How to Setup and Use Setup Speech Recognition
Inquisit leverages the Microsoft Speech Recognition Engine to allow measurement of both latency and accuracy of spoken responses. To use Inquisit’s speech recognition capabilities, you must install version 4.0 of the Microsoft Speech Recognition Engine and and Speech API. If you have not already installed these components, you may do so here. Simply click on each link below and when prompted choose the option to "Run this program from its current location ".
The speech recognition functionality also requires that you have a sound card and a microphone. Almost any sound card will work for speech recognition and text-to-speech, including Sound Blaster™, Media Vision™, ESS Technology, cards that are compatible with the Microsoft® Windows Sound System, and the audio hardware built into multimedia computers. The quality of the microphone is a large determinant of speech recognition accuracy. Use a close-talk or headset microphone that is held close to the mouth or a medium-distance microphone that rests on the computer 30 to 60 centimeters away from the speaker. A headset microphone is needed for noisy environments. Speech recognition works best with close-talk microphones.
Before speech recognition will work, you must run the Microphone Wizard to adjust microphone input to appropriate levels. To run the Microphone Wizard, go to the Tools menu in Inquisit, select Speech Recognition, and then select Microphone Wizard.
