Abstract Voice or speaker recognition is critical in a wide variety of social contexts. In this study, we investigated the contributions acoustic, phonological, lexical and semantic information toward voice recognition. Native English speaking participants were trained to recognize five speakers conditions: non-speech, Mandarin, German, pseudo-English English. We showed that significantly improved as more became available, from purely acoustic features non-speech additional phonological...
Significance The “cocktail party problem” is encountered when sounds from different sources in the world mix air before arriving at ear, requiring brain to estimate individual received mixture. Sounds produced by a given source often exhibit consistencies structure that might be useful for separating if they could learned. Here we show listeners rapidly learn abstract shared novel and use learned extract these appear mixtures. involvement of learning memory our ability hear one sound among...
Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants, but sacrifice control sound presentation, and therefore are not widely employed in hearing research. To help standardize online we introduce a brief psychophysical test for determining if experiment participants wearing headphones. Listeners judge which three pure tones is quietest, with one presented 180° out phase across stereo channels. This task intended to be easy...
Abstract Background music is widely used to sustain attention, but little known about what musical properties aid attention. This may be due inter-individual variability in neural responses music. Here we find that with amplitude modulations added at specific rates can attention differentially for those varying levels of attentional difficulty. We first tested the hypothesis strong modulation would improve sustained and found it did so when occurred early experiment. Rapid elicited greater...

Auditory scenes often contain multiple sound sources, but typically one is of particular interest and must be selected for further processing. This “cocktail party problem” especially difficult when sources are similar change over time (e.g., speakers the same gender). To study this situation, we introduced a paradigm in which listeners attempt to follow two synthetic voices that vary randomly several feature dimensions f0, f1, f2). Psychophysical results from task suggest human employ...
Auditory scene analysis depends on knowledge of natural sound structure, but little is known about how source-specific structures might be learned and applied. We explored whether listeners internalize “schemas”—the abstract structure shared by different occurrences the same type source—during cocktail-party listening. measured ability to detect one two concurrent “melodies” that did not differ in mean pitch (nor timbre), ensuring only these melodies over time could used distinguish them....
Background music is known to affect performance on cognitive tasks, possibly due temporal modulations in the acoustic signal, but little about how should be designed aid performance. Since modulation has been shown shape neural activity networks, we chose test effects of sustained attention, which requires these networks and a common ingredient for success across many tasks. To understand specific aspects background influence manipulated rate depth amplitude imposed otherwise identical...
