Disruptive effects in synthetis

Combining phonetic and corpus-based approaches to remedy disruptive effects in synthetic speech

Provider: GAČR (Czech Science Foundation)
Number: GAČR 16-04420S

Duration: 2016-2018

Principal Investigator: Jindřich Matoušek (Faculty of Applied Sciences, West Bohemian University in Pilsen)
Co-Investigator from the Faculty of Arts: Radek Skarnitzl
Other participants from the Faculty of Arts: T. Bořil, J. Volín


The project aims at basic research into speech synthesis. The key idea in the proposed project is to confront phonetic knowledge of the characteristics of natural speech with the characteristics present in synthetic speech and to exploit the acquired know-how to remedy disruptive effects in synthetic speech and to enhance the performance of corpus-based speech-synthesis techniques. Emphasis will be placed on a thorough analysis of contemporary problems perceived in synthetic speech, identification of relevant phonetic parameters crucial for the quality of synthetic speech and the use of such phonetically justified patterns to drive the latest corpus-based speech synthesis techniques. Special attention will be given to automatic prediction of synthesis errors and to the corresponding signal modification/generation.
