Kernelized Rényi distance for speaker recognition
2010
2010 IEEE International Conference on Acoustics, Speech and Signal Processing
Preserved Fulltext
The proposed entropic distance, the Kernelized Rényi distance (KRD), is formulated in a non-parametric way and the resulting measure is efficiently evaluated in a parallelized fashion on a graphical processor ...
We propose a new information theoretic approach for computation of the matching score using the Rényi entropy. ...
We will refer to this measure as the Kernelized Rényi Distance (KRD) and will use it for calculating matching scores. ...

Information theoretic measures have been used for sampling the data, retaining its original information content. We propose an efficient Rényi entropy based subset selection algorithm. ...
In the second application, our subset selection approach is used to replace vector quantization in a standard object recognition algorithm, and improvements are shown. ...
We derive a distance measure termed the kernelized Rényi distance (KRD) based on the Renyi entropy with α = 2. ...

This confirms the role of noisiness for speech recognition, and will further be extended to the classification of voice quality for the design of an automatic voice casting system in video games. ...
The improvement is around 10% in relative error reduction, and is particularly significant for the recognition of noisy speech -i.e., whispery/breathy speech. ...
In particular, the objective of a voice casting system differs qualitatively from standard speaker recognition applications : in standard speech recognition applications (speaker identification/verification ...

We provide a comprehensive empirical study of four metrics; class separation, kernel quality, Lyapunov's exponent and spectral radius. ...
We find that the two metrics that correlate most strongly with the classification performance are Lyapunov's exponent and kernel quality. ...
