“…However, on a practical level it can be very difficult to separate the actions of these two hypothetical observer strategies in actual experiments ͑however, cf. de Cheveigné et al, 1995͒. This is partly because, in masked conditions, both produce similar effects and both may result in selective/tuned responses along a given perceptual dimension.…”

“…In addition, given that simple tonal stimuli stream more readily at faster rates ͑van Noorden, 1975͒, two different rates of presentation are examined. Furthermore, the current work examines the effects of linking together target versus masker words and the implications of that comparison for the ability to selectively attend to one source or actively ignore a second source ͑see also de Cheveigné et al, 1995 andSimpson, 2007͒.…”

In a variation on a procedure originally developed by Broadbent ͓͑1952͒. "Failures of attention in selective listening," J. Exp. Psychol. 44, 428-433͔ listeners were presented with two sentences spoken in a sequential, interleaved-word format. Sentence one ͑target͒ comprised the odd-numbered words in the sequence and sentence two ͑masker͒ comprised the even-numbered words in the sequence. The task was to report the words in sentence one. The goal was to determine the effectiveness of cues linking the words of the target ͑or masker͒ over time. Three such "linkage variables" were examined: ͑1͒ fixed talker, ͑2͒ fixed perceived interaural location, and ͑3͒ correct syntactic structure. All of the linkage variables provided a significant advantage when applied to the target compared to the baseline condition in which the linkage variables were randomized. However, these linkage variables were not effective when applied to the masker. Word position effects were found such that performance in the baseline condition declined, and the advantages of the linkage variables increased, for the words near the end of the sentence. Overall, this approach appears to be useful for examining interference in speech recognition that has little or no peripheral component. The results suggest that variables that link target words together improve their resiliency to interference and/or their recall.

“…Here, using a large number of observations, we found no such interaction. Thus, it truly seems that pitch estimation does not help recognition based on timbre, at least for short durations and when there is no competing sound (de Cheveign e et al, 1995).…”

Sounds such as the voice or musical instruments can be recognized on the basis of timbre alone. Here, sound recognition was investigated with severely reduced timbre cues. Short snippets of naturally recorded sounds were extracted from a large corpus. Listeners were asked to report a target category (e.g., sung voices) among other sounds (e.g., musical instruments). All sound categories covered the same pitch range, so the task had to be solved on timbre cues alone. The minimum duration for which performance was above chance was found to be short, on the order of a few milliseconds, with the best performance for voice targets. Performance was independent of pitch and was maintained when stimuli contained less than a full waveform cycle. Recognition was not generally better when the sound snippets were time-aligned with the sound onset compared to when they were extracted with a random starting time. Finally, performance did not depend on feedback or training, suggesting that the cues used by listeners in the artificial gating task were similar to those relevant for longer, more familiar sounds. The results show that timbre cues for sound recognition are available at a variety of time scales, including very short ones.

“…Harmonics of the same f 0 tend to fuse together to form a single percept with a pitch of f 0 . The perceptual fusion of harmonics can be used for segregating different sound sources (1)(2)(3) or to facilitate the discrimination of vocal communication sounds in noisy environments (4)(5)(6). Harmonicity is also an important principle in the context of music perception.…”

Harmonic template neurons in primate auditory cortex underlying complex sound processing

Harmonicity is a fundamental element of music, speech, and animal vocalizations. How the auditory system extracts harmonic structures embedded in complex sounds and uses them to form a coherent unitary entity is not fully understood. Despite the prevalence of sounds rich in harmonic structures in our everyday hearing environment, it has remained largely unknown what neural mechanisms are used by the primate auditory cortex to extract these biologically important acoustic structures. In this study, we discovered a unique class of harmonic template neurons in the core region of auditory cortex of a highly vocal New World primate, the common marmoset (Callithrix jacchus), across the entire hearing frequency range. Marmosets have a rich vocal repertoire and a similar hearing range to that of humans. Responses of these neurons show nonlinear facilitation to harmonic complex sounds over inharmonic sounds, selectivity for particular harmonic structures beyond two-tone combinations, and sensitivity to harmonic number and spectral regularity. Our findings suggest that the harmonic template neurons in auditory cortex may play an important role in processing sounds with harmonic structures, such as animal vocalizations, human speech, and music. marmoset | auditory cortex | music | harmonic | hearing
