Speech, Language, and Audio
From soothing a crying baby to rallying millions to a cause, the human voice is a powerful tool. Speech and language allow us to interact naturally with a variety of computing applications, as well as providing a wealth of information about our relationships, intentions, health, and emotional state.
For government and commercial clients, SRI's Speech Technology and Research (STAR) Laboratory creates software for signal processing, phonetics, mathematical modeling, acoustics, data indexing and mining, language translation, and computer-aided learning. For tailored client solutions, SRI offers advanced product prototyping and customization and turnkey product development.
SRI also develops speech and audio technology for use in challenging audio environments, where it can be extremely difficult to understand the speech, identify the speaker or language, or even just detect whether speech is present. SRI has honed speaker identification and verification techniques for biometric applications.
Market leader Nuance, now a billion-plus-dollar company, was spun off from SRI in the 1990s to exploit STAR Laboratory technology. Today, developers incorporate SRI speech technologies, packaged as software development kits, into their products and services.
SRI is finding new ways to detect altered and tampered video.
SRI is investigating whether and how students’ speech can be used to determine how well they collaborate during interactive learning activities.
SRI is improving the robustness of speech processing technologies and transitioning them to government partners for use in highly noisy operational audio conditions.
SRI is developing software that can uniquely identify a system’s users from spoken and written inputs, rather than using passwords.
