    Automatic Prosodic Events Detection Using a Two-Stage SVM/CRF Sequence Classifier with Acoustic Features

    To benefit from the maximum-margin nature of SVMs and also from the ability of CRFs to model correlations between neighboring features, this paper utilizes a two-stage SVM/CRF sequence classifier to detect pro...

    Latent Topic Model Based on Gaussian-LDA for Audio Retrieval

    In this paper,we introduce a new topic model named Gaussian-LDA, which is more suitable to model continuous data. Topic Model based on latent Dirichlet allocation (LDA) is widely used for the statistical analy...

    Speech Fragment Decoding Techniques Using Silent Pause Detection

    Silent pause frequently occurs in spontaneous speech. When recognizing spontaneous speech, silent pause tends to degrade the performance of typical speech recognizers. This paper proposes a fragment decoding m...

    Monaural Voiced Speech Separation with Multipitch Tracking

    Separating voiced speech from its mixtures with interferences in monaural condition is not only an important but also challenging task. As multipitch tracking can enable much better performance of speech separ...
