High stimulus variability in nonnative speech learning supports formation of abstract categories: Evidence from Japanese geminates
High stimulus variability nonnative speech learning abstract categories Japanese geminates
2015/4/24
This study reports effects of a high-variability training procedure on nonnative learning of a Japanese geminate-singleton fricative contrast. Thirty native speakers of Dutch took part in a 5-day trai...
Listeners Retune Phoneme Categories Across Languages
speech perception perceptual learning foreign accent second language listening
2015/4/24
Native listeners adapt to noncanonically produced speech by retuning phoneme boundaries by means of lexical knowledge. We asked whether a second language lexicon can also guide category retuning and w...
The interrelation between acoustic context effects and available response categories in speech sound categorization

2015/4/20
In an investigation of contextual influences on sound categorization, 64 Peruvian Spanish listeners categorized vowels on an /i/ to /e/ continuum. First, to measure the influence of the stimulus range...
Supervised and Unsupervised Learning of Multidimensional Acoustic Categories

2015/4/7
Learning to recognize the contrasts of a language-specific phonemic repertoire can be viewed as forming categories in a multidimensional psychophysical space. Research on the learning of distributiona...
Learning phonetic categories by tracking movements
Learning phonetic categories tracking movements
2012/12/18
We explore in this study how infants may derive phonetic categories from adult input that are highly variable. Neural networks in the form of self-organizing maps (SOMs; Kohonen, 1989, 1995) were used...
CONTEXTUAL VARIABILITY AND INFANTS’ PERCEPTION OF TONAL CATEGORIES

2012/12/18
This paper reviews some of the major findings in infants’ perception of phonetic categories, including consonants, vowels and lexical tones. We discuss empirical evidence suggesting a development from...
