A computational analysis of uniqueness points in auditory word recognition.
نویسنده
چکیده
To determine the extent to which words in isolation may be recognized prior to their offsets, uniqueness points or optimal discrimination points were computed for all words in a 20,000oword computerized lexicon with more than two phonemes. The results of this analysis revealed that the frequency-weighted probability of a word’s diverging from all other words in the lexicon prior to the last phoneme was only .39. This finding suggests that an optimally efficient strategy of word recognition may be severely limited in scope due to structural properties of the mental lexicon.

Correlation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...

متن کاملProbability and surprisal in auditory comprehension of morphologically complex words.
Two auditory lexical decision experiments document for morphologically complex words two points at which the probability of a target word given the evidence shifts dramatically. The first point is reached when morphologically unrelated competitors are no longer compatible with the evidence. Adapting terminology from Marslen-Wilson (1984), we refer to this as the word's initial uniqueness point ...

Background: The main result of hearing impairment is reduction of speech perception. Patient with auditory neuropathy can hear but they can not understand. Their difficulties have been traced to timing related deficits, revealing the importance of the neural encoding of timing cues for understanding speech. Objective: In the present study psychoacoustic perception (minimal noticeable differen...
