Acoustic Recording Software for Speech Production Experiments

by Geoffrey Stewart Morrison

This free software presents written prompts onscreen and recordsspoken responses. Prompts are presented in randomised blocks andthe number of repetitions can be selected. The researcher controlsthe progress of the experiment and monitors the quality of therecording. For each response recording, a raw waveform is displayedonscreen, and the researcher has the option of listening to therecording (the speaker does not hear the playback), accepting therecording, rejecting the recording, or quitting the experiment. If arecording is rejected, the prompt is presented again later in theexperiment. This ensures that the required number of tokens arerecorded with acceptable quality. Each recording is saved to aseparate file using a systematic file-naming convention for easyprocessing in acoustic analysis software. If the experiment isinterrupted no data are lost. If the experiment is resumed the speakercan either complete the missing prompts only or can start again at thebeginning. Prior to the experiment, the instructions are presented inwritten form onscreen, and in audio form from prerecorded readings ofthe instructions. The speaker also completes a short practice versionof the experiment.

The software runs under 32-bit Windows XP (Tablet version of XPworks, don’t know whether it will run under Vista). The software isdistributed as compiled Matlab (a Matlab licence is NOT required).Version 6 has been field-tested (data collected from 35 speakers) andfound to be stable. Future versions may include additional featuresrequested by users.
