An experimental offline investigation of the performance of connected digits recognition was performed on children in the age range four to eight years. Poor performance using adult models was improved significantly by adaptation and vocal tract length normalisation but not to the same level as training on children. Age dependent models were tried with limited advantage. A combined adult and ch...

This paper addresses the problem of automatic speech recognition in the presence of interfering noise. It focuses on the Parallel Model Combination (PMC) scheme, which has been shown to be a powerful technique for achieving noise robustness. Most experiments reported on PMC to date have been on small, 10-50 word vocabulary systems. Experiments on the Resource Management (RM) database, a 1000 wo...

in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...

In this paper, variability of Lombard speech under different noise conditions and an adaptation method to the different Lombard speech are discussed. For this purpose, various kinds of Lombard speech are recorded under different conditions of noise injected into a earphone with controlled feedback of voice. First, DTW word recognition experiments using clean speech as a reference are performed ...

This paper presents the system of the UGENT IBCN team for the TAC KBP 2014 slot filling and cold start (slot filling variant) tasks. This was the team’s first participation in both tasks. The slot filling system uses distant supervision to generate training data combined with a noise reduction step, and two different types of classifiers. We show that the noise reduction step significantly impr...

Background:  High noises in the NICU are known to have negative effects on the health and wellness of hospitalized preterm infants. Various technologies for the care of preterm infants, extensive therapeutic interventions and communication between staff are among the causes of loud noise in these wards. The aim of this review article is to evaluate the effectiveness of noise reduction intervent...

the goal of this study was to evaluate word's in–service training of takfa project (development and use of information and communication technology plan) via ministry of jihade agricultural staff perspective. the methodological approach was survey research and the target population was one hundred (100) of staff in jihad agricultural ministry who had attended in word's in–service trai...
