Free University of Bozen-Bolzano

Alpine Laboratory of Phonetic Sciences

Research at ALPs

In our laboratory we carry out the following research projects:

  • the sociophonetic variation of /r/ in mono- and bilingual speakers from South Tyrol;
  • the sociophonetic variation of /s/ in mono- and bilingual speakers from South Tyrol;
  • the sociophonetic variation of dental affricates in monolingual speakers from Bozen-Bolzano;
  • Voice Onset Time in mono- and bilingual speakers from South Tyrol; the structural complexity related to /s/C(C) consonant clusters in mono- and bilingual speakers from South Tyrol.

Equipment

Hardware

  • Puma Pro30 - This soundproof chamber is an essential part of the ALPs. It provides a noise-reduced and echo-free environment. The chamber is used for recordings that require highly controlled acoustic conditions.
  • Ultrasonix SonixTablet - This compact ultrasound system with a 19" touch screen allows to capture high frame rate images of the tongue for use in fine grained phonetic analysis.
  • SonoSite 180 - This portable ultrasound system is ideal for sociophonetic fieldwork and for UTI training.
  • Probe Stabilisation Headset - This helmet keeps the head of the speaker and the ultrasound transducer in constant relationship.
  • SyncBrightUp - This unit from Articulate Instruments Ltd synchronizes audio and video inputs.
  • GoPro Hero3 - This helmet camera is mounted on the Probe Stabilisation Headset to image lip movement.
  • Zoom H2, H4 - These handy recorders are ideal for high quality recordings outside the ALPs.

Software

  • AAA – Articulate Assistant Advanced - This software from Articulate Instruments Ltd is used to elicit, record and analyse UTI data.
  • Multispeech - This software from KayElemetrics is used to analyse acoustic data
