Emotional Text to Speech Synthesis: A Review

Emotional speech synthesis: a review

Attempts to add emotion effects to synthesised speech have existed for more than a decade now. Several prototypes and fully operational systems have been built based on different synthesis techniques, and quite a number of smaller studies have been conducted. This paper aims to give an overview of what has been done in this field, pointing out the inherent properties of the various synthesis te...

Two-stage prosody prediction for emotional text-to-speech synthesis

In this paper, we adopt a difference approach to prosody prediction for emotional text-to-speech synthesis, where the prosodic variations between emotional and neutral speech are decomposed into the global and local prosodic variations and predicted using a two-stage model. The global prosodic variations are modeled by the means and standard deviations of the prosodic parameters, while the loca...

Emotional Analysis for Malayalam Text to Speech Synthesis Systems

The inclusion of emotional aspects into speech can improve the naturalness of speech synthesis system. The different emotions sadness, angry, happiness are manifested in speech as prosodic elements like time duration, pitch and intensity. The prosodic values corresponding to different emotions are analyzed at word as well as phonemic level, using speech analysis and manipulation tool PRAAT. Thi...

Voice quality interpolation for emotional text-to-speech synthesis

Synthesizing desired emotions using concatenative algorithms relies on collection of large databases. This paper focuses on the development and assessment of a simple algorithm to interpolate the intended vocal effort in existing databases in order to create new databases with intermediate levels of vocal effort. Three diphone databases in German with soft, modal, and loud voice qualities are p...
