Using Voice Key with SuperLab for Windows 2.0
Last Revision: January 18, 2005

The information in this article applies to:

• SuperLab Pro for Windows version 1 and version 2 users who want to use the built-in microphone as voice key

Summary

Unfortunately, SuperLab Pro for Windows' implementation of a software voice key has proved unreliable. It might be OK to use for educational purpose, but users are advised to avoid using it for research.

Note: a "software voice key" refers to when a microphone is plugged into your computer's sound card (as opposed to a specialized voice key hardware device)

This tech note does not affect SuperLab Pro for Macintosh.

Technical Details

The main problem with the implementation of the voice key in SuperLab Pro for Windows is that it does not work reliably across all Windows-based computers.  Some of the symptoms reported are:

• It doesn't work at all on some computers

• It works on some computers but the timing is not reliable

• It works fine on some computers

The symptoms exhibited depend on many factors including the make and model of the sound card, the drivers supplied with it, and the version Windows installed.

Cedrus has developed SV-1, a voice key hardware device to remedy this issue. We apologize to all our users who experienced any problems with using the software voice key.
