Recording and Annotation of Speech Corpus for Czech Unit Selection Speech Synthesis

Abstract

The paper gives a brief summarisation of preparation and recording of a phonetically and prosodically rich speech corpus for Czech unit selection text-to-speech synthesis. Special attention is paid to the process of two-phase orthographic annotations of recorded sentences with regard to their coherence.

Towards automatic audio track generation for Czech TV broadcasting: Initial experiments with subtitles-to-speech synthesis

“…The male voice has been already built following the methodology described in [5]. The TTS system running a MUI version with this voice will be referred as MM henceforth.…”

Prosodic Phrases and Semantic Accents in Speech Corpus for Czech TTS Synthesis

“…We have used our speech corpus [7] designed as the source dataset for our text-to-speech system ARTIC. A test layout description and technical issues together with information about the source corpus and test participants are in [6].…”

Several Aspects of Machine-Driven Phrasing in Text-to-Speech Systems

“…For our experiments, we have used the corpus of 9,596 Czech declarative sentences recorded by a male speaker and used in the Czech TTS system ARTIC (Matoušek and Romportl, 2007). Prosodic phrases were automatically annotated in the whole corpus by a method based on artificial neural networks (Romportl, 2010b) trained on 250 manually inter-subjectively annotated sentences (Romportl, 2010a).…”
