Speech Signals Might Ignore Auditory Processors

Identification ratings were taken from English monolingual subjects on a noise-lead-time (NLT) continuum. An improved signal detection model was employed for fitting the results. Previous experiments showed that the model could fit a TOT (tone-onset-time) but not a VOT (voice-onset-time) continuum. It could be argued that this difference arises from the different acoustic complexity of the two continua. In order to show that acoustic complexity cannot account for these results, a more complex nonspeech continuum was used in this experiment. It is shown that the model cannot fit the NLT continuum either. The results are discussed in terms of the possible modularity of speech processes.
