This paper describes the acquisition of a new database of dysarthric speech in terms of
aligned acoustics and articulatory data. This database currently includes data from seven …

During the past three decades, the issue of processing spectral phase has been largely
neglected in speech applications. There is no doubt that the interest of speech processing …

In many speech processing applications, the spectral amplitude is the dominant information
while the use of phase spectrum is not so widely spread. In this paper, we present an …

Adaptive filters (AFs) are vital for enhancing the performance of downstream tasks, such as
speech recognition, sound event detection, and keyword spotting. However, traditional AF …

In this paper we describe two families of algorithms for hands-free speech recognition using
microphone arrays. Enhancement-based approaches use a cascade of independent …

In this paper we propose a new method for utilising phase information by complementing it
with traditional magnitude-only spectral subtraction speech enhancement through complex …

(57) ABSTRACT A microphone-array-based speech recognition system com bines a noise
cancelling technique for cancelling noise of input speech signals from an array of …

In issues like hearing impairment, speech therapy and hearing aids play a major role in
reducing the impairment. Removal of noise signals from speech signals is a key task in …

This paper studies the statistical properties of the gain functions, which are often used for
two-channel post-filtering (TC-PF) algorithms. We reveal that the smoothing factor has a …

In this paper, the design of a FPGA-based rapid prototype for Short-Time Fourier Transform
(STFT) based spectral subtraction for hands-free speech applications using Xilinx System …
