Revisiting Word Neighborhoods for Speech Recognition
نویسندگان
چکیده
Word neighborhoods have been suggested but not thoroughly explored as an explanatory variable for errors in automatic speech recognition (ASR). We revisit the definition of word neighborhoods, propose new measures using a fine-grained articulatory representation of word pronunciations, and consider new neighbor weighting functions. We analyze the significance of our measures as predictors of errors in an isolated-word ASR system and a continuous-word ASR system. We find that our measures are significantly better predictors of ASR errors than previously used neighborhood density measures.

متن کاملAll Neighborhoods are not Created Equal: The Phonological P-Metric and Spoken Word Recognition
A great deal of work has shown that the size of the phonological neighborhood affects the speed and accuracy of spoken word recognition. Words with many similar sounding words (i.e., a dense neighborhood) are recognized more slowly and less accurately than words with few similar sounding words (i.e., a sparse neighborhood). However, little work has examined the structural differences that may e...

متن کاملWord length and lexical competition: longer is the same as shorter.
Neighborhood density refers to the number of words that sound similar to a given word. Previous studies have found that neighborhood density influences the recognition of spoken words (Luce & Pisoni, 1998); however, this work has focused almost exclusively on monosyllabic words in English. To investigate the effects of neighborhood density on longer words, bisyllabic words varying in neighborho...
متن کاملCorrelation 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 ...
