Abstract

While unit selection speech synthesis tries to avoid speech modifications, it strongly depends on the placement of units into the correct position. Usually, the position is tightly coupled with a distance from the beginning/end of some prosodic or rhythmic units like phrases or words. The present paper shows, however, that it is not necessary to follow position requirements, when the phonetic knowledge of the perception of prosodic patterns (mostly durational in our case) is considered. In particular, we focus on the effects of using word-final units in word-internal positions in synthesized speech, which are often perceived negatively by listeners, due to disruptions in local timing.
