Abstract

To achieve naturalness of speech generated by ARTIC TTS, there is a need to analyze the phenomena causing the deterioration of naturalness. By locating and precisely determining the places which have a disruptive effect, there is a possibility to analyze such phenomena. The analysis of the source of the problems can then establish whether the disruption was caused by the use of a unit in an unsuitable context, by inaccurate segmentation of a unit, by extensive modification of a unit, by spectral discontinuity at the place of concatenation or by any other factor. It is important for the focusing of our further effort on the elimination of the problem by an appropriate method such as unit selection, increase of segmentation accuracy, etc. For the purposes of analysis, we asked several listeners to identify as precisely as possible the places which they did not like in the synthetic speech, and to describe the reason why they did not like them.
