Abstract
The paper is on the proposal of a novel approach to modeling prosodic features. Our model is based on the idea of introducing subspace of model parameters.
Annotation
We propose a novel approach to modeling prosodic features. Inspired by Joint Factor Analysis model (JFA), our model is based on the same idea of introducing subspace of model parameters. However, the underlying Gaussian Mixture distribution of JFA is replaced by multinomial distribution to model sequences of discrete units rather than continuous features. In this work, we use the subspace model as a feature extractor for support vector machines (SVMs), similar to the recently proposed JFA in total variability space. We can show the capability to reduce high-dimensional count vectors to low dimension while keeping system performance stable. With additional intersession compensation, we can improve 30% relative to the baseline system and reach an equal error rate of 8.8% on the NIST 2006 SRE dataset.
