A Simple Continuous Pitch Estimation Algorithm

Petr Motlicek, Philip Neil Garner, Milos Cernak

Recent work in text to speech synthesis has pointed to the benefit of using a continuous pitch estimate; that is, one that records pitch even when voicing is not present. Such an approach typically requires interpolation. The purpose of this paper is to sh ...

Transcribing meetings with the AMIDA systems

John David Scott Dines, Philip Neil Garner

In this paper we give an overview of the AMIDA systems for transcription of conference and lecture room meetings. The systems were developed for participation in the Rich Transcription evaluations conducted by the National Institute for Standards and Techn ...

Vocal Tract Length Normalization for Statistical Parametric Speech Synthesis

Lakshmi Babu Saheer, John David Scott Dines, Philip Neil Garner

Vocal tract length normalization (VTLN) has been successfully used in automatic speech recognition for improved performance. The same technique can be implemented in statistical parametric speech synthesis for rapid speaker adaptation during synthesis. Thi ...

Cepstral normalisation and the signal to noise ratio spectrum in automatic speech recognition

Philip Neil Garner

Cepstral normalisation in automatic speech recognition is investigated in the context of robustness to additive noise. In this paper, it is argued that such normalisation leads naturally to a speech feature based on signal to noise ratio rather than absolu ...

Beamforming with a Maximum Negentropy Criterion

Weifeng Li, Philip Neil Garner

In this paper, we address a beamforming application based on the capture of far-field speech data from a single speaker in a real meeting room. After the position of the speaker is estimated by a speaker tracking system, we construct a subband-domain beamf ...
