INTRODUCTION AND OBJECTIVE Hearing disorders among school-age children are a current concern. Continuing studies have been performed in Poland since 2008, and on 2 December 2011 the EU Council adopted Conclusions on the Early Detection and Treatment of Communication Disorders in Children, Including the Use of e-Health Tools and innovative Solutions. The discussion now focuses not only on the ef...

BACKGROUND The effects of stimulus material, lexical content, and response condition on dichotic speech recognition performance characteristics were examined for normal-hearing young adult listeners. No previous investigation has systematically examined the effects of stimulus material with constant phonetic content but varied lexical content across three response conditions typically used to e...

PURPOSE To evaluate a new nuclear cataract grading system which is intended as a surgical guidance system to predict lens hardness before cataract surgery. METHODS The new BCN 10 grading system consists of frontal and cross-sectional slit-lamp images of human eye lenses, ranging from a completely transparent lens nucleus to a totally black nuclear cataract. Validation was done with 9 observer...

Some statistical tests of randomness are made of the first 88062 binary digits (or equivalent in other bases) of Jn in various bases b, 2 g n g 15 (n square-free) with b = 2,4, 8, 16 and n = 2, 3, 5 with b = 3,5, 6, 7, and 10. The statistical tests are the y2 test for cumulative frequency distribution of the digits, the lead test, and the gap test. The lead test is an examination of the distanc...

Older adults with sensorineural hearing loss have greater difficulty understanding speech than younger adults with equivalent hearing (Gates & Mills, 2005). This increased difficulty may be related to the influence of peripheral, central auditory processing or cognitive deficits and although this has been extensively debated the relative contribution to speech understanding is equivocal (Workin...

The Trail Making Test and Digit Span are neuropsychological tests widely used to assess executive abilities following stroke. The Trails B and Digits Backward conditions of these tests are thought to be more sensitive to executive impairment related to frontal lobe dysfunction than the Trails A and Digits Forward conditions. Trails B and Digits Backward are also thought to be more sensitive to ...

This paper describes development of a real-time speech recognition system in Slovak for the voice-operated telephone services. The system is based on SPHINX2 platform. The decoder using Hidden Markov Models was trained on the SpeechDat-E Slovak database. It is speaker independent, large vocabulary, continuous speech real-time automatic speech recognition system. Test results are given for the t...

background and aim: digits are suitable materials for hearing assessment of wide range of patients including children and adults with various language abilities. single monosyllabic 1-10 digits in triplet formant have been used for measuring speech recognition threshold in signal-to-noise ratio. the purpose of this study was to determine signal-to-noise ratio (snr) needed for 50 percent correct...
