Method Complete psychometric functions for phoneme and word recognition scores at 8 signal-to-noise ratios from −15 dB to 20 dB were generated for the first 10, 20, and 25, as well as all 50, three-word presentations of the Tri-Word or Computer Assisted Speech Recognition Assessment (CASRA) Test (Gelfand, 1998) based on the results of 12 normal-hearing young adult participants from the original study. Results The psychometric functions for both phoneme and word scores were very similar and essentially overlapping for all set sizes. Performance on the shortened tests accounted for 98.8% to 99.5% of the full (50-set) test variance with phoneme scoring, and 95.8% to 99.2% of the full test variance with word scoring. Shortening the tests accounted for little if any of the variance in the slopes of the functions. Conclusions The psychometric functions for abbreviated versions of the Tri-Word speech recognition test using 10, 20, and 25 presentation sets were described and are comparable to those of the original 50-presentation approach for both phoneme and word scoring in healthy, normal-hearing, young adult participants.

The purpose of this research was to determine some of the effects of consonant recognition training on the speech recognition performance of hearing-impaired adults. Two groups of ten subjects each received seven hours of either auditory or visual consonant recognition training, in addition to a standard two-week, group-oriented, inpatient aural rehabilitation program. A third group of fifteen subjects received the standard two-week program, but no supplementary individual consonant recognition training. An audiovisual sentence recognition test, as well as tests of auditory and visual consonant recognition, were administered both before and ibltowing training. Subjects in all three groups significantly increased in their audiovisual sentence recognition performance, but subjects receiving the individual consonant recognition training improved significantly more than subjects receiving only the standard two-week program. A significant increase in consonant recognition performance was observed in the two groups receiving the auditory or visual consonant recognition training. The data are discussed from varying statistical and clinical perspectives.

Accuracy Rates

We report normative data from a large (N=307) sample of young adult participants tested with a computerized version of the long form of the classical Benton Facial Recognition Test (BFRT; Benton & Van Allen, 1968). The BFRT-c requires to match a target face photograph to one or three of 6 face photographs simultaneously presented. Percent accuracy at the BFRT-c (81%-83%) is below ceiling yet well above chance level, with little interindividual variance in this typical population sample, as expected from a sensitive clinical test. While split-half reliability on accuracy rates is relatively low due to the large variability in difficulty across items, correct response times (RTs) measured in this version – completed in 3 minutes on average - provide a reliable and critical complementary measure of performance at individual unfamiliar face matching. In line with previous observations from other measures, females outperform male participants at the BFRT-c, especially for female faces. In general, performance is also lower following lighting changes than head rotations, in line with previous studies emphasizing limited ability at matching pictures of unfamiliar faces with important variations in lighting direction. Overall, this normative data set supports the validity of the BFRT-c as a key component of a battery of tests identifying clinical impairments at individual face recognition such as observed in acquired prosopagnosia. However, beyond global indexes of performance based on accuracy rates only, this analysis strongly recommends full consideration of the time taken to match individual faces as well as the variability in performance across items.

Purpose The purpose of this study was to construct a recorded speech recognition threshold (SRT) test for Spanish-speaking children utilizing a picture board and a picture-pointing task. Design The Spanish Pediatric Speech Recognition Threshold (SPSRT) test was developed and validated in this study. Test construction steps included (a) stimulus selection, (b) assessment of familiarity, (c) digital recording, (d) creation of pictures that accurately depicted the target word from the stimulus set, and (e) validation of the test and recordings. SRTs were obtained from 24 Spanish-speaking children whose 1st language was Spanish. Results Normative data are presented that validate the SPSRT and establish the baseline relationship between the pure-tone average and the SRT obtained with the SPSRT. Results indicated that the SPSRT obtained using this test should be within 2–12 dB of an individual's pure-tone average for Spanish-speaking children with normal hearing and minimal hearing loss. Conclusions The SPSRT was developed and validated as a picture-pointing Spanish SRT test to be used with Spanish-speaking children. The 2-channel recording contains an English translation track, making this test easy to administer and interpret for clinicians without knowledge of Spanish.

