HENNIG, Tais Regina; VAUCHER, Ana Valéria de Almeida  e  COSTA, Maristela Julio. Development and validation of lists of disyllabic words for speech audiometry testing. Audiol., Commun. Res. [online]. 2018, vol.23, e1915.  Epub 13-Dez-2018. ISSN 2317-6431.  http://dx.doi.org/10.1590/2317-6431-2017-1915.

Purpose

To compose a bank of dissyllabic words to develop equivalent disyllabic lists, perform content validation, obtain evidence of reliability and digitally record these lists to determine the Speech Recognition Percentage Index (SRPI) in order to complement the set of materials available for this evaluation.

Methods

We used disyllabic, paroxytone nouns, which were submitted to content validation, which included assessment of familiarity, appropriateness and auditory recognition by expert and non-expert raters. Lists of disyllabic words (with 25 words each) were developed from the words selected after content validation, and the equivalence search of these lists was carried out to collect evidence of reliability for the proposed new test instrument.

Results

The first version of the word bank was composed of 442 disyllables; 198 of them were considered to be familiar by most raters, and 176 were deemed as appropriate; after auditory recognition, 172 words were kept in the word bank, distributed into six lists, with 25 words in each one. Among these lists, only one differed from the others while the other five were considered to be equivalent, and were named LD-A, LD-B, LD-C, LD-D and LD-E, and recorded in digital format onto a Compact Disc.

Conclusion

Five lists of disyllabic words were considered as equivalent, named LD-A, LD-B, LD-C, LD-D and LD-E lists. They were digitally recorded and made available with satisfactory evidence of validity and reliability, to complement the set of available speech materials for SRPI assessment.
