Learning Phonetic Categories by Learning a Lexicon
Infants learn to segment words from fluent speech during the same period as they learn native language phonetic categories, yet accounts of phonetic category acquisition typically ignore information about the words in which speech sounds appear. We use a Bayesian model to illustrate how feedback from segmented words might constrain phonetic category learning, helping a learner disambiguate over...
متن کاملLearning phonetic categories by tracking movements.
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; ) were used to simulate unsupervised learning of Mandarin tones. In Simulation 1, we trained the SOMs with syllable-sized continuous F(0) contours, produced by multiple speakers in connected speech, and with the corresponding v...

متن کاملLearning Abstract Phonological from Auditory Phonetic Categories: An Integrated Model for the Acquisition of Language-Specific Sound Categories
We introduce a two-stage model for the perceptual acquisition of speech sound categories within the framework of Stochastic Optimality Theory and the Gradual Learning Algorithm [1]. During the first stage, learning of language-specific sound categories by infants is driven by distributional evidence in the linguistic input. This auditory-driven learning leads to a warping of the baby’s perceptu...
متن کاملRelating phonetic and phonological categories
. Recent proposals to treat phonetic representations as the semantic interpretation of phonological representations are technically problematic to implement. The main di culty is that phonological representations are discrete while phonetic representations are continuous which makes the standard method of describing semantic interpretation as a homomorphism between sortally equivalent algebras ...
