Use of Introductory & Instructional Acoustic Measurement Tools for Speech: What do researchers use?
One of the discouraging things about using acoustic measures for speech analysis is the slow process of hand measurement. As part of an NIH grant (R43 DC010104), we are developing software modules that should help to automate some measurements, such as voice onset time (VOT) and vowel-space area, for both single files and larger data sets. We envision a situation in which the automatic tool contained in the module would report such measures from one or more audio files for easy input to statistical or other analysis software.For VOT, for instance, all intervals between release bursts and the following initiation of voicing contained in a speech file will be reported. These modules will be appended (as “plug-ins”) to existing analysis software tools.
We are conducting this survey in order to understand which software tools should be targeted for this capability.Our audience is researchers who have experience with introducing colleagues and/or students to the task of making acoustic measurements from speech.
