Code Factory offers the Eloquence text to speech synthesizer which is compatible with any SAPI 5 platform. This means that it will work with screen readers like Narrator and NVDA. Try it out free for seven days and see if you agree that it makes an enormous difference in the performance of Narrator. Go here to read more about the product and download it to your PC. The license allows you to use the synthesizer on up to three PC’s at once, so you need to deactivate it and reactivate it on a different computer, that is perfectly fine. This allows people to use the synthesizer at school, at the library, or while working on other people’s computers.
