Abstract

COSTA, Maristela Julio; SANTOS, Sinéia Neujahr dos; LESSA, Alexandre Hundertmarck  and  MEZZOMO, Carolina Lisboa. Proposal for implementing the Sentence Recognition Index in individuals with hearing disorders. CoDAS [online]. 2015, vol.27, n.2, pp.148-154. ISSN 2317-1782.  http://dx.doi.org/10.1590/2317-1782/20150000316.

Purpose:

To present and describe a new strategy and protocol for obtaining the Sentences Recognition Indexes (SRI), using the Lists of Phrases in Portuguese test (LPP), considering words in the analysis of responses; to analyze and compare the results using the previous and the new strategies by checking their applicability and suitability.

Methods:

To consider each word of the sentence, words were classified according to their importance: functional and content words, assigning them, respectively, two and one points. SRI were obtained in 33 normal hearing adults, and results were compared using the two strategies.

Results:

A new protocol was established. Each point corresponds to the following percentages in each list: 1B, 1.11%; 2B, 1.13%; 3B, 1.17%; 4B, 1.16%; 5B, 1.20%; and 6B, 1.11%. The median SRI obtained through usual and new strategies were, respectively, for the list 1B: 60 and 82.57%; 2B: 70 and 80.79%; 3B: 50 and 76.60%; 4B: 70 and 82.60%; 5B: 50 and 77.20%; and 6B: 60 and 82.14%. A significant difference was found when these strategies were compared.

Conclusion:

New strategy and protocol for evaluating the SRI were developed using the LPP test, considering each word of the sentence. When comparing the responses it was noticed that when considering each word in the sentence it is possible to scale, more detailed and less variability, the actual ability to recognize speech of each individual, the new strategy and protocol developed confirmed its applicability and suitability to assess Sentence Recognition Indexes in Quiet in individuals with hearing disorders in a specific listening condition.
