EduSpeak is a speech recognition toolkit specifically designed for developers of language-learning applications (such as for English as a Second Language, or ESL) and other educational and training software. The technology is available for license from SRI.
Increasingly, educators, publishers, employers, and consumers use interactive, computer-based materials to teach or train students of all ages. Adding speech recognition is a principal way to enhance these materials’ interactivity and ultimate effectiveness. However, general-purpose speech recognition systems lack the broad array of multimedia development interfaces essential for use with diverse educational platforms.
Unlike those general-purpose systems, EduSpeak works with Flash, Java, ActiveX, and C/C++. EduSpeak works for both adult and child voices. EduSpeak excels at recognizing both native and non-native speakers. And no other speech recognition system includes SRI’s patented human-calibrated pronunciation-scoring technology—a critical product differentiator for interactive language learning and assessment, and for reading instruction applications. EduSpeak is a product of SRI’s Speech Technology and Research Laboratory, a world leader in speech technology research and development.
