PhonLab

The PhonLab at the Centre for General Linguistics (ZAS) offers very good employment and training opportunities for research and education in the fields of phonetics and phonology.

We have close cooperative relationships with Humboldt-University, Prof. Pompino-Marschall, the Institut of Phonetics at LMU Munich, Technical University Berlin, our French partner in Grenoble (GIPSA lab) and the University of Edinburgh.

The PhonLab was originally established with help of the Max Planck Association in 1994 and it was reconceived and rebuilt under the direction of Prof. Pompino-Marschall and Jörg Dreyer in its current home at Schützenstr.18. Our Lab supports all colleagues and students at the ZAS in their scientific research and fieldwork. We also have the resources to help outside researchers, if they have questions or problems about technical experiments. Please contact Jörg Dreyer.

The lab consists of an anechoic chamber and technical room as well as a computer room with 3 work places for students. The anechoic chamber also serves as an electromagnetic shielded studio with high acoustic quality for recording of speech.

Areas of research in experimental phonetics conducted at the PhonLab include:

  • acoustical analyses of speech
  • electromagnetic articulography
  • electromagnetic palatography
  • laryngography
  • intraoral pressure and airflow

The lab contains several computers, including one which controls the 10-channel-EMA-system AG100 used to measure movements of tongue, lips and jaw, and another PC which works with the laryngograph used to capture data from the vibration of vocal folds in the larynx. The laryngograph is mainly used in student training. We can also use the system to measure voice intonation and laryngeal movement.

With our new 3D-Articulograph AG500 from Carstens medicine electronics, bought in summer 2008, we successfully carried out experiments with italian speakers for our phonetics-project.

In the lab we have another computer to run our electropalatographic system  EPG 3.0, used to record tongue-palate-contacts (artificial palate with 62 electrodes).

For intraoral measurement of air pressure we have developed a special electrical system. It is based on a small (13mm x 1,5mm) pressure transducer from Endevco, which is electronically coupled with a pressure transducer system from SCICON RD. The pressure sensors for the experiments are glued on the hard palate or are glued with a short piece of plastic tube on an artificial palate. This can be used in combination with EPG or EMA.

In cooperation with LMU Munich we have worked with a new inductotrace system, which allows us to measure the thorax expansion during respiration. This can be used in combination with recording of intraoral pressure while speaking.

We have long experience in using Praat (Boersma,Weenink) for analysing acoustical signals and PCquirer for pressure and airflow measurements on PC and MacIntosh.

For many other applications we are using software MATLAB/SIMULINK.

For recording, processing, analysing, and reproduction of acoustical signals in particular, we have a complete set of digital and analogue sound studio equipment including portable flash-recorders, DAT-recorders, digital soundcards, tapedecks, analogue bandmachines for older recordings, filter/equalizer, amplifier, loudspeaker, record- and CD-player, electronic measurement techniques, signal generator, oscilloscope as well as the corresponding high-grade microphone technology  for use in the lab or in fieldwork.

We also provide video camera and recorder equipment, used for instance in long term investigation of language aquisition.
