Pitch estimation in diverse naturalistic audio streams remains a challenge for speech
processing and spoken language technology. In this study, we investigate the use of robust …

This study investigates the relationship between the intelligibility and quality of modified
speech in noise and in quiet. Speech signals were processed by seven algorithms designed …

In speech processing, the speech is often considered stationary within segments of 20-30
ms even though it is well known not to be true. In this paper, we take the nonstationarity of …

In this paper, single channel speech enhancement in the time domain is considered. We
address the problem of modelling non-stationary speech by describing the voiced speech …

The single-channel speech enhancement problem is addressed. We propose a pitch-
adaptive short-time Fourier transform (PASTFT) framework to obtain a signal-dependent …

This thesis is concerned with model-based analysis and processing of speech and audio
signals, to which a number of scientific contributions are made in the form of new …

Single-channel speech enhancement refers to the reduction of noise signal components in a
single-channel signal composed of both speech and noise. Spectral speech enhancement …

Cochlear implant (CI) devices are able to help deaf individuals recover hearing ability by
surgically inserting electrode arrays into the inner ear, to stimulate the auditory nerve and …

This project deals with methods for extracting features in signals, which then can be used in
a machine learning approach for recognizing an aircraft in a signal. Noise is often unwanted …
