Experimental Investigation of Acoustic Features to Optimize Intelligibility in Cochlear Implants

Sensors, 2023
Although cochlear implants work well for people with hearing impairment in quiet conditions, it is well-known that they are not as effective in noisy environments.

Speech Recognition and Acoustic Features in Combined Electric and Acoustic Stimulation [PDF]

Journal of Speech, Language, and Hearing Research, 2012
Purpose In this study, the authors aimed to identify speech information processed by a hearing aid (HA) that is additive to information processed by a cochlear implant (CI) as a function of signal-to-noise ratio (SNR). Method Speech recognition was measured with CI alone, HA alone ...

Research on multi-scenario adaptive acoustic encoders based on neural architecture search

Frontiers in Physics
This paper presents the Scene Adaptive Acoustic Encoder (SAAE) method, which is tailored to diverse acoustic environments for adaptive design. Hand-crafted acoustic encoders often struggle to adapt to varying acoustic conditions, resulting in performance

Open-Environment Robotic Acoustic Perception for Object Recognition

Frontiers in Neurorobotics, 2019
Object recognition in containers is extremely difficult for robots. Dynamic audio signals are more responsive to an object's internal property. Therefore, we adopt the dynamic contact method to collect acoustic signals in the container and recognize ...

Blocking Opioid Receptors in a Songbird Cortical Region Modulates the Acoustic Features and Levels of Female-Directed Singing

Frontiers in Neuroscience, 2020
The organization of the anterior forebrain pathway (AFP) of songbirds important for context-dependent singing is similar to that of cortical basal ganglia loops (CBG) in mammals, which underlie motor behaviors including vocalization.
