Deep neural network models reveal interplay of peripheral coding and stimulus statistics in pitch perception.

Nature communications Dec 14, 2021
Perception is thought to be shaped by the environments for which organisms are optimized. These influences are difficult to test in biological organisms but may be revealed by machine perceptual systems optimized under different conditions. We invest...

Unifying information theory and machine learning in a model of electrode discrimination in cochlear implants.

PloS one Sep 20, 2021
Despite the development and success of cochlear implants over several decades, wide inter-subject variability in speech perception is reported. This suggests that cochlear implant user-dependent factors limit speech perception at the individual level...

An integrated model of pitch perception incorporating place and temporal pitch codes with application to cochlear implant research.

Hearing research Nov 12, 2016
Although the neural mechanisms underlying pitch perception are not yet fully understood, there is general agreement that place and temporal representations of pitch are both used by the auditory system. This paper describes a neural network model of ...

Speaker-dependent multipitch tracking using deep neural networks.

The Journal of the Acoustical Society of America Feb 1, 2017
Multipitch tracking is important for speech and signal processing. However, it is challenging to design an algorithm that achieves accurate pitch estimation and correct speaker assignment at the same time. In this paper, deep neural networks (DNNs) a...
