the adaptive noise codebook. The system identifies speech sounds in an audio signal using the speech and noise codebooks.

Abstract: In this embedded signalling system a sequence of code symbols representing digital information is generated (100). A code signal representing this sequence is generated (200), which is dynamically filtered to form a modified code signal (300), which is combined (400) with a higher level audio signal to form a composite audio signal for transmission.
