Increasing use of mobile devices for information access brings with it a demand for robust speech recognition. An important way in which speech recognition system performance can be improved is through use of dialogue strategies to handle the situation in which the system fails to recognise the user’s utterance. In the work described here, the case is made for combining multiple speech recognis...

Abstract Objectives First, to see whether previous studies showing a limited capacity spontaneously evoke the past and future of present moment (diachronic tendency) prevalence mental images over inner speech (thinking style) in individuals with autism spectrum disorder could be replicated belonging broader phenotype. Second, test hypothesis that thinking have more diachronic tendency compared ...

Telephone systems commonly transmit narrowband (NB) speech with an audio bandwidth limited to the traditional telephone band of 300-3400 Hz. To improve the quality and intelligibility of speech degraded by narrow bandwidth, researchers have tried to standardize the telephonic networks by introducing wideband (50-7000 Hz) speech codecs. Wideband (WB) speech transmission requires the transmission...

The functional neuroanatomy of speech processing has been difficult to characterize. One major impediment to progress has been the failure to consider task effects when mapping speech-related processing systems. We summarize a dual-stream model of speech processing that addresses this situation. In this model, a ventral stream processes speech signals for comprehension, and a dorsal stream maps...

Disturbing factors like reverberation or ambient noise can impair speech recognition and raise the listening effort needed for successful communication in daily life. Situations with high listening effort are thought to result in increased stress for the listener. The aim of this study was to explore possible measures to determine listening effort in situations with varying background noise and...

In everyday life, speech is often accompanied by a situationspecific acoustic cue; a hungry bark as you ask ‘Has anyone fed the dog?’. This paper investigates the effect such cues have on speech intelligibility in noise and evaluates their interaction with the established effect of situation-specific semantic cues. This work is motivated by the introduction of new object-based broadcast formats...

This study investigated the effect of intensity on pitch in electric hearing and its relationship to the speech perception ability of cochlear implantees. Subjects were 13 adult users of the Nucleus 22 cochlear implant system, using either the Spectra22 or ESPrit22 speech processor and the SPEAK speech processing strategy. A multidimensional scaling technique was employed. Speech perception was...

The output of a speech recognition system is not always ideal for subsequent downstream processing, in part because speakers themselves often make mistakes. A system would accomplish speech reconstruction of its spontaneous speech input if its output were to represent, in flawless, fluent, and content-preserving English, the message that the speaker intended to convey. These cleaner speech tran...

In real-world environments, speech often occurs simultaneously with acoustic interference, such as background noise or reverberation. The interference usually leads to adverse effects on speech perception, and results in performance degradation in many speech applications, including automatic speech recognition and speaker identification. Monaural speech separation and processing aim to separat...

Speech produced in noise (or Lombard speech) is characterized by increased vocal effort, but also by amplified lip gestures. The current study examines whether this enhancement of visible speech cues may be sought by the speaker, even unconsciously, in order to improve his visual intelligibility. One subject played an interactive game in a quiet situation and then in 85dB of cocktail-party nois...
