Acoustic Analysis Software
PCQuirer
- PCQuirer is a comprehensive signal analysis program available throuch Scicon Research and Development (there is
also a Macintosh counterpart available through Scion). Important uses of this ssoftware include measuring oral airflow and pressure as well as nasal airflow and pressure. - Currently, PCQuirer is run on three of the Lab's computers, all of which run Windows: the first on the computer for the recording booth (where the PCQuirer A/D converter, oral mask, and nasal mask are set up), the second on the laptop (for field use), and the third on another computer in the analysis section of the Lab.

From the Scicon Website:...PitchWorks is an extension of these programs to provide an interface for multi-tiering, TOBI style labeling with automatic Pitch and Intensity calculation. PitchWorks uses two methods of pitch calculation, Cepstral and auto correlation...A variety of file formats is read directly, including, esps, LDC, NIST,...
Pitchworks is used by Lab members to accurately annotate the pitch of speech files. Much of its functionality is also found in PRAAT, yet some functionality is specific to Pitchworks. The left shows an example of its ability to annotate speech files. Two of the Lab's Windows computers which are currently running PitchWorks software.

- Lab members use Praat for speech analysis and segmentation, yet it offers a slew of other features: implementations of
learning algorithms, graphics production for high quality images and papers, scriptability, listening experiment functionality, statistics, speech manipulation, and speech synthesis. The Praat program was created by Paul Boersma and David Weenink of the Institute of Phonetics Sciences of the University of Amsterdam. It is distributed freely (and widely) and matches many of the capabilities found in proprietary software suites. It is also very portable software and runs on the Lab's Linux, Windows, and Macintosh systems.
