ABSTRACT
Accurate labeling and segmentation of the unit inventory
database is of vital importance to the quality of unit selec-
tion text-to-speech synthesis. Misalignments and mismatch
between the predicted and pronounced unit sequences re-
quire manual correction to achieve natural sounding syn-
thesis. In this paper we have used a log likelihood ra-
tio based utterance verification to automatically detect
annotation errors in a Norwegian two-speaker synthesis
database. Each sentence is assigned a confidence score
