Software Development Kits

EduSpeakThe EduSpeak SDK is a speech recognition system for computer learning and training applications such as foreign language education, English as a second language (ESL), reading development and interactive tutoring, and corporate training and simulation. Access to its high-accuracy continuous speaker-independent speech recognition engine, is supported through several programming interfaces, such as Macromedia Director and Microsoft ActiveX, making it easy for developers of interactive, multimedia learning products to integrate voice input in their products. For developers of computer-aided language learning and ESL products, SRI's patented pronunciation scoring technology provides feedback to language learners to help them compare how their spoken word or phrase pronunciation compares with that of a native speaker of the language they are learning.
