| Abstract(in English) | We propose a technique for emotional speech recognition based on multiple-regression HMM (MRHMM). To achieve emotional speech recognition for an arbitrary speaker with a small amount of training data, we incorporate a speaker and style adaptation technique into speaker-dependent MRHMM-based emotional speech recognition. In the proposed technique, we first adapt the speaker-independent model to target speaker's respective styles with a small amount of speech data. Then, using obtained speaker- and style-adapted HMMs and low-dimensional style control vector for each training style, the regression matrices of MRHMM are estimated based on least square method and maximum likelihood estimation. We assess the performance of the proposed technique on the recognition of acted emotional speech uttered by both professional narrators and non-professional speakers and show the effectiveness of the technique. |
