Adaptive Filters A Tutorial for the Course Computational Intelligence (2009)
Christian Feldbauer, Franz Pernkopf, Erhard Rank
This tutorial introduces the LMS (least mean squares) and the RLS (recursive least-squares) algorithm for the design of adaptive transversal filters. These algorithms are applied for identification...
Automatic Speech Recognition with HTK A Tutorial for the Course Computational Intelligence (2009)
This tutorial introduces the main components for an automatic speech recognition system. The acoustic information is sampled as a signal suitable for processing by computers (a digital signal) and...
Stefan Petrik, Betreuer Dipl. -ing, Erhard Rank
The Wizard of Oz simulation technique is an approved aid for designing speech dialogue systems. There are a number of tools for simulation which have been used successfully, but which are inflexible...
Towards an Oscillator-plus-Noise Model for Speech Synthesis (2008)
The autonomous oscillator model for speech synthesis is augmented by a nonlinear predictor to regenerate the modulated noiselike signal component of speech signals. The resulting...
Generating Intonation Contours Using Tonal Specifications (2007)
Hannes Pirker, Erhard Rank, Harald Trost
. We present a novel approach to intonation modelling for speech synthesis based on a two-layer technique. The generator component of a concept-to-speech system produces an abstract phonological...
Combining Non-uniform Unit Selection with Diphone Based Synthesis”, Eurospeech 2003 (2003)
Michael Pucher, Friedrich Neubarth, Erhard Rank, Georg Niklfeld, Qi Guan
This paper describes the unit selection algorithm of a speech synthesis system, which selects the k-best paths over units from a relational unit database. The algorithm uses words and diphones as...
Accentuation and emotions - Two different systems (2000)
Kai Alter, Erhard Rank, Sonja A. Kotz, Ulrike Toepel, Mireille Besson, Annett Schirmer, ...
Current investigations point to a relationship between syntax and prosody. However, prosody can also be linked to emotional markers of an utterance. We tested the later option with event-related...
On the relations of semantic and acoustic properties of emotions (1999)
Kai Alter, Erhard Rank, Sonja A. Kotz, Erdmut Pfeifer, Mireille Besson, Angela D. Friederici, ...
In the present study, the relation between the semantic content and different acoustic parameters of emotional speech are analyzed. The analyzed corpus includes happiness, neutral state, and anger...

A System of Stylized Intonation Contours in German (1998)
Hannes Pirker, Kai Alter, Erhard Rank, John Matiasek, Harald TROST, Gernot Kubin
Modeling intonation, i.e., specifying adequate fundamental frequency (F0) contours, remains a challenging task for speech synthesis systems. This paper discusses the development of a system for...
Generating Emotional Speech With A Concatenative Synthesizer (1998)
We describe the attempt to synthesize emotional speech with a concatenative speech synthesizer using a parameter space covering not only f0, duration and amplitude, but also voice quality parameters,...
VieCtoS - Speech Synthesizer, Technical Overview (1998)
Erhard Rank, Hannes Pirker, Erhard Rank/hannes Pirker
This report describes the overall architecture of the speech synthesis module developed for VieCtoS, the Vienna concept-to-speech system for Austrian German. A technical description of the methods...
A Waveguide Model for Slapbass Synthesis (1997)
Starting from the waveguide model for plucked strings, a new digital signal processing model for the slapping technique on electric bassguitars is derived. The model includes amplitude limitations...
