Pronunciation dictionaries are the interface between ortho-graphic and phonetic representation of the speech signal and are thereby a substantial component of speech recognition systems. In many systems simple canonical pronunciation forms are used within the dictionary. They represent the " correct " pronunciation as they are found in lexicons and neither(More)
This paper presents: a multi-level concept to generate the speech rhythm in the Dresden TTS system for German (DreSS). The rhythm control includes the phrase, the syllabic and the phonemic level. The concept allows the alternative use of rule-based or statistical, but also data driven methods on these levels. To create the rules and to train a neural(More)
In this paper we investigate measures for the evaluation of pronunciation dictionaries that can be used independently of the type of lexicon, the language, a specific recognizer and how the dictionary was generated. We will describe statistical measures, measures based on information theory and performance measures and give examples how these measures can(More)
With the progress of speech synthesis towards the development of complete TTS systems, the databases of speech synthesizers obtain more and more similarity with databases of speech recognizers. This offers new possibilities in combining systems for speech synthesis and recognition. In a new project, we are developing a speech dialogue system with the(More)
