Fundamental frequency is one of the most important characteristics of speech and audio
signals. Harmonic model-based fundamental frequency estimators offer a higher estimation …

Due to their high temporal resolution and large dynamic range event cameras are uniquely
suited for the analysis of time-periodic signals in an image. In this work we present an …

This paper shows that time varying pitch properties can be used advantageously within the
segmentation step of a multi-talker diarization system. First a study is conducted to verify that …

In some situations, speech can be a disturbing source of ambient noise. Active noise control
(ANC) systems have difficulties in dealing with speech due to its non-stationary nature when …

We present a continuous-time probabilistic approach for estimating the chirp signal and its
instantaneous frequency function when the true forms of these functions are not accessible …

This paper demonstrates how the harmonic structure of voiced speech can be exploited to
segment multiple overlapping speakers in a speaker diarization task. We explore how a …

The identification of nonlinear chirp signals has attracted notable attention in the recent
literature, including estimators such as the variational mode decomposition and the …

Pitch estimation is widely used in speech and audio signal processing. However, the current
methods of modeling harmonic structure used for pitch estimation cannot always match the …

In environments such as open offices, call centres, etc., speech is often the main disturbing
source of ambient noise, reducing concentration and productivity. Active noise control (ANC) …

In designing a frequency tracker, the goal is to follow the continual time variation of the
frequency from a particular sinusoidal component in a noisy signal with a high accuracy and …
