Investigating the neural code for dynamic speech and the effect of signal degradation
Steadman, Mark (2015) Investigating the neural code for dynamic speech and the effect of signal degradation. PhD thesis, University of Nottingham.
It is common practice in psychophysical studies to investigate speech processing by manipulating or reducing spectral and temporal information in the input signal. Such investigations, along with the often surprising performance of modern cochlear implants, have highlighted the robustness of the auditory system to severe degradations and suggest that the ability to discriminate speech sounds is fundamentally limited by the complexity of the input signal. It is not clear, however, how and to what extent this is underpinned by neural processing mechanisms.
