TLDR
It is concluded that categorical perception of sounds is not unique to speech and suggested that it may be a general property of sensory behavior.Abstract:
The onset of a noise [0.9–2.1 kHz, 55 dB SPL (A weighted)] preceded that of a buzz [100 Hz, 0.5–3.0 kHz, 70 db SPL (A weighted), 500 msec] by −10 to +80 msec and both terminated simultaneously. Eight adults discriminated among noise‐lead times in an oddity task. In separate sessions, they labeled singly presented stimuli with either of the two responses: ’’no noise’’ or ’’noise.’’ The results are highly similar to those reported for the categorical perception of synthetic plosive consonants differing in voice‐onset time. On the average, discrimination was best across a noise‐lead‐time boundary of about 16 msec, where labeling also shifted abruptly. These results and those of categorical perception, generally, are interpreted in terms of Weber’s law as applied to a single component within a stimulus complex. It is concluded that categorical perception of sounds is not unique to speech and suggested that it may be a general property of sensory behavior.Subject Classification: [43]65.75; [43]70.30.read more

Neural Substrates of Phonemic Perception
TL;DR: It is shown that an area extending along the left middle and anterior superior temporal sulcus (STS) is more responsive to familiar consonant-vowel syllables during an auditory discrimination task than to comparably complex auditory patterns that cannot be associated with learned phonemic categories.

Phonetic and phonological representation of stop consonant voicing
TL;DR: In this paper, the authors argue for a more structured view of the relation between the phonological feature [voice] and its specific phonetic implementations, and discuss how surface phonetic variation, within and across languages, can be derived in a synchronic grammar from the interaction of three relatively simple systems: the possible phonological features and their values, their possible phonetic category mappings, and phonetic detail rules accounting for variation within these phonetic categories.
