The German Research Center for Artificial Intelligence (DFKI GmbH) is 
seeking for its Language Technology Lab a
in the area of speech signal processing, for a research position 
(Post-Doc, possibly junior) in the DFG project PAVOQUE ("Parametrisation 
of prosody and voice quality for concatenative speech synthesis in view 
of emotion expression").

The aim of PAVOQUE is to overcome the lack of expressivity of current 
unit selection synthesizers by combining the naturalness of corpus-based 
synthesis with the parametrisability of earlier technologies such as 
diphone and formant synthesis. PAVOQUE will carry out basic research on 
methods for the required parametrisation of the key parameters for vocal 
expression of emotion: prosody and voice quality. Two strategies will be 
pursued: parameter-based selection of units from the corpus, and 
post-processing of the synthetic speech signal with signal manipulation 
methods. This aims to provide a high degree of expressivity while 
maintaining good quality of the speech signal.

The responsibilities for the research position include, among others, 
the following:
* Proposal, implementation and assessment of signal analysis algorithms 
for labelling a speech synthesis corpus, particularly with prosodic and 
voice quality features;
* Proposal, implementation and assessment of signal modification 
algorithms for post-processing prosody and voice quality of selected 
units during synthesis;
* Contribution to the realisation of novel unit selection algorithms 
using the annotated features in selection and combining them with signal 

An ideal candidate will have a strong background in speech signal 
processing, some experience with speech synthesis, and clearly 
demonstrable experience with practical development of analysis and 
modification algorithms for speech prosody and voice quality. The 
candidate should be an experienced Java and/or C/C++ programmer. A 
broader interest in issues related to speech synthesis and 
expressive/emotional speech would be highly welcome. Highly valued 
personal qualities include team spirit, creativity, self-motivation, and 
the ability to communicate ideas clearly, combined with a determination 
to meet project goals

Ideally the applicant would have a completed PhD degree.

The earliest starting date of the position is May 2006. The initial 
duration of the contract will be two years, with a possibility for
