Vocoded Speech

Purpose An increasing number of individuals with residual or even normal contralateral hearing are being considered for cochlear implantation. It remains unknown whether the presence of contralateral hearing is beneficial or detrimental to their perceptual learning of cochlear implant (CI)–processed speech. The aim of this experiment was to provide a first insight into this question using acoustic simulations of CI processing. Method Sixty normal-hearing listeners took part in an auditory perceptual learning experiment. Each subject was randomly assigned to one of three groups of 20 referred to as NORMAL, LOWPASS, and NOTHING. The experiment consisted of two test phases separated by a training phase. In the test phases, all subjects were tested on recognition of monosyllabic words passed through a six-channel “PSHC” vocoder presented to a single ear. In the training phase, which consisted of listening to a 25-min audio book, all subjects were also presented with the same vocoded speech in one ear but the signal they received in their other ear differed across groups. The NORMAL group was presented with the unprocessed speech signal, the LOWPASS group with a low-pass filtered version of the speech signal, and the NOTHING group with no sound at all. Results The improvement in speech scores following training was significantly smaller for the NORMAL than for the LOWPASS and NOTHING groups. Conclusions This study suggests that the presentation of normal speech in the contralateral ear reduces or slows down perceptual learning of vocoded speech but that an unintelligible low-pass filtered contralateral signal does not have this effect. Potential implications for the rehabilitation of CI patients with partial or full contralateral hearing are discussed.

Major Focus

The concluding chapter argues that perceptual learning has relevance for philosophy far beyond philosophy of mind—in epistemology, philosophy of science, and social philosophy, among other domains. The goal of this chapter is to extend one major focus of the book, which is to identify the scope of perceptual learning. Chapters 3 through 7 argued that perceptual learning occurs in all sorts of domains in the philosophy of mind, including natural kind recognition, sensory substitution, multisensory perception, speech perception, and color perception. This chapter extends that scope beyond philosophy of mind and offers some initial sketches of ways in which we can apply knowledge of perceptual learning to those domains.

Age Related Hearing Loss

Challenging listening situations (e.g., when speech is rapid or noisy) result in substantial individual differences in speech perception. We propose that rapid auditory perceptual learning is one of the factors contributing to those individual differences. To explore this proposal, we assessed rapid perceptual learning of time-compressed speech in young adults with normal hearing and in older adults with age-related hearing loss. We also assessed the contribution of this learning as well as that of hearing and cognition (vocabulary, working memory, and selective attention) to the recognition of natural-fast speech (NFS; both groups) and speech in noise (younger adults). In young adults, rapid learning and vocabulary were significant predictors of NFS and speech in noise recognition. In older adults, hearing thresholds, vocabulary, and rapid learning were significant predictors of NFS recognition. In both groups, models that included learning fitted the speech data better than models that did not include learning. Therefore, under adverse conditions, rapid learning may be one of the skills listeners could employ to support speech recognition.

Novel Words

To determine how familiarity with a talker's voice affects perception of spoken words, we trained two groups of subjects to recognize a set of voices over a 9-day period One group then identified novel words produced by the same set of talkers at four signal-to-noise ratios Control subjects identified the same words produced by a different set of talkers The results showed that the ability to identify a talker's voice improved intelligibility of novel words produced by that talker The results suggest that speech perception may involve talker-contingent processes whereby perceptual learning of aspects of the vocal source facilitates the subsequent phonetic analysis of the acoustic signal

Learning Mechanism

This chapter details the role perceptual learning plays in speech perception and argues that the evidence does not show that meanings come to be represented in our perception upon learning a new language. Specifically, it outlines the role of the perceptual learning mechanism of differentiation in speech perception. Through differentiation, we come to parse features of a language, including phonemes that we had not previously differentiated. The chapter critically evaluates Casey O’Callaghan’s and Berit Brogaards’s arguments for and against the view that meanings come to be represented in our perception upon learning a new language. It argues that the evidence from perceptual learning does not support the conclusion that meanings come to be represented in our perception.
