Digital music has become prolific in the web in recent decades. Automated recommendation systems are essential for users to discover music they love and for artists to reach appropriate audience. When manual annotations and user preference data is lacking (e.g. for new artists) these systems must rely on content based methods. Besides powerful machine(More)
Emotional content is a major component in music. It has long been a research topic of interest to discover the acoustic patterns in the music that carry that emotional information , and enable performers to communicate emotional messages to listeners. Previous works looked in the audio signal for local cues, most of which assume monophonic music, and their(More)
We propose the multivariate autoregressive model for content based music auto-tagging. At the song level our approach leverages the multivariate autoregressive mixture (ARM) model, a generative time-series model for audio, which assumes each feature vector in an audio fragment is a linear function of previous feature vectors. To tackle tag-model estimation,(More)
We developed automatic computational tools for the monitoring of pathological mental states – including characterization, detection, and classification. We show that simple temporal domain features of speech may be used to correctly classify up to 80% of the speakers in a two-way classification task. We further show that some features strongly correlate(More)
—We demonstrate usage of smartphones and smartwatches to automatically recognize a person's behavioral context in-the-wild. In our setup, subjects use their own personal phones and engage in regular behavior in their natural environments. Our system fuses complementary information from multi-modal sensors and simultaneously recognizes many contextual(More)
Foreword The present volume presents the proceedings of the third ISCA Every two years, we gather in Athens to discuss current issues in and methodological approaches to research in linguistics. Our main interest is the development of theory based on experimental evidence as well as the unification of different aspects of linguistics research. Phonetics, as(More)
