The Emic 2 Text-to-Speech Module is a multi-language voice synthesizer that converts a stream of digital text into natural sounding speech. Using the universally recognized DECtalk text-to-speech synthesizer engine, Emic 2 provides speech synthesis capabilities for any embedded system via a simple command-based interface.
