Research has yielded a relationship between pitch matching and pitch discrimination. Good pitch matchers tend to be good pitch discriminators and are often judged to be vocally talented. Otoacoustic emission suppression measures the function of the efferent auditory system which may affect accuracy for pitch matching and pitch discrimination. Formally trained musicians show pitch matching and pitch discrimination superior to those of nonmusicians and have greater efferent otoacoustic emission suppression than nonmusicians. This study investigated the relationship among pitch matching, pitch discrimination, and otoacoustic emission suppression in individuals with no formal musical training and who showed varied pitch matching and pitch discrimination. Analysis suggested a significant relationship between pitch matching and pitch discrimination but not between otoacoustic emission suppression and pitch matching and pitch discrimination. Findings are presented in the context of previous research indicating a significant relationship between otoacoustic emission suppression and musical talent in trained musicians.

AbstractThe McGurk effect is widely used as a measure of multisensory integration during speech perception. Two observations have raised questions about the relationship between the effect and everyday speech perception. First, there is high variability in the strength of the McGurk effect across different stimuli and observers. Second, there is low correlation across observers between perception of the McGurk effect and measures of everyday speech perception, such as the ability to understand noisy audiovisual speech. Using the framework of the causal inference of multisensory speech (CIMS) model, we explored the relationship between the McGurk effect, syllable perception, and sentence perception in seven experiments with a total of 296 different participants. Perceptual reports revealed a relationship between the efficacy of different McGurk stimuli created from the same talker and perception of the auditory component of the McGurk stimuli presented in isolation, either with or without added noise. The CIMS model explained this high stimulus-level correlation using the principles of noisy sensory encoding followed by optimal cue combination within a representational space that was identical for McGurk and everyday speech. In other experiments, CIMS successfully modeled low observer-level correlation between McGurk and everyday speech. Variability in noisy speech perception was modeled using individual differences in noisy sensory encoding, while variability in McGurk perception involved additional differences in causal inference. Participants with all combinations of high and low sensory encoding noise and high and low causal inference disparity thresholds were identified. Perception of the McGurk effect and everyday speech can be explained by a common theoretical framework that includes causal inference.

The considerable variability in speech perception performance among cochlear implant patients makes it difficult to compare the effectiveness of different speech processing strategies. One result is that optimal individualized processor parameter setting is not always achieved. This paper investigates the relationship between place pitch discrimination ability and speech perception to establish whether pitch ranking could be used as an aid in better patient-specific fitting of processors. Three subjects participated in this study. Place pitch discrimination ability was measured and this information was used to design new channel to electrode allocations for each subject. Several allocations were evaluated with speech tests with consonant, vowel and sentence material. It is shown that there is correlation between the perceptual pitch distance between electrodes and speech perception performance. The results indicate that pitch ranking ability might be used both as an indicator of  the speech perception potential of an implant user and in the choice of better electrode configurations.
