This area deals with acoustic, physiological, psychoacoustic and computational aspects of phonetics and linguistics.
The acoustic source of voiced speech sounds is located at the vocal folds (glottis). During phonation a quite complex interaction between the control of the subglottal air pressure and the muscles of the glottis takes place. The periodic opening and closing of the vocal folds produces air pressure pulses generating a harmonic source spectrum with decaying amplitudes of the partials from the fundamental frequency by -12dB/octave. The acoustic radiating characteristic at the lip opening provides a gain of +6 dB/octave that the net decay of the amplitude spectrum results at -6dB.
The pharynx and and the oral cavity act as adjustable resonance volumes shaping the glottal source spectrum to the known vowel sounds (timbre). In case of the lowered velum the nasal cavity is coupled to the vocal tract influencing the spectrum of voiced sounds.
Individual and social life finds its expression in speech. Even subtle, prosodic and segment differences in speech are perceived. The monophthongisation of dipthongs (/aE/ und /aO/) is the result of a century's progressive change. The development of the monophthongisation is both individually and regionally specific. The first fomant graph (F1, F2) shows two Viennese speakers, black dipthongs (D) and red monopthongs (M). The second format graph shows 2 Lower Styrian speakers (black dipthongs (D) and red monopthongs (M)). The /O/ quality (Vienna, M) and the /A/ quality (Lower Styria, M) are audible.
The impact of emotion on speech behavior is investigated in both studio and real-life recordings.
During a long-standing cooperation with the Commission for linguistics and communication sciences of the Austrian Academy of Sciences, a huge amount of material on Austrian German has been collected.
Phonological and phonetic reduction processes in Austrian German and in several other languages, including Albanian, Serbian, Romanian, Italian and Tibetan, is being investigated; formant measurements for vowel quality considerations are measured.
The Acoustics Research department has acquired over the years a huge amount of real-life recordings of Austrian dialect speakers (more than 200 different speakers); this material is used for sociophonetic as well as emotion and speech studies.
Several students are currently working on foreigner talk, especially with L1: Polish / L2: German.
First language acquisition
A relational child language database is being built containing full transcriptions in orthographic and phonetic format and several other devices for corpus analyses such as phonological and morphological information. Apart from the entries of the database are linked with the corresponding digital sound signals so that immediate access to the original data as well as automatic phonetic analyses are possible. The database will mainly contain data from the child Bernd (Austrian German) but also from other children speaking French, Polish and various other languages.

Acoustic phonetics involves the study of speech production and perception in regard to higher grammatical levels, especially phonology. The acoustic model of speech production computes the resonances of the vocal tract during different articulatory configurations. Formant frequencies, fundamental frequency, amplitude spectra and duration are used to describe language varieties phonetically. The results are interpreted within a phonological framework. The focus of our group lies on insufficiently described languages and language varieties.
We also develop new speech synthesis technology where our phonetic analyses are applied. The technologies range from acoustic and audio-visual speech synthesis, dialect and accent transformation to singing synthesis. In dialect synthesis we developed methods to generate in-between varieties that lie between a standard and a dialect, and thereby allow for a more realistic speech output production. Visual speech synthesis allows for the animation of a virtual character from textual input.
Although English is our primary working language, this document has been written in German and we cannot provide an English translation yet. We apologize for the inconvenience.
The public transportation system in Vienna is very good and usually safe. Single und bulk tickets are available at the ticket sales offices of the Vienna Transport Authority, at tobacconists and from vending machines in the underground stations. Tickets must be punched in a blue ticket cancelling machine in the tram or bus or at the barrier before you board the underground train. So if you don't have too much luggage, we recommend using it (though taxis are also reliable).
For your trip scheduling we refer you to Wienerlinien.
Car parking is a problem in central Vienna. You need to buy parking tickets in advance (for up to 1h30 available at tobaccionists) to be positioned above the dashboard visible in your car, and a few hours parking can be expensive. Therefore you should consider parking your car outside central Vienna and using public transportation. On special request contact us.
The conference takes place at the Bundeskriminalamt, Josef Holaubek Platz 1, 1090 Wien.
Here you can see the map.

Take the exit to the Vienna University of Economics and Business (WU), then keep to the right untill the entrance of the Bundeskriminalamt
In front of the arrival hall you will find the Vienna Ariport Lines. Tickets (€ 7,00) are available by the bus driver. Take the bus to Morzinplatz/Schwedenplatz. Here you can see the way from the bus station to the underground station Schwedenplatz. From there, take the U4 towards "Heiligenstadt" (tickets in the entrance hall: € 1,80,-), and exit at the 5th stop "Spittelau".

Call for Papers
You are invited to submit an abstract of a paper for presentation at the IAFPA 2011 Annual Conference by 15 April 2011 (24 April 2011 Deadline extension). Abstracts will be considered by the Scientific Committee and you should receive confirmation about whether the paper has been accepted by 31th May 2011. We welcome abstracts on topics such as:
A special session will be dedicated to the ongoing and important discussion of presenting evidence in court.
The topics listed above are not a complete list, and other topics would be welcome if they promote the aims of IAFPA, which are to 'foster research and provide a forum for the interchange of ideas and information on practice, development and research in forensic phonetics and acoustics set down and enforce standards of professional conduct and procedure for those involved in forensic phonetic and acoustic casework'.
Please note that the official language of the conference is English.
Abstracts should be a maximum of 2 pages in length.
In order to ensure that the abstracts have the same format for the conference programme, there is a template which you are asked to use. The template was devised by Anders Eriksson and his team for the 2006 Conference. It uses Microsoft Word and the rtf format to maximize the chances that it will produce the same end result regardless of whether you are a Mac, PC or Linux user. Please replace the text in the template with your own text. Please submit your abstract both as an rtf file and converted to a pdf file with fonts included. The rtf files will be reviewed minus the author information by the Scientific Committee.
The template can be downloaded by right-clicking the link below and selecting 'Save Link As...'.
