Learning Phonemes With a Proto-Lexicon
Before the end of the first year of life, infants begin to lose the ability to perceive distinctions between sounds that are not phonemic in their native language. It is typically assumed that this developmental change reflects the construction of language-specific phoneme categories, but how these categories are learned largely remains a mystery. Peperkamp, Le Calvez, Nadal, and Dupoux (2006) ...
متن کاملLearning Phonemes Without Minimal Pairs
The question addressed by this research is how humans acquire the internalized, mental categories that reflect the phonemes of their language. That humans have such categories is evidenced by the fact that, for example, English speakers immediately recognize pear and bear as being different words. This immediate realization is independent of the fact that these two words have different meanings...
متن کاملLearning 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 کاملBottom-Up Learning of Phonemes: A Computational Study
We present a computational evaluation of a hypothesis according to which distributional information is su cient to acquire allophonic rules (and hence phonemes) in a bottom-up fashion. The hypothesis was tested using a measure based on information theory that compares distributions. The test was conducted on several arti cial language corpora and on two natural corpora containing transcriptions...
متن کاملFuzzy paraphrases in learning word representations with a lexicon
We figure out a trap that is not carefully addressed in the previous works using lexicons or ontologies to train or improve distributed word representations: For polysemous words and utterances changing meaning in different contexts, their paraphrases or related entities in a lexicon or an ontology are unreliable and sometimes deteriorate the learning of word representations. Thus, we propose a...
