“…In this context, Tsuji et al (2012) explored Japanese adults' production and perception of plosive sequences containing a labial consonant (/p/ or /b/) and a coronal consonant (/t/ or /d/). The results revealed that Japanese adults have an LC bias in production, supporting the explanations in terms of articulatory constraints (MacNeilage & Davis, 2000a;MacNeilage et al, 2000;Sato et al, 2007). However, Japanese adults did show a perceptual CL bias for these plosive sequences, showing the influence of language exposure on perceptual biases as had been previously suggested (Nazzi et al, 2009;Gonzalez-Gomez & Nazzi, 2012a,b,c).…”

“…Classically, the effect has been explained as the result of production constraints (Ingram, 1974;MacNeilage & Davis, 2000a;MacNeilage et al, 2000;Sato et al, 2007). In contrast, Nazzi et al (2009) and Gonzalez-Gomez and Nazzi (2012a) offered a perceptual explanation.…”

“…MacNeilage et al, 1999;MacNeilage & Davis, 2000b) and more recently at the perceptual level as well (Nazzi et al, 2009;Gonzalez-Gomez & Nazzi, 2012a,b,c). Authors have attributed this bias on the one hand to language-general articulatory constraints on production favoring LC sequences (Ingram, 1974;MacNeilage et al, 2000;MacNeilage & Davis, 2000a;Rochet-Capellan & Schwartz, 2005;Sato et al, 2007), and on the other hand to language-specific effects of linguistic exposure on perceptual acquisition, resulting in LC or CL biases depending on the statistical properties of the input (Nazzi et al, 2009;Gonzalez-Gomez & Nazzi, 2012a,b,c). However, all the acquisition studies on the perceptual bias had been conducted on a single linguistic population learning a language with a clear LC bias, French, and a CL bias was found in only one study on fricative sequences.…”

“…both /bete/ and /tebe/ shifted to /b'te/). Based on these results (extended to Japanese adults by Tsuji, Gonzalez-Gomez, Medina, Nazzi, & Mazuka, 2012), Sato, Vallee, Schwartz, and Rousset (2007) suggested that the LC bias might be explained by the higher articulatory stability of LC sequences compared with CL ones. It is important to emphasize that both articulatory explanations assume the existence of a language-general (that is, non-language specific) LC bias, predicting similar patterns across languages.…”

“…A second articulatory explanation known as the ''LabialCoronal Chunking Hypothesis'' was proposed by Sato, Vallee, Schwartz, and Rousset (2007). Their results from adult speeded articulation tasks showed that when French adults produce Consonant-Vowel-Consonant-Vowel sequences containing a labial (L) and a coronal (C) consonant at a fast articulatory rate, their productions tend to shift to Consonant-Consonant-Vowel sequences.…”

The role of the input on the development of the LC bias: A crosslinguistic comparison

a b s t r a c tPrevious studies have described the existence of a phonotactic bias called the Labial-Coronal (LC) bias, corresponding to a tendency to produce more words beginning with a labial consonant followed by a coronal consonant (i.e. ''bat'') than the opposite CL pattern (i.e. ''tap''). This bias has initially been interpreted in terms of articulatory constraints of the human speech production system. However, more recently, it has been suggested that this presumably language-general LC bias in production might be accompanied by LC and CL biases in perception, acquired in infancy on the basis of the properties of the linguistic input. The present study investigates the origins of these perceptual biases, testing infants learning Japanese, a language that has been claimed to possess more CL than LC sequences, and comparing them with infants learning French, a language showing a clear LC bias in its lexicon. First, a corpus analysis of Japanese IDS and ADS revealed the existence of an overall LC bias, except for plosive sequences in ADS, which show a CL bias across counts. Second, speech preference experiments showed a perceptual preference for CL over LC plosive sequences (all recorded by a Japanese speaker) in 13-but not in 7-and 10-month-old Japanese-learning infants (Experiment 1), while revealing the emergence of an LC preference between 7 and 10 months in French-learning infants, using the exact same stimuli. These crosslinguistic behavioral differences, obtained with the same stimuli, thus reflect differences in processing in two populations of infants, which can be linked to differences in the properties of the lexicons of their respective native languages. These findings establish that the emergence of a CL/LC bias is related to exposure to a linguistic input.

The labial–coronal effect revisited: Japanese adults say pata, but hear tapa

et al. 2012

View full text Add to dashboard Cite

The labial-coronal effect has originally been described as a bias to initiate a word with a labial consonant-vowel-coronal consonant (LC) sequence. This bias has been explained with constraints on the human speech production system, and its perceptual correlates have motivated the suggestion of a perception-production link. However, previous studies exclusively considered languages in which LC sequences are globally more frequent than their counterpart. The current study examined the LC bias in speakers of Japanese, a language that has been claimed to possess more CL than LC sequences. We first conducted an analysis of Japanese corpora that qualified this claim, and identified a subgroup of consonants (plosives) exhibiting a CL bias. Second, focusing on this subgroup of consonants, we found diverging results for production and perception such that Japanese speakers exhibited an articulatory LC bias, but a perceptual CL bias. The CL perceptual bias, however, was modulated by language of presentation, and was only present for stimuli recorded by a Japanese, but not a French, speaker. A further experiment with native speakers of French showed the opposite effect, with an LC bias for French stimuli only. Overall, we find support for a universal, articulatory motivated LC bias in production, supporting a motor explanation of the LC effect, while perceptual biases are influenced by distributional frequencies of the native language.

It is an old-standing debate in the field of speech communication to determine whether speech perception involves auditory or multisensory representations and processing, independently on any procedural knowledge about the production of speech units or on the contrary if it is based on a recoding of the sensory input in terms of articulatory gestures, as posited in the Motor Theory of Speech Perception. The discovery of mirror neurons in the last 15 years has strongly renewed the interest for motor theories. However, while these neurophysiological data clearly reinforce the plausibility of the role of motor properties in perception, it could lead in our view to incorrectly deemphasise the role of perceptual shaping, crucial in speech communication. The so-called Perception-for-Action-Control Theory (PACT) aims at defining a theoretical framework connecting in a principled way perceptual shaping and motor procedural knowledge in speech multisensory processing in the human brain. In this paper, the theory is presented in details. It is described how this theory fits with behavioural and linguistic data, concerning firstly vowel systems in human languages, and secondly the perceptual organization of the speech scene. Finally a neurocomputational framework is presented in connection with recent data on the possible functional role of the motor system in speech perception.Keywords: perceptuo-motor interaction; speech perception; vowel perception; perceptual organisation; multisensory interactions; neurocomputational model; dorsal route IntroductionIt is an old-standing debate in the field of speech communication to determine whether speech perception involves auditory or multisensory representations and processing, independently on any procedural knowledge about the production of speech units (for a review, Diehl et al., 2004); or on the contrary if it is based on a recoding of the sensory input in terms of articulatory gestures, as posited in the Motor Theory of Speech Perception (Liberman et al., 1962;Liberman and Mattingly 1985;Liberman & Whalen, 2000).

A Perceptual Correlate of the Labial-Coronal Effect

Abstract: Conclusion: This study demonstrates that the Labial-Coronal effect also occurs in the course of on-line speech processing. This result is interpreted in relation with theories assuming a link between perception and action in the human speech processing system.
