| Summary, etc | Successful categorization of phonemes in speech requires that the brain analyze the acoustic signal along<br/>both spectral and temporal dimensions. Neural encoding of the stimulus amplitude envelope is critical<br/>for parsing the speech stream into syllabic units. Encoding of voice onset time (VOT) and place of<br/>articulation (POA), cues necessary for determining phonemic identity, occurs within shorter time frames.<br/>An unresolved question is whether the neural representation of speech is based on processing mechanisms<br/>that are unique to humans and shaped by learning and experience, or is based on rules governing<br/>general auditory processing that are also present in non-human animals. This question was examined by<br/>comparing the neural activity elicited by speech and other complex vocalizations in primary auditory<br/>cortex of macaques, who are limited vocal learners, with that in Heschl’s gyrus, the putative location of<br/>primary auditory cortex in humans. Entrainment to the amplitude envelope is neither specific to humans<br/>nor to human speech. VOT is represented by responses time-locked to consonant release and voicing<br/>onset in both humans and monkeys. Temporal representation of VOT is observed both for isolated syllables<br/>and for syllables embedded in the more naturalistic context of running speech. The fundamental<br/>frequency of male speakers is represented by more rapid neural activity phase-locked to the glottal<br/>pulsation rate in both humans and monkeys. In both species, the differential representation of stop<br/>consonants varying in their POA can be predicted by the relationship between the frequency selectivity<br/>of neurons and the onset spectra of the speech sounds. These findings indicate that the neurophysiology<br/>of primary auditory cortex is similar in monkeys and humans despite their vastly different experience<br/>with human speech, and that Heschl’s gyrus is engaged in general auditory, and not language-specific,<br/>processing.<br/> |