The Rasch Model

Purpose The purpose of this study was to describe an attempt to apply item-response theory (IRT) and the Rasch model to construction of speech-recognition tests. A set of word-recognition test items applicable to children as young as 3 years old—with any level of hearing sensitivity, with or without using hearing devices—was developed. Method Test items were constructed through expert consultation and by reference to some established language corpora, validated with 121 participants with various degrees of hearing loss and 255 with typical hearing. IRT and the Rasch model were applied to evaluate item quality. Results Eighty disyllabic word items were selected in accordance with IRT. The speech-recognition abilities of the 376 young participants are reported. The IRT analyses on this set of data are also discussed. Conclusions A new set of speech-recognition test materials in Cantonese Chinese has been developed. Construction of short equivalent lists may be performed in accordance with IRT item qualities. Clinical applications of this test tool in the particular language population are discussed.

Speech Recognition In Noise

Background: Speech recognition abilities of adults and children using cochlear implants (CIs) are significantly degraded in the presence of background noise, making this an important area of study and assessment by CI manufacturers, researchers, and audiologists. However, at this time there are a limited number of fixed-intensity sentence recognition tests available that also have multiple, equally intelligible lists in noise. One measure of speech recognition, the AzBio Sentence Test, provides 10-talker babble on the commercially available compact disc; however, there is no published evidence to support equivalency of the 15-sentence lists in noise for listeners with normal hearing (NH) or CIs. Furthermore, there is limited or no published data on the reliability, validity, and normative data for this test in noise for listeners with CIs or NH. Purpose: The primary goals of this study were to examine the equivalency of the AzBio Sentence Test lists at two signal-to-noise ratios (SNRs) in participants with NH and at one SNR for participants with CIs. Analyses were also conducted to establish the reliability, validity, and preliminary normative data for the AzBio Sentence Test for listeners with NH and CIs. Research Design: A cross-sectional, repeated measures design was used to assess speech recognition in noise for participants with NH or CIs. Study Sample: The sample included 14 adults with NH and 12 adults or adolescents with Cochlear Freedom CI sound processors. Participants were recruited from the University of North Texas clinic population or from local CI centers. Data Collection and Analysis: Speech recognition was assessed using the 15 lists of the AzBio Sentence Test and the 10-talker babble. With the intensity of the sentences fixed at 73 dB SPL, listeners with NH were tested at 0 and −3 dB SNRs, and participants with CIs were tested at a +10 dB SNR. Repeated measures analysis of variance (ANOVA) was used to analyze the data. Results: The primary analyses revealed significant differences in performance across the 15 lists on the AzBio Sentence Test for listeners with NH and CIs. However, a follow-up analysis revealed no significant differences in performance across 10 of the 15 lists. Using the 10, equally-intelligible lists, a comparison of speech recognition performance across the two groups suggested similar performance between NH participants at a −3 dB SNR and the CI users at a +10 SNR. Several additional analyses were conducted to support the reliability and validity of the 10 equally intelligible AzBio sentence lists in noise, and preliminary normative data were provided. Conclusions: Ten lists of the commercial version of the AzBio Sentence Test may be used as a reliable and valid measure of speech recognition in noise in listeners with NH or CIs. The equivalent lists may be used for a variety of purposes including audiological evaluations, determination of CI candidacy, hearing aid and CI programming considerations, research, and recommendations for hearing assistive technology. In addition, the preliminary normative data provided in this study establishes a starting point for the creation of comprehensive normative data for the AzBio Sentence Test.

Post Implantation

Long-term (two-year post-implantation) speech recognition was evaluated of prelingually and postlingually deafened adult cochlear implant users who had received either a single or a multichannel device. The patient group comprised 8 pairs of patients matched according to the onset and duration of deafness; in each pair one patient had an extra-cochlear single-channel implant and one had an intra-cochlear multichannel implant. A CDT (Continuous Discourse Tracking) test and a closed-set speech recognition test were used for speech recognition. The results of the postlingually deafened pairs of patients showed that the multichannel implant was superior to the single-channel implant, which is in agreement with other studies. In the pairs of prelingually deafened adult patients, the multichannel system was not found to be superior. This warrants further study and further application of single-channel implants in prelingually deafened patients.
