The present paper reports on the DFKI entry to the Blizzard challenge 2008. The main difference of our system compared to last year is a new join model inspired by last year's iFlytek paper; the effect seems small, but measurable in the sense that it leads to the selection of longer chunks of consecutive units. In interpreting the results of the listening(More)
Synthesizing desired emotions using concatenative algorithms relies on collection of large databases. This paper focuses on the development and assessment of a simple algorithm to interpolate the intended vocal effort in existing databases in order to create new databases with intermediate levels of vocal effort. Three diphone databases in German with soft,(More)
In this paper we present two virtual characters in an interactive poker game using RFID-tagged poker cards for the interaction. To support the game creation process, we have combined models, methods, and technology that are currently investigated in the ECA research field in a unique way. A powerful and easy-to-use multimodal dialog author-ing tool is used(More)
A system for classification of audio signals containing speech, music, noise and silence is proposed. Appropriate subband processing is applied for the characterization of each sound source. The algorithm operates in four steps to classify the contents of a given audio signal. The acoustical parameters and statistical measures to be used in the(More)
This paper presents a comparison of methods for transforming voice quality in neutral synthetic speech to match cheerful, aggressive, and depressed expressive styles. Neutral speech is generated using the unit selection system in the MARY TTS platform and a large neutral database in German. The output is modified using voice conversion techniques to match(More)
iii ACKNOWLEDGEMENTS I would like to thank to my thesis supervisor Assoc. Prof. Levent M. Arslan for his guidance and support. It was a great pleasure to work with him during this thesis and in all the projects we have been involved in the last three years. I would like to thank Prof. reading my thesis and participating in my thesis committee. I would like(More)
The paper describes the Blizzard Challenge 2009 participation of MARY TTS, an open-source TTS system using a unit selection voice. We briefly outline the new language support framework we provide so that people can add support for their languages to MARY TTS, and describe how that framework was used for building a Mandarin Chinese system and voice.
