This article explores the potential of the harmonics plus noise model of speech in the
development of a high-quality vocoder applicable in statistical frameworks, particularly in …

Today speech processing is one of the demanding applications among all others. This
article highlights two important aspects of speech processing, namely which feature …

This paper presents an experimental comparison of a broad range of the leading vocoder
types which have been previously described. We use a reference implementation of each of …

Voice models often use frequency limits to split the speech spectrum into two or more
voiced/unvoiced frequency bands. However, from the voice production, the amplitude …

This thesis aimed at conducting research on the synthesis and expressive transformations of
the singing voice, towards the development of a high-quality synthesizer that can generate a …

Dealing with time series with missing values, including those afflicted by low quality or over-
saturation, presents a significant signal processing challenge. The task of recovering these …

This paper applies a dynamic sinusoidal synthesis model to statistical parametric speech
synthesis (HTS). For this, we utilise regularised cepstral coefficients to represent both the …

When speaking devices such as smartphones, tablet-PCs, or GPS systems are used in noisy
outdoor environments, the intelligibility of speech significantly drops. This is even more …

In this paper, a simple method for time-scale modifications of speech based on a recently
suggested model for AM-FM decomposition of speech signals, is presented. This model is …
