Abstrakt¶

ARTIC (Artificial Talker in Czech) is a corpus-based text-to-speech (TTS) system that enables to synthesize an arbitrary text, mainly for the Czech language. Basically, two versions of ARTIC are available - a single unit instance system (also known as fixed-inventory synthesis, e.g. diphone-based synthesis) with the quality of resulting speech limited by the fixed inventory, and multiple unit instance system with the quality profiting from employing a unit selection algorithm to select the longest suitable sequence of phonetic units from many units available. In this paper, a process of building a new Slovak voice for the unit selection version of ARTIC is presented. All steps in the design, from the preparation of a suitable speech corpus to the creation of an acoustic unit inventory of the new Slovak voice and its use in the ARTIC system will be described. Special focus will be given to the description of both phonetic features of Slovak and issues in real-time text processing.
