Cochlear implants users report great difficulty in pitch perception. This problem is acute among implantees in tone language environments, and especially in children. This thesis addresses the development of perceptual training methods for children in tone language environments with cochlear implants via 5 experiments, each providing insight into the best methods for solving this problem.

Cochlear implants are currently the standard treatment for profound sensorineural hearing loss. In the last decade, advances in auditory science and technology have not only greatly expanded the utility of electric stimulation to other parts of the auditory nervous system in addition to the cochlea, but have also demonstrated drastic changes in the brain in responses to electric stimulation, including changes in language development and music perception. Volume 20 of SHAR focused on basic science and technology underlying the cochlear implant. However, due to the newness of the ideas and technology, the volume did not cover any emerging applications such as bilateral cochlear implants, combined acoustic-electric stimulation, and other types of auditory prostheses, nor did it review brain plasticity in responses to electric stimulation and its perceptual and language consequences. This proposed volume takes off from Volume 20, and expands the examination of implants into new and highly exciting areas. This edited book starts with an overview and introduction by Dr. Fan-Gang Zeng. Chapters 2-9 cover technological development and the advances in treating the full spectrum of ear disorders in the last ten years. Chapters 10-15 discuss brain responses to electric stimulation and their perceptual impact. This volume is particularly exciting because there have been quantum leap from the traditional technology discussed in Volume 20. Thus, this volume is timely and will be of real importance to the SHAR audience.

The cochlear implant is a device that bypasses a nonfunctional inner ear and stimulates the auditory nerve directly. Written by the "father" of the multi-electrode implant, this comprehensive text and reference gives an account of the principles underlying cochlear implants and their clinical application. For the clinician, the book will provide guidance in the treatment of patients; for the engineer and researcher it will provide the background for further research; and for the student, it will provide a through understanding of the subject.

Emotional prosody, which refers to the process of expressing emotions through spoken language, is essential for correctly recognizing speakers' emotional states during spoken communication. Previous research has shown that non-tonal language-speaking individuals with cochlear implants (CIs) demonstrate deficits in perceiving and producing emotional prosody, as compared to their typical hearing (TH) counterparts. These research, however, did not explore how well tonal language-speaking individuals (e.g., Mandarin) with CIs perceive and produce emotional prosody in speech, in comparison to their TH counterparts. Additionally, no data are available to clarify whether CI adults who speak tonal languages differ from those who speak non-tonal languages with respect to the extent of emotional prosodic processing. These concerns were addressed in this dissertation through four experiments. The first experiment explores the differences in emotional prosody perception between 15 TH adults and 15 CI adults. All were native Mandarin-speaking adults. The TH listeners were required to listen to natural speech stimuli and noise-vocoded speech stimuli designed to stimulate CI input. The CI adults were only asked to listen to natural speech. The results showed that overall emotional prosody recognition by TH and CI listeners for natural speech is 72.8% and 50.3%, respectively. These findings suggest that CI adults demonstrate deficits in perceiving emotional prosody. TH listeners performed better with natural speech than with noise-vocoded speech, and their intelligibility was lower when the number of noisevocoded filter channels was reduced. In addition, the performance of CI listeners in natural speech was similar to that of TH listeners at a lower channel setting (at 4-channel), in contrast to 8-channel shown in previous comparable studies of non-tonal languages (e.g., English). This finding provide evidence consistent with a "functional view" hypothesis, which claims that Mandarin (a tonal language that uses pitch for purposes of linguistic tone) has relatively little prosodic space to signal emotional prosody through the pitch dimension. The second experiment was intended to determine whether enhancement of secondary cues (duration and amplitude) can benefit CI listeners to perceive emotions. This was explored by modifying the prosodic cues for two contrasting emotions, "happy" and "sad", and observing how the CI listeners perceived these modifications. The result showed that increased duration cues can slightly improve recognition of the "sad" emotion and increased amplitude can improve identification of the "happy" emotion. These findings suggest that the selected enhancement of secondary cues could potentially benefit CI listeners. The third experiment investigated whether TH and CI talkers differ in terms of acoustic cue production and examined which acoustic measures are most predictive of emotions produced by these talkers. This was done by analyzing the fundamental frequency (F0), intensity, and duration patterns of short sentences spoken by the TH and CI talkers in the "angry", "happy" and "sad" emotional contexts. The results suggested that CI talkers showed decreased mean intensity, increased intensity range, and sentence duration values in their emotional prosody productions compared to their TH counterparts. In addition, a machine learning (decision tree) model of emotion classification was used to analyze which acoustic measures were most predictive of three emotions produced by TH and CI talkers. The results indicated that TH talkers utilize intensity as the most important classifier, followed by F0 to predict the three emotions, while CI talkers used duration as the most important classifier, followed by intensity. The findings of model indicated that the secondary cues (duration and intensity) are most predictive in classifying the three emotions in the CI talkers' productions. The fourth experiment examined the production data in a perceptual manner to determine whether the deficits of CI talkers described acoustically in Experiment 3 could be perceived by TH listeners. The results confirm that CI users show impaired emotional prosody production, and this deficit is reflected in lowered perception scores by TH listeners. In addition, CI talkers received more judgments for the "neutral" emotion than did TH talkers, even though these produced sentences were not intended to express a "neutral" emotion. This pattern of result suggests that the CI users produced speech with impaired F0, resulting in a less perceptible (and therefore more monotone or "neutral") judgement. Finally, there was a significant correlation (r=0.524, p

Introduction On behalf of the Organizing Committee of the Third Congress of Asia Pacific Symposium on Cochlear Implant and Related Sciences (3rd APSCI), I would like to extend my heartfelt thanks to all the attendants at the meeting, as well as to the contributors to these Proceedings. As most of you will have realized, the meeting was a great success both from a scientific as well as a social point of view. Almost four hundred attendants from 25 countries gathered in the Osaka Convention Hall. The program consisted of three parallel workshops spanning one and a half days, and three full days of scientific sessions. The weather was ideal, and our guests were able to see the cherry trees in full blossom and to enjoy their fill of Japanese culture. We have great pleasure in sending you your copy of the Proceedings of the 3rd APSCI, which contains all the updated information and state-of-the-art knowledge on cochlear implants and implantable hearing devices. As is indicated in the title of the meeting, this book covers many areas that are of scientific interest to us. The articles cover subjects ranging from surgical issues with regard to cochlear implantation, to basic studies on the auditory system, developmental studies in children, communication skills, speech, and education, etc. In addition, the reader will observe that some of the articles are related to implantable middle ear devices, a subject which was not covered in the proceedings of the 1st and 2nd APSCI meetings. The editors sincerely hope that this book will contribute to the development of cochlear implants and middle ear devices. Takeshi Kubo, MD President, 3rd APSCI

For many years or decades, cochlear implants have been an exciting research area covering multiple disciplines which include surgery, engineering, audiology, speech language pathology, education and psychology, among others. Through these research studies, we have started to learn or have better understanding on various aspects of cochlear implant surgery and what follows after the surgery, the implant technology and other related aspects of cochlear implantation. Some are much better than the others but nevertheless, many are yet to be learnt. This book is intended to fill up some gaps in cochlear implant research studies. The compilation of the studies cover a fairly wide range of topics including surgical issues, some basic auditory research, and work to improve the speech or sound processing strategies, some ethical issues in language development and cochlear implantation in cases with auditory neuropathy spectrum disorder. The book is meant for postgraduate students, researchers and clinicians in the field to get some updates in their respective areas.
