CheckVocal: a program to facilitate checking the accuracy and response time of vocal responses from DMDX

CheckVocal is a Windows application that facilitates checking the accuracy and response time of recorded vocal responses in naming and other experimental tasks using the DMDX display and response collection software. CheckVocal handles all keeping-track and presents each recorded response audiovisually (as waveform, spectrogram, and sound played out) along with the correspondingprinted correct response andregistered responsetime. The user simply decides whether the response was correct, wrong, or missing, with a single mouse click advancing to the next response. Response ti me correction can be done manually or automatically (retriggering by apower threshold). Data safety and integrity is ensured by cross-checking and status saving, so t hat interruptedsessions can be resumed later. CheckVocal is freely available to the DMDX community via a dedicated Web page.
