摘要：This Paper concerns the process of embedding an emotion in the speech using Time Domain Pitch Synchronization Overlap and Add. The goal was to modify the pitch of the speech that can portray emotion with different levels of intensity. To achieve this, the system was based on theoretic frameworks developed by Psychologists to describe emotions. The basic goal is to perform synthesize the speech so that it sounds naturally. To increase the naturalness of the synthesized speech, the synthesized speech should deliver certain content in right emotion (e.g. good news are delivered in a happy voice), therefore making the speech and content more believable. Embedding emotion to the speech is a step in this direction. Embedding emotion seems to be straightforward initially but revealing the emotions adds more difficulties in studying and implementation.
