Czech triphone synthesis of female voice
Horák, Petr ; Hesounová, Alžběta
The new triphone inventory of a female voice for TTS system has been finished. The motivation for its creation was the fact that there was no female voice synthesis for Czech that would be at our disposal, although it is needed in various applications. The corpus of the texts used for labelling of the new inventory consisted of 550 sentences. The texts were read by a professional female speaker who was instructed to pronounce the sentences with ideally a monotonous prosody, at a constant speech rate.

Automatic speech segmentation using Czech TTS
Horák, Petr
This paper presents automatic phonetic segmentation of natural speech based on the use of a speech synthesizer and dynamic time warping (DTW) algorithm. A speech synthesizer is used to create a synthetic reference speech pattern with phonetic segmentation information (phonemes, diphones, syllables, intonation units etc.). The reference synthetic speech pattern is then used in the alignment process. The segmentation system has been developed for Czech and it uses the Czech TTS system.
