Cochlear Implant Electrode Placement and Music Perception.
JAMA Otolaryngol Head Neck Surg
January 2025
Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, Tennessee.
Importance: Cochlear implants enable improvements in speech perception, but music perception outcomes remain variable. Image-guided cochlear implant programming has emerged as a potential programming strategy for increasing the quality of spectral information delivered through the cochlear implant to improve outcomes.
Objectives: To perform 2 experiments, the first of which modeled the variance in music perception scores as a function of electrode positioning factors, and the second of which evaluated image-guided cochlear implant programming as a strategy to improve music perception with a cochlear implant.
Musical pitch and timbre perception in stuttering children.
Int J Pediatr Otorhinolaryngol
January 2025
Department of Audiology, Ankara Medipol University Faculty of Health Sciences, Ankara, Turkey. Electronic address:
Objectives: This study aims to evaluate musical pitch and timbre perception in children who stutter and compare the results with typically developing children.
Methods: A total of 50 participants were included in the study, consisting of 25 children with stuttering (mean age = 10.06 years; range 6-17 years) and 25 typically developing children (mean age = 10.
Robust text-dependent speaker verification system using gender aware Siamese-Triplet Deep Neural Network.
Network
December 2024
Department of Electronics and Communication Engineering, Dronacharya Group of Institutions, Greater Noida, UP, India.
Speaker verification in text-dependent scenarios is critical for high-security applications but faces challenges such as voice quality variations, linguistic diversity, and gender-related pitch differences, which affect authentication accuracy. This paper introduces a Gender-Aware Siamese-Triplet Network-Deep Neural Network (ST-DNN) architecture to address these challenges. The Gender-Aware Network utilizes Convolutional 2D layers with ReLU activation for initial feature extraction, followed by multi-fusion dense skip connections and batch normalization to integrate features across different depths, enhancing discrimination between male and female speakers.

Acta Otolaryngol
January 2025
Department of Otorhinolaryngology, Lanzhou University Second Hospital, Lanzhou, China.
Background: Cochlear implants (CI) help regain perception of sound for patients with sensorineural hearing loss. The ability to recognize music pitch may be crucial for recognizing and producing speech for Mandarin.
Aims/objectives: This study aims to search for possible influencing factors of music perception and correlations between music perception and auditory speech abilities among prelingually deaf pediatric Mandarin-speaking CI users.
The Relationship of Pitch Discrimination with Segregation of Tonal and Speech Streams for Cochlear Implant Users.
Trends Hear
December 2024
Auditory Research Center, Caruso Department of Otolaryngology - Head and Neck Surgery, Keck School of Medicine, University of Southern California, Los Angeles, California, USA.
Cochlear implant (CI) users often complain about music appreciation and speech recognition in background noise, which depend on segregating sound sources into perceptual streams. The present study examined relationships between frequency and fundamental frequency (F0) discrimination with stream segregation of tonal and speech streams for CI users and peers with no known hearing loss. Frequency and F0 discrimination were measured for 1,000 Hz pure tones and 110 Hz complex tones, respectively.
