“…In fact, in Baese-Berk (2010), listeners trained in perception alone improve significantly in their ability to produce tokens. This finding is relatively common in the literature (see also Bradlow et al 1997, Bradlow et al, 1999, Lametti et al 2014. Similarly, given that ultimately perception and production must be coordinated in order for communication to succeed, there should be situations in which production could aid perception.…”

Spoken language requires individuals to both perceive and produce speech. Because both processes access lexical and sublexical representations, it is commonly assumed that perception and production involve cooperative processes. However, few studies have directly examined the nature of the relationship between the two modalities, particularly how producing speech influences speech perception. In a series of experiments, we examine the counter-intuitive finding that learning perceptual representations can be disrupted by producing tokens during training. We investigate whether this disruption can be alleviated by prior experience with the speech sounds, and whether the cause of the disruption is production of the particular sound being learned, or is a more general conflict between the production system and the system that develops new perceptual representations. Our results paint a more competitive relationship between perception and production than might be assumed and suggest that both demands inherent to production and cognitive demands modulate this relationship.

“…Lametti et al ., 2014; Shiller & Rochon, 2014). It is therefore conceivable that with longer, more varied exposure to extrinsic speech stimuli in naturalistic, social-conversational contexts, adaptive perceptual processes could drive long-term changes in speech output through a combination of vowel-extrinsic normalization and error-correction mechanisms in the speech motor system.…”

The extent to which the adaptive nature of speech perception influences the acoustic targets underlying speech production is not well understood. For example, listeners can rapidly accommodate to talker-dependent phonetic properties – a process known as vowel-extrinsic normalization – without altering their speech output. Recent evidence, however, shows that reinforcement-based learning in vowel perception alters the processing of speech auditory feedback, impacting sensorimotor control during vowel production. This suggests that more automatic and ubiquitous forms of perceptual plasticity, such as those characterizing perceptual talker normalization, may also impact the sensorimotor control of speech. To test this hypothesis, we set out to examine the possible effects of vowel-extrinsic normalization on experimental subjects’ interpretation of their own speech outcomes. By combining a well-known manipulation of vowel-extrinsic normalization with speech auditory-motor adaptation, we show that exposure to different vowel spectral properties subsequently alters auditory feedback processing during speech production, thereby influencing speech motor adaptation. These findings extend the scope of perceptual normalization processes to include auditory feedback and support the idea that naturally occurring adaptations found in speech perception impact speech production.

“…This experiment contributes to the growing body of research demonstrating that sensory adaptation in speech can influence motoric learning (Bradlow et al, 1997;Lametti et al, 2014a), and that motoric adaptation can affect perception of other speakers (Shiller et al, 2009;Lametti et al, 2014b). It is interesting that the remapping during production generalized to the CFC processes during perception, given that perceptual retuning is notoriously specific (Kraljic and Samuel, 2005;Reinisch et al, 2014).…”

Sensorimotor adaptation affects perceptual compensation for coarticulation

A given speech sound will be realized differently depending on the context in which it is produced. Listeners have been found to compensate perceptually for these coarticulatory effects, yet it is unclear to what extent this effect depends on actual production experience. In this study, whether changes in motor-to-sound mappings induced by adaptation to altered auditory feedback can affect perceptual compensation for coarticulation is investigated. Specifically, whether altering how the vowel [i] is produced can affect the categorization of a stimulus continuum between an alveolar and a palatal fricative whose interpretation is dependent on vocalic context is tested. It was found that participants could be sorted into three groups based on whether they tended to oppose the direction of the shifted auditory feedback, to follow it, or a mixture of the two, and that these articulatory responses, not the shifted feedback the participants heard, correlated with changes in perception. These results indicate that sensorimotor adaptation to altered feedback can affect the perception of unaltered yet coarticulatorily-dependent speech sounds, suggesting a modulatory role of sensorimotor experience on speech perception.
