The point of SynthProject is to put as many samples of both hardware and software text-to-speech systems in one comprehensive, easily accessible resource.
Text-to-speech systems are used in various applications, including screen reading software for the visually impaired, calling centers, bus stations, airports, etc.
In my early days of surfing the net, I looked in vaine for a website which had demos of some of the more popular hardware synthesizers, including doubletalk, accent, audapter, and others, but could not find such a site.
Years later, I own, or have owned many of the hardware text-to-speech systems used in combination with leading screen readers for Dos and Windows operating systems. Some of these speech systems were before my time, so I have put together this resource so that others who may also be interested in such things can have a place to turn for text-to-speech demos, a comprehensive list of online interactive TTS websites, etc.
Here are demos and links to various text-to-speech systems.
These are demos of hardware synthesizers that I have either owned, or had access to, mostly recorded by me.

well, these are all the demos I currently have available. I'm currently looking for the following:

I, as a totally blind person, have always been fascinated by the different forms of speech output systems over the years.
Either there were no demos available for a particular synthesizer, or pages that claimed to have them were down.
Text-To-Speech demos

Hardware-based speech systems
accent factory demo from the original floppy disk
Audapter power-up message with default parameters (audapter system ready)
audapter reset to defaults
audapter internal demo

Braille 'n' speak 2000, spanish revision June 1999, default parameters
Braille hablado 2000 listo. Ayuda, uno pagina
Type 'n' speak, June 1997 revision defaults
braille lite m-20, revision 4.00 defaults
Braille lite m-40, February 2001 revision defaults
note: all legacy notetakers from Freedom Scientific BLV Group prior to the m-series were based on an artic speech chipset, while the m-series is based on the doubletalk from RC Systems. Freedom's newest notetaker line is based on eloquence from Eloquent Technologies, inc.
For authenticity, I have left the pause between DECTalk's initial boot and start of speech. During this time, DECTalk express runs internal test mode.
For more DECTalk stuff, please see the DECTalk page.
