Real-Time Speech Processing Algorithms for Smartphone Based Hearing Aid Applications
(2021-04-26)
Signal processing algorithms are extensively used in hearing aid applications to improve the
quality and intelligibility of speech. The hearing aid device (HAD) signal processing pipeline
consists of several key modules ...
Development and Analysis of Real-Time Acoustic Feedback Cancellation and a Clinical Testing Simulator for Hearing Studies
(2018-07-18)
Acoustic feedback stems from acoustic coupling between the loudspeaker and microphone in
hearing systems. Unpleasant outcomes of acoustic feedback, such as howling and whistling
sounds, are major complaints of people ...
Real-Time Smartphone Apps Integrating Signal Processing Modules of Hearing Aids
(2018-05)
This thesis covers the integration of several signal processing modules that appear in digital
hearing aids as real-time smartphone apps. The modules that are considered for integration in the
developed apps in this ...
Guidelines and Benchmarks for Deployment of Deep Learning Models on Smartphones as Real-Time Apps
(2019-05)
In many pattern recognition or machine learning applications, deep learning models or deep neural
networks have provided superior performance relative to feature-based classifiers. Although there
exist a number of publicly ...
Smartphone-Based Single and Dual Microphone Speech Enhancement Algorithms for Hearing Study
(2018-05)
Speech Enhancement (SE) is elemental in many real world applications. In the last two decades,
extensive studies have been carried out on single and multi-channel SE techniques. In this thesis,

Noise-Robust Speech Source Localization and Tracking Using Microphone Arrays for Smartphone-Assisted Hearing Aid Devices
(2018-05)
Speech Source Localization (SSL) (or Direction of Arrival estimation) is a powerful pre-processing tool that helps identify the direction of the talker of interest in a noisy environment using multiple fixed microphones ...
Dual Microphone Speech Enhancement Algorithms on Android-Based Devices for Hearing Study
(2018-08)
Speech Enhancement (SE) is a key module in the Hearing Aid (HA) signal processing pipeline
and improves the listening comfort. Over the last few decades, researchers have developed many
single and dual-microphone SE ...
Multi-Channel Dynamic-Range Compression Techniques for Hearing Devices
(2018-08)
Dynamic-range compression (DRC) is an important component in hearing aid devices (HADs).
Research of multi-channel DRC design and real-time implementation has been carried out in the
last few decades. The trade-offs of ...
Real-Time Simulink Implementation of Noise Adaptive Speech Processing Pipeline of Cochlear Implants
(2017-05)
This thesis presents a real-time Simulink implementation of a noise adaptive speech processing pipeline for cochlear implants that was developed in a previous work. After providing an overview of each component or module ...
