“…Distinctive phonological features such as [6back] are traditionally defined in terms of their articulatory consequences (Halle, 1992). The phonetic cues that give rise to their perception have also been described in terms of articulatory categories (Liberman and Mattingly, 1985) or in terms of specific combinations of acoustic signal properties (Jacobson, Fant, and Halle, 1952; for reviews of the field, see Raphael, 2005;Stevens, 2005;Clements and Hallé, 2010).…”

The mental organization of linguistic knowledge and its involvement in speech processing can be investigated using the mismatch negativity (MMN) component of the auditory event-related potential. A contradiction arises, however, between the technical need for strict control of acoustic stimulus properties and the quest for naturalness and acoustic variability of the stimuli. Here, two methods of preparing speech stimulus material were compared. Focussing on the automatic processing of a phonotactic restriction in German, two corresponding sets of various vowel-fricative syllables were used as stimuli. The former syllables were naturally spoken while the latter ones were created by means of cross-splicing. Phonetically, natural and spliced syllables differed with respect to the appropriateness of coarticulatory information about the forthcoming fricative within the vowels. Spliced syllables containing clearly misleading phonetic information were found to elicit larger N2 responses compared to their natural counterparts. Furthermore, MMN results found for the natural syllables could not be replicated with these spliced stimuli. These findings indicate that the automatic processing of the stimuli was considerably affected by the stimulus preparation method. Thus, in spite of its unquestioned benefits for MMN experiments, the splicing technique may lead to interference effects on the linguistic factors under investigation.

“…This confound is not easily avoided. Most of the acoustic properties associated with phonetic categorization are in fact relatively brief (on the order of tens to hundreds of milliseconds), and typically involve rapid spectral changes (Raphael, 2005). In contrast, those associated with talker identity typically involve much longer-term variability, and often unfold completely only over the course of much longer utterances (Kreiman, Van Lancker-Sidtis, & Gerratt, 2005).…”

Training to use voice onset time as a cue to talker identification induces a left-ear/right-hemisphere processing advantage

We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n=8) showed faster response times for stimuli presented only to the left ear than for those presented only to the right. The development of a leftear/right-hemisphere advantage for processing a prototypically phonetic cue supports a model of speech perception in which lateralization is driven by functional demands (talker identification vs. phonetic categorization) rather than by acoustic stimulus properties alone.

“…If simple source features mapped in a relatively straightforward manner to sound, the basis for listener perception of the speech features would have been easy to identify. One hallmark of more than half a century of speech research, however, has been the failure to identify invariant acoustic cues for features of production (see, e.g., Raphael, 2005). Rejecting the possibility of a complex mapping between source and sound, speech perception is often assumed to involve some form of a highly specialized, closed module (e.g., Liberman & Mattingly, 1985), possibly one initially shaped by early experience (e.g., Werker & Tees, 1999).…”

There is a small but growing literature on the perception of natural acoustic events, but few attempts have been made to investigate complex sounds not systematically controlled within a laboratory setting. The present study investigates listeners' ability to make judgments about the posture (upright-stooped) of the walker who generated acoustic stimuli contrasted on each trial. We use a comprehensive three-stage approach to event perception, in which we develop a solid understanding of the source event and its sound properties, as well as the relationships between these two event stages. Developing this understanding helps both to identify the limitations of common statistical procedures and to develop effective new procedures for investigating not only the two information stages above, but also the decision strategies employed by listeners in making source judgments from sound. The result is a comprehensive, ultimately logical, but not necessarily expected picture of both the source-sound-perception loop and the utility of alternative research tools.
