Disease relevance of Speech Perception

• The absence of the ERP in contrast, indicated profound hearing disability evidenced by profound hearing loss and/or extremely poor speech perception [1].
• CONCLUSION: Four intratympanic injections of methylprednisolone improved pure-tone average or speech discrimination scores for a subset of sudden hearing loss subjects that failed to benefit from oral steroids [2].
• Therefore the clinically available quinoxaline dione caroverine provides a new approach to a successful treatment of tinnitus, sudden hearing loss and speech discrimination disorders in presbyacusis [3].

Psychiatry related information on Speech Perception

• After taking into account other factors which are known to affect language development and speech perception in children with impaired hearing, no significant differences were found between the 15 children where connexin 26 was known to be the cause of deafness and the other 37 children in the study [4].
• A comparison was made between speech recognition performance in conditions of quiet and babble (Speech Perception in Noise Test) and items from a self-assessment scale concerned with communication ability in quiet and noise (Understanding Speech section of Hearing Performance Inventory) [5].
• Of the few auditory perception tests presently available in Italian, the following were examined: namely, EARS (Evaluation of Auditory Responses to Speech) battery, on the one hand, and the Italian version of the ESP (Early Speech Perception), GASP (Glendonald Auditory Screening Procedure) [6].
• Changes in auditory threshold, psychophysical tuning curves, and speech perception (in both quiet and noise) were monitored over a 3-hr period following the ingestion of glycerol [7].
• Members of a Dutch DFNA13/COL11A2 family were evaluated with pure tone audiometry, stapedial reflexes, otoacoustic emissions, loudness scaling, difference limen for frequency, gap detection, and speech perception in quiet and noise [8].

High impact information on Speech Perception

• In order to specify the topography of the assumed cerebellar speech perception mechanism, a functional magnetic resonance imaging study was performed using the German lexical items "Boden" ([bodn], Engl. "floor") and "Boten" ([botn], "messengers") as test materials [9].
• Hearing was measured by the Speech Perception in Noise test; cognition was measured by two parts of the Wechsler Memory Scale and by the Jacobs Cognitive Screening Test, an oral screening instrument [10].
• Right hemisphere speech perception revealed by amobarbital injection and electrical interference [11].
• METHODS: Consecutive, unilateral, intracarotid sodium amobarbital injections and left hemispheric electrical interference mapping were used to determine lateralization and localization of speech perception, measured as syllable discrimination [11].
• If such processing of frequency change is important for understanding speech, then this observation of a specific central hearing defect may help to explain poor speech discrimination in some patients with MS who have normal audiograms [12].

Chemical compound and disease context of Speech Perception

• OBJECTIVE: This study compared speech perception benefits in adults implanted with the HiResolution (HiRes) Bionic Ear who used both conventional and HiRes sound processing [13].
• OBJECTIVE: The purpose of this article is to present psychophysical data for 40 Nucleus 24 Contour adult patients with 1 mo of device experience and speech perception results for a group of 56 adult patients with 3 mo experience using the Nucleus 24 Contour cochlear implant system [14].
• The post-treatment pure-tone average and speech discrimination score for the gentamicin group were 68.8 dB and 49.3%, respectively [15].
• No significant group mean difference in speech perception scores was found in comparing the clinical MAP with the streamlined MAPs based on a single interpolated T- or C-level profile created from five behavioral measures [16].
• METHODS: The Iowa Matrix Closed Set Sentence test, connected discourse tracking, categories of auditory performance, and speech intelligibility rating were used to assess the speech perception (closed and open set) and speech intelligibility of the children with implants [17].

Biological context of Speech Perception

• Previous studies have found that the P2 component of the auditory event-related potential (ERP) increases after speech discrimination training [18].
• OBJECTIVE: To evaluate the new Clarion CII cochlear implant with the perimodiolar HiFocus electrode array, including both speech perception outcomes and the device's capabilities of measuring the electrically evoked compound action potential (eCAP) of the auditory nerve (Neural Response Imaging, NRI) [19].

Anatomical context of Speech Perception

• Gadolinium-DTPA-enhanced magnetic resonance imaging (MRI) of the posterior cranial fossa portrayed an intracanalicular tumour image (2-3 mm), and the pure tone average (PTA) and speech discrimination score (SDS) values were 65 dB and 60 per cent, respectively [20].
• This paper studies the changes in speech discrimination following stapes surgery in patients with advanced otosclerosis [21].

Gene context of Speech Perception

• Language and speech perception outcomes in hearing-impaired children with and without connexin 26 mutations [4].
• Speech discrimination and phonological working memory in children with ADHD [22].
• In this context, the exploration of visual and audiovisual speech perception in WS is of interest [23].
• Mercury is known to cause sensorineural hearing loss and impaired speech perception [24].
• Electrode depth, together with the duration of deafness, hearing aid usage, pre-operative speech perception score and pre-operative pure-tone averages were independent variables in a forward stepwise multiple regression analysis, where the dependent variables were postoperative CNC words and CNC phonemes [25].

Analytical, diagnostic and therapeutic context of Speech Perception

• METHODS: The Iowa Matrix Closed Set Sentence Test and Connected Discourse Tracking were used to assess closed- and open-set speech perception, respectively, without lip reading [26].
• The audiological studies included pure tone audiogram, SISI test, Bekesy audiometry, glycerol (or urea) test, speech discrimination test, and electrocochleography [27].
• The infrequent complications of immediate and delayed sensorineural losses with impaired speech discrimination are certain to be reduced further in incidence by the increasing adoption of small fenestra techniques with piston prostheses and tissue seals [28].
• We report 25 consecutive stapedectomy cases in which most of the one-week postoperative audiograms of stapedectomized ears revealed a mid- and high-frequency sensorineural pure-tone loss and a drop in the standard speech discrimination scores [29].
• Pure tone audiometry and speech audiometry showed that during the nine-year interval, her 60 dB flat sensorineural hearing loss and speech perception thresholds had remained almost unchanged [30].
