The contribution of consonants versus vowels to word recognition in fluent speech
Three perceptual experiments were conducted to test the relative importance of vowels vs. consonants to recognition of uent speech. Sentences were selected from the TIMIT corpus to obtain approximately equal numbers of vowels and consonants within each sentence and equal durations across the set of sentences. In experiments 1 and 2, subjects listened to (a) unaltered TIMIT sentences; (b) senten...
متن کاملInfants exposed to fluent natural speech succeed at cross-gender word recognition.
PURPOSE To examine the possibility that early signal-to-word form mapping capabilities are robust enough to handle substantial indexical variation in the realization of words. METHOD Two groups of 7.5-month-olds were tested with the Headturn Preference Procedure. Half of the infants were exposed to words embedded in passages spoken by their mothers and tested on lists of trained and novel iso...
متن کاملMultiple brain networks underpinning word learning from fluent speech revealed by independent component analysis
Although neuroimaging studies using standard subtraction-based analysis from functional magnetic resonance imaging (fMRI) have suggested that frontal and temporal regions are involved in word learning from fluent speech, the possible contribution of different brain networks during this type of learning is still largely unknown. Indeed, univariate fMRI analyses cannot identify the full extent of...
متن کاملWord embeddings for speech recognition
Speech recognition systems have used the concept of states as a way to decompose words into sub-word units for decades. As the number of such states now reaches the number of words used to train acoustic models, it is interesting to consider approaches that relax the assumption that words are made of states. We present here an alternative construction, where words are projected into a continuou...
متن کاملRAW: a real-speech model for human word recognition
In recent years computational models have become more and more important in testing processing mechanisms assumed to underlie human spoken-word recognition. Models like TRACE (McClelland & Elman, 1986) and Shortlist (Norris, 1994) have given us much insight in the effects of, for instance, competition between words in the mental lexicon and the use of lexical information during word recognition...
