DoubleTalk LT is the portable member of the DoubleTalk voice synthesizer family. Because it relies only on a simple external connection to your computer, DoubleTalk LT can go wherever you go. It works with virtually any PC or laptop equipped with an RS-232 serial port. Operation is from a 9 volt alkaline battery, or AC wall adapter (included).

Based on the RC8650 chipset, DoubleTalk LT is a totally self-contained voice synthesizer. Speaker, headphone jack, volume control, and serial interface are all built into the unit. No special software or drivers of any kind are required to use DoubleTalk LT; simply plug it into any serial port and send the text you would like read, just like it was a printer. With its superior responsiveness and intelligibility, and wide screen reader software support, it's no wonder why DoubleTalk LT has become the synthesizer of choice among thousands of visually-impaired PC users.
