Laughter detection using ALISP-based N-Gram models
Résumé
Laughter is a very complex behavior that communicates a wide range of messages with different meanings. It is highly
dependent on social and interpersonal attributes. Most of the previous works (e.g. [1, 2]) on automatic laughter
detection from audio uses frame-level acoustic features as parameters to train their machine learning techniques, such as
Gaussian Mixture Models (GMMs), Support Vector Machines (SVMs) etc. However, segmental approaches that capture
higher-level events have not been adequately focussed due to the nonlinguistic nature of laughter. This paper is an
attempt to detect laughter regions with the help of automatically acquired acoustic segments using Automatic Language
Independent Speech Processing (ALISP) [3, 4] models.
