“…Interestingly, the same pattern of deficit was found in NH participants with vocoded sentences, with a deficit related to the number of vocoded channels, and also a specific deficit for neutrality. This demonstrates efficiently the poor perception of emotional prosody in CI users that has already been documented before [ 28 , 37 , 38 , 110 ], and allows for a better characterization of this deficit depending on the emotion. Moreover, here, the double paradigm using both emotion categorization and intensity ratings allowed us to show that the perception of emotional prosody is not fully disrupted in CI users.…”

In the case of hearing loss, cochlear implants (CI) allow for the restoration of hearing. Despite the advantages of CIs for speech perception, CI users still complain about their poor perception of their auditory environment. Aiming to assess non-verbal auditory perception in CI users, we developed five listening tests. These tests measure pitch change detection, pitch direction identification, pitch short-term memory, auditory stream segregation, and emotional prosody recognition, along with perceived intensity ratings. In order to test the potential benefit of visual cues for pitch processing, the three pitch tests included half of the trials with visual indications to perform the task. We tested 10 normal-hearing (NH) participants with material being presented as original and vocoded sounds, and 10 post-lingually deaf CI users. With the vocoded sounds, the NH participants had reduced scores for the detection of small pitch differences, and reduced emotion recognition and streaming abilities compared to the original sounds. Similarly, the CI users had deficits for small differences in the pitch change detection task and emotion recognition, as well as a decreased streaming capacity. Overall, this assessment allows for the rapid detection of specific patterns of non-verbal auditory perception deficits. The current findings also open new perspectives about how to enhance pitch perception capacities using visual cues.

“…Speech prosody allows a listener to distinguish emotions and intention (e.g., the presence of sarcasm), and to distinguish statements from questions and nouns from verbs (e.g., “ ob ject” from “ob ject ”). CI users typically have impaired speech prosody perception ( Xin et al, 2007 ; Meister et al, 2009 ; Everhardt et al, 2020 ) and report high levels of listening effort ( Alhanbali et al, 2017 ). Access to pitch information has been shown to be critical to perception of speech prosody ( Murray and Arnott, 1993 ; Banse and Scherer, 1996 ; Most and Peled, 2007 ; Xin et al, 2007 ; Peng et al, 2008 ; Meister et al, 2009 ).…”

Cochlear implants (CIs) have been remarkably successful at restoring speech perception for severely to profoundly deaf individuals. Despite their success, several limitations remain, particularly in CI users’ ability to understand speech in noisy environments, locate sound sources, and enjoy music. A new multimodal approach has been proposed that uses haptic stimulation to provide sound information that is poorly transmitted by the implant. This augmenting of the electrical CI signal with haptic stimulation (electro-haptic stimulation; EHS) has been shown to improve speech-in-noise performance and sound localization in CI users. There is also evidence that it could enhance music perception. We review the evidence of EHS enhancement of CI listening and discuss key areas where further research is required. These include understanding the neural basis of EHS enhancement, understanding the effectiveness of EHS across different clinical populations, and the optimization of signal-processing strategies. We also discuss the significant potential for a new generation of haptic neuroprosthetic devices to aid those who cannot access hearing-assistive technology, either because of biomedical or healthcare-access issues. While significant further research and development is required, we conclude that EHS represents a promising new approach that could, in the near future, offer a non-invasive, inexpensive means of substantially improving clinical outcomes for hearing-impaired individuals.

“…Degraded speech also impairs verbal cognitive processes, such as working memory and, in children, acquisition of new words (Newman et al, 2020;Sullivan et al, 2015). Finally, not only does degraded speech impact word recognition and linguistic processing, it may also disrupt acoustic cues related to speech prosody, such as intonation, pitch, and stress, all of which are critical for emotion recognition and processing (Everhardt et al, 2020;Tinnemore et al, 2018).…”

Purpose The purpose of this article is to discuss the impact of COVID-19 mitigation strategies on face-to-face communication. The article covers three main areas: the effect of face masks and social distancing on aspects of communication, including speech production, speech recognition, and emotion recognition; the effect of face masks on access to visual speech cues; and downstream effects of poor speech recognition on language and cognitive abilities. Conclusions The use of face masks and social distancing are proven mitigation strategies to minimize the spread of COVID-19 and other airborne diseases. However, these strategies may place individuals with hearing, speech, and language disorders at greater risk for communication problems in their daily lives. Practitioners who work directly with these patients should consider these issues when discussing communication strategies with their patients.
