this paper introduces a novel approach to improve performance of speech recognition systems using a combination of features obtained from speech reconstructed phase space (rps) and frequency domain analysis. by choosing an appropriate value for the dimension, reconstructed phase space is assured to be topologically equivalent to the dynamics of the speech production system, and could therefore ...

Language and action systems are highly interlinked. A critical piece of evidence is that speech and its accompanying gestures are tightly synchronized. Five experiments were conducted to test 2 hypotheses about the synchronization of speech and gesture. According to the interactive view, there is continuous information exchange between the gesture and speech systems, during both their planning ...

This paper presents a delayed instantaneous demixer (DID) for speech signal separation from real recordings. Based on the fact that the original signals are colored and mutually uncorrelated, a simple algorithm is derived to estimate the parameters of the demixer. This algorithm consists of two parts: a grid searching method to estimate time delays and an alternating projection method to estima...

30 intermediate Chinese English learners participated in two experiments which address the issue of first language negative phonological transfer on second language word identification and production. In Experiment 1, the subjects performed an auditory priming task. In Experiment 2, the subjects completed a pronunciation task, in which they were asked to read words containing “th” and some fill...

Visual speech information helps listeners perceive speech in noise. The cues underpinning this visual advantage appear to be global and distributed, and previous research hasn’t succeeded in pinning down simple dimensions to explain the effect. In this study we focus on the temporal aspects of visual speech cues. In comparison to a baseline of auditory only sentences mixed with noise, we tested...

Brain imaging methods have contributed to shed light on the possible mechanisms of recovery and cortical reorganization after early brain insult. The idea that a functional left hemisphere is crucial for achieving a normalized pattern of language development after left perinatal stroke is still under debate. We report the case of a 3.5-year-old boy born at term with a perinatal ischemic stroke ...
