![]() ![]() This “musician effect” has not been consistently observed across studies ( Ruggles et al., 2014) and may depend on the listening task ( Fuller et al., 2014). Long-term musical experience has been shown to improve both speech and music perception ( Peretz et al., 2003 Kraus et al., 2009 Parbery-Clark et al., 2009), possibly because musicians are able to extract and track pitch in complex listening environments. ![]() Such data are important for future comparison to performance in hearing-impaired listeners (e.g., HA users, CI users, bimodal listeners, etc.). In this paper, we present speech and music perception results with the SSC in adult normal hearing (NH) listeners. The size of the database (100 000 possible sentences with 27 possible contours) makes the SSC useful to compare performance across numerous experimental conditions. The SSC may be especially useful for evaluating speech and music perception in unilateral and bilateral CI users, bimodal listeners, and normal hearing (NH) listeners with pitch processing deficits. Thus, the SSC may help elucidate the contributions of pitch and timbre to speech and music perception. The SSC allows sentence recognition to be measured with or without variations in pitch cues (fundamental frequency or F0) and melodic pitch perception to be measured with and without variation in words or timbre cues, both using the same stimuli. To address these concerns, we have created a database of sung monosyllable words that contain both musical pitch and speech information called the Sung Speech Corpus (SSC). This may allow better observation of the contributions and interactions between acoustic and electric hearing. It seems preferable to combine varying musical pitch and speech information within a stimulus such that both devices will be needed to perform the task. As such, a subject is likely to focus on a single device during a particular task because that cue is better represented by a single device making it difficult to observe a bimodal benefit. The results indicate that CIs convey speech information quite well, and the HAs convey the pitch information quite well. In previous bimodal studies, very different stimuli (e.g., speech versus piano notes) and perceptual tests (e.g., speech understanding in noise versus melodic contour identification) have been used to evaluate bimodal performance. ![]() The benefits of bimodal listening are somewhat variable, often with listeners attending to the “better ear” for different speech and music perception tasks (e.g., Crew et al., 2015). For cochlear implant (CI) users with residual acoustic hearing, combined use of the CI and a hearing aid (HA) in the contralateral ear has been shown to improve speech and music perception ( Kong et al., 2005 Dorman et al., 2008 Crew et al., 2015). ![]()
