Disease relevance of Speech Intelligibility

• Spectral feature enhancement for people with sensorineural hearing impairment: effects on speech intelligibility and quality [1].
• This study compared and contrasted results on pure tone audiometry, acoustic reflexes, and the Pediatric Speech Intelligibility Test in children with either documented or suspected central auditory dysfunction [2].
• METHODS: The study assessed 16 implanted children who were deafened by cytomegalovirus, using the Iowa Closed Sentence Test and Speech Intelligibility Rating [3].
• A mild dysarthria with ataxic and LMN components was identified, although overall speech intelligibility was not affected [4].

High impact information on Speech Intelligibility

• Speech intelligibility in quiet and CCITT noise from the side (+/-90 degrees ) was assessed using the German HSM sentence test and was significantly better when using bilateral CI in comparison with either unilateral CI, mainly due to a head shadow effect [5].
• CONCLUSIONS: Test results demonstrate speech-to-noise ratio has a significant effect on speech intelligibility of the CAT items under all conditions [6].
• RESULTS: Improvement in function including speech intelligibility was seen following the intrathecal baclofen trial [7].
• These corrected noise levels were then used to calculate an Articulation Index using the Speech Intelligibility Index (SII, ) [8].
• In Experiment 2 the hearing-impaired subjects showed a significant preference for the hearing aid setting with a long release time (4 sec) and a low compression threshold (20 dB SPL), both with regard to sound quality and speech intelligibility [9].

Biological context of Speech Intelligibility

• Fourteen experienced users of bone-anchored hearing aids conducted paired comparisons of sound quality and speech intelligibility for 6 and 4 different stimuli respectively in the Classic 300 and a bone-conduction hearing aid with a steel clip [10].

Associations of Speech Intelligibility with chemical compounds

• L-Dopa had a poor effect whereas bilateral stimulation improved oral control and speech intelligibility [11].
• It remains to be demonstrated if the effects of levodopa on tongue strength and endurance correlate with alterations in speech intelligibility, articulation and respiration [12].
• The purpose of this investigation was to determine if speech intelligibility improved when divers made specific modifications to their speaking patterns while in a hyperbaric helium-oxygen (heliox) environment [13].
• Performance for Pediatric Speech Intelligibility (PSI) Format I and Format II sentences was significantly different in children between the ages of 3 and 6 years [14].

Gene context of Speech Intelligibility

• CONCLUSION: In pediatric cochlear implantees, GJB2-related deafness is a predictor of good speech intelligibility [15].
• The effect on speech intelligibility of sensorineural hearing-impaired listeners of two principal-component compression system implementations, compression of PC1 and compression of both PC1 and PC2, was compared to that of linear amplification (LA), independent compression of multiple bands (MBC), and wideband compression (WC) [16].
• Speech intelligibility was measured in quiet at three sound levels (50, 65, and 80 dB SPL), and speech reception thresholds (SRTs) in 12-talker babble were measured under monaurally and binaurally aided conditions, with the speech and babble both coincident and spatially separated [17].
• This study also indicated that measuring speech intelligibility at MCL approximated PB max (+/- 12 percent) only about two-third of the time [18].
• Open-set monosyllabic CNC word perception in quiet and Speech Intelligibility Test sentence perception in noise was evaluated at the end of each of the time intervals [19].

Analytical, diagnostic and therapeutic context of Speech Intelligibility

• Comparison of three hearing aid fittings using the Speech Intelligibility Rating (SIR) Test [20].
• Connexin 26 (GJB2) gene-related deafness and speech intelligibility after cochlear implantation [15].
