Covox Speech Thing Driver
This driver uses a printer port to play sounds. If a sound is playing, the printer port will be unavailable until the sound has finished playing. If the Print Manager (or some other application) is using the port, the driver will NOT play the sound. Like the internal speaker driver, the Speech Thing driver plays exclusively, so Windows will not run programs or respond to the user while sounds are playing. Unlike the internal speaker, the Speech Thing sounds much better. https://web.archive.org/web/20070318051751/http://www.tkk.fi/Misc/Electronics/circuits/dacs.html

Internal Speaker Driver for Windows 3.1 and Multimedia Windows 1.0
This Internal Speaker driver plays exclusively, so Windows will not run programs or respond to the user while sounds are playing. Unlike the Microsoft driver, interrupts are not disabled, so you don't have to worry about losing COMM port data or network connections. Even though it sounds OK with the interrupts enabled, if you do anything that causes a lot of interrupts (such as moving the mouse) the sound quality will suffer.
