Optimization under ecological realism reproduces signatures of human speech perception
… in machine learning have made real-world perception tasks feasible for computers, in many cases approaching levels of performance similar to those of humans. In particular, optimizing models for ecologically realistic training datasets has helped to yield more human-like model results. In …

Robust speech recognition based on spectro-temporal processing
… for enhancing the robustness of automatic speech recognition systems (ASR) in adverse acoustical conditions. Recent physiological and psychoacoustical findings indicate that spectro-temporal processing plays an important role in human speech perception. Therefore, sigma-pi cells and Gabor …

A verification experiment of the second formant transition feature as a perceptual cue in natural speech
… features that are used as perceptual cues in human speech perception. A brief history of this research is given, with emphasis on one important feature, the second formant (F2) transition. A review of historical arguments made for and against its role in the perception of speech, as well as …

Processing Methods for the Detection of Landmark Acoustic Cues
This paper presents work on an aspect of a new speech analysis system for lexical access, which is based on the concept of individual acoustic cues in the speech signal such as Landmarks, which are abrupt changes in the spectrum due to articulatory events associated with vowels and consonants. It …

Dealing with linguistic mismatches for automatic speech recognition
Recent breakthroughs in automatic speech recognition (ASR) have resulted in a word error rate (WER) on par with human transcribers on the English Switchboard benchmark. However, dealing with linguistic mismatches between the training and testing data is still a significant challenge that remains …

Detection of consonant voicing : a module for a hierarchical speech recognition system
… thesis, a method for designing a hierarchical speech recognition system at the phonetic level is presented. The system employs various component modules to detect acoustic cues in the signal. These acoustic cues are used to infer values of features that describe segments. Features are …

A theory of speech perception in normal and hearing-impaired ears
… the longstanding problem of understanding human speech perception. We aim to study speech perception and decode perceptual cues in speech by conducting psychoacoustic experiments on several subjects by presenting them with nonsense consonant-vowel (CV) syllables in various kinds of masking …

Modeling and Evaluating Human Sound Localization in the Natural Environment
Humans locate sounds in their environment to avoid danger and identify objects of interest. In a ten-minute bike ride, a person might take note of a car approaching from behind, a tree where a bird is singing, and pedestrians walking from around a blind corner. Research on human sound localization …
