Sparse codes for speech predict spectrotemporal receptive fields in the inferior colliculus.

We have developed a sparse mathematical representation of speech that minimizes the number of active model neurons needed to represent typical speech sounds. The model learns several well-known acoustic features of speech such as harmonic stacks, formants, onsets and terminations, but we also find m...
