This paper explores packet loss recovery for automatic speech recognition (ASR) in spoken dialog systems, assuming an architecture in which a lightweight client communicates with a remote ASR server. Speech is transmitted with source and channel codes optimized for the ASR application, i.e., to minimize word error rate. Unequal amounts of forward error correction, depending on the data’s effect...

Phone-like acoustic models (AMs) used in large-vocabulary automatic speech recognition (ASR) systems are usually trained with speech collected from young adult speakers. Using such models, ASR performance may decrease by about 10% absolute when transcribing elderly speech. Ageing is known to alter speech production in ways that require ASR systems to be adapted, in particular at the level of ac...

Consanguineous marriage that defines as a union between biologically related persons has a variety of known deleterious correlations with factors that affect public health within human populations. To investigate the association between the mean of inbreeding coefficient (α) and incidence of leukemia, the present ecological study on 68 countries was carried out. Statistical analysis showed that...

This paper describes the new ASR system developed by the LIUM and analyzes the various origins of the significant drop of the word error rate observed in comparison to the previous LIUM ASR system. This study was made on the test data of the latest evaluation campaign of ASR systems on French broadcast news, called ESTER2 and organized in December 2008. For the same computation time, the new sy...

Psychophysiological research on emotion utilizes various physiological response measures to index activation of the defense system. Here we tested 1) whether acoustic startle reflex (ASR), skin conductance response (SCR) and heart rate (HR) elicited by highly arousing stimuli specifically reflect a defensive state and 2) the relation between resting heart rate variability (HRV) and affective re...

This study analyzed the relationship of individual differences in personality with habituation in the acoustic startle response (ASR). Data from nine trials in ASR to white noise bursts and a personality questionnaire based on the alternative big five personality approach were modelled with a latent growth curve (LCM) including intercept and slope habituation growth factors. There was a negativ...

This paper addresses the transmission channel impact on human-to-human speech communication quality as well as on ASR performance. Transmission channels include standard wireline or mobile telephone networks and IP-based networks, which can be operated via different types of user interfaces. In order to gain control over the transmission channel, a simulation model is developed. It implements a...

background: leukoaraiosis (la) or white matter thinning and rarefaction are common in stroke patients. this pilot double-center study was designed to evaluate la risk factors in stroke patients.   methods: this cross sectional study was conducted on 100 consecutive stroke patients in walter mackenzie hospital, canada and 100 consecutive stroke patients in valie-asr hospital , iran in 2004. diag...

Background & Aims: Esophageal and gastric cancers are among prevalent cancers in the world and it is believed that nitrate and nitrite contaminations of drinking water are important factors in increasing the risk of these cancers. This study was designed to determine the correlations between these factors and upper gastrointestinal cancers. Methods: In this ecologic study, mean concentrations o...

Background: This study was conducted to evaluate the epidemiological features of bone and soft cancers in Golestan province, Northern Iran from 2004 2016. Methods: is a descriptive cross-sectional study. All patients with primary tissue between 2016 were included. Data obtained population-based cancer registry (GPCR). We calculated age-standardized incidence rates (ASRs) reported per 100000 per...
