Abstract: This paper proposes a method to parameterize power envelopes in order to modify the power envelope of neutral speech to convert into emotional speech. Target prediction model that can predict the stable power target in short-term interval is firstly used to estimate the targets of the power envelope. Then we change the targets to a stepwise function by segmenting the starting and ending points in each period. By controling the stepwise targets of the power envelope, a power envelope for emotional speech can be reproduced by 2nd-order critically damped model. Results show that this method show excellent performance for parameterizing power envelopes.
