The human voice is a powerful tool. SRI’s speech and language technologies not only allow us to interact more naturally with computing applications—they also provide a wealth of actionable information about our intentions, health and emotional state.

Platforms
Open Language Interface for Voice Exploitation (OLIVE)
Novel speech processing technology leverages AI algorithms to enable speech activity detection in high levels of noise and distortion.
SenSay
Real-time speaker state platform estimates speaker state—such as emotion, sentiment, cognition, health, mental health and communication quality—in a range of end applications.
DynaSpeak® speech recognition engine
Small-footprint, high-accuracy engine incorporates patented techniques that increase recognition performance using speaker adaptation, microphone adaptation, end-of- speech detection, distributed speech recognition and noise robustness.
EduSpeak® speech recognition toolkit
Toolkit specifically designed for language-learning applications and other educational and training software. Works for both adult and child voices, it excels at recognizing native and non-native speakers.
SRI Language Modeling (SRILM)
Toolkit helps build and apply statistical language models for speech recognition, statistical tagging and segmentation, and machine translation. Can be downloaded and used free of charge.

“I love to work here because SRI International is a place where you find people smarter and nicer than you. They keep me pushing in the right direction and challenging me every day, but with respect and kindness. What else can you ask for?”
