Introduction: Hearing impairment (AD) can harm the subject in several contexts, which often generates negative feelings and difficulties in communication. To mitigate the commitments generated by AD, there are compensatory conducts, among them, the Cochlear Implant (CI). Although this device contributes to hearing improvement, many users still have several complaints of speech recognition in a noisy situation (competitive speech). Thus, factors other than audibility, can act in this recognition, among them the temporal ability. Objective: To verify if there is a correlation between the performance of temporal processing and the recognition of competitive and / or distorted speech in patients using Cochlear Implants. Method: Participants underwent the following assessments: anamnesis, free field audiometry with Cochlear Implant at 250 to 4000Hz sound frequencies, TPF - “Frequency Pattern Test”, TPD - “Duration Pattern Test”, SSI - Test of Sentencing Identification with Competitive Message (Synthetic Sentences Identification in Portuguese) and LSP - "List of Sentences in Portuguese" in the noise condition. The data were analyzed using the Pearson and Spearman coefficient, the Shapiro-Wilk test, the Mann-Whitney U test, the Student t test and two-dimensional scatter plots. In addition, a descriptive analysis of the data was performed using the SPSS Statistics software, version 25.0. Hypothesis: CI users with greater difficulty in temporal ability are those who have the worst performance in competitive speech. Results: There was a statistically significant relationship between the tests that assess temporal ability - SSI and TPF (appointment) - and the test that evaluates competitive speech recognition - LSP. Conclusion: CI users who performed well in the test with competitive speech in the noise condition (LSP) obtained equivalent results in the SSI tests (signal-to-noise ratio +10, 0, -10), and TPF - appointment, which assess the ability of deep figure and temporal ability, respectively.
