Compression of speech may be achieved through the adaptive generation of a compressed sound output. A first processing element may be used to characterize a first sound representation such that a first characterization result is produced. A comparison element may be provided to compare a first comparison input that is related to the first sound representation with a second comparison input that is related to the first characterization result. A determination may be made on whether further processing is desirable based on whether the first comparison result satisfies a first predetermined threshold criteria. Additionally, a second processing element may be included to characterize a second sound representation and to produce a second characterization result only if the first comparison result satisfies the first predetermined threshold. A compressed sound output is generated whose contents are determined based on at least the first comparison result.
