Abstract:

Conventional features have achieved good performance in speech emotion recognition. However, these features are based on short-time analysis without considering the non-stationary properties. In this paper we focus on wavelet packet techniques, which can provide an improved signal representation with a tradeoff between time and frequency ...More
