This article describes a new Speaker Discrimination System (SDS), which is a part of an overall project called Audio Documents Indexing based on a Speaker Discrimination System (ADISDS). Speaker discrimination consists in checking whether two speech segments come from the same speaker or not. This research domain presents an important field in biometry, since the voice remains an important feat...

vestibular schwannoma is the most common tumor of the posterior fossa of the skull. patients referred with the primary otologic symptoms such as hearing loss, tinnitus, vertigo, imbalance, and the cranial nerve palsy. thirty-three patients were operated and treated by a team of otolaryngologist and neurosurgeon, anudiometrist, and internist. patients'chiefcomplaint was due to 94% hearing l...

For assessment of hearing assistance devices, a speaker discrimination test was developed. The speech material was drawn from a “Japanese phonetically balanced word speech database” which was developed by Electrotechnical Laboratory, Japan (ETL-WD corpus). The test consisted of ten words spoken by ten speakers. The words were selected considering familiarity, and the speakers were selected cons...

The problem of speech, music and music with songs discrimination in telephony with handsets variability is addressed in this paper. Two systems are proposed. The first system uses three Gaussian Mixture Models (GMM) for speech, music and songs respectively. Each GMM comprises 8 Gaussians trained on very short sessions. Twenty six speakers (13 females, 13 males) have been randomly chosen from th...

We conducted a retrospective outcomes review of the charts of 22 patients with Ménière's disease who were treated with intratympanic perfusion of methylprednisolone and/or dexamethasone. Outcomes were determined by subjective assessment of vertigo control and by objective changes in audiometric pure-tone average (PTA) and speech discrimination score (SDS). These evaluations were made at the fir...

OBJECTIVES/HYPOTHESIS To examine the relationship between bony cochlear nerve canal (BCNC) width, degree of hearing loss, and speech discrimination in children with unilateral sensorineural hearing loss (USNHL). STUDY DESIGN Retrospective chart review (case-control study). METHODS Audiometric database was cross-referenced with radiologic database at pediatric tertiary care facility to ident...

Transcranial direct current stimulation (tDCS) can alter cortical excitability, and has been effective in treating some neurological disorders. This case report describes the use of tDCS in a 13-year-old female who developed bilateral hearing impairment after brainstem encephalitis when she was 6 years old. Her auditory function was more impaired in her right ear than her left. Anodal stimulati...

The effects of aging on decision time were examined in a brightness discrimination experiment with young and older subjects (ages, 60-75 years). Results showed that older subjects were slightly slower than young subjects but just as accurate. Ratcliff's (1978) diffusion model was fit to the data, and it provided a good account of response times, their distributions, and response accuracy. There...
