Guide to lab computing

All Lab workstations automatically mount shared disk space as the guest user. This shared space is often referred to as the PDrive since it is mounted as drive letter P: on Windows.

Tools and libraries

• ifcformant -- a command line tool for extracting formant measurements, as described in Ueda, Yuichi; Hamakawa, Tomoya; Sakata, Tadashi; Hario, Syota Hario; Watanabe, Akira (2007) A real-time formant tracker based on the inverse filter control method, Acoustical Science and Technology of the Acoustical Science of Japan 28(4), 271-4. We are grateful to Yuichi Ueda for providing the C code which implements the algorithm. The user interface is provided by a Python wrapper around the authors' C code and was written by Ronald Sprouse.

Lab members can contact Ronald Sprouse for copies of this tool compiled for OS X, Windows, or Linux systems. Unfortunately we do not have permission to distribute the C code or this tool to the public.

Sample scripts

• meas_formants -- a python script for reading a Praat textgrid and performing formant analysis on vowel tokens
