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.

Resilient Data Augmentation Approaches to Multimodal Verification in the News Domain
With the advent of generative adversarial networks and misinformation in social media, there has been increased interest in multimodal verification. Image-text verification typically involves determining whether a caption and an image correspond with each other. Building on multimodal embedding techniques, we show that data augmentation via two distinct approaches improves results: entity linking and cross-domain local similarity scaling. We refer to the approaches as resilient because we show state-of-the-art results against manipulations specifically designed to thwart the exact multimodal embeddings we are using as the basis for all of our features.

Natural Language Access: When Reasoning Makes Sense
Natural language is one of the more appealing ways by which people can interact with computers, but up to now its application has been severely constrained. We argue that to use natural language effectively, we must have both a deep understanding of the subject domain and a general-purpose reasoning capability. We illustrate the issues with SAP-QUEST, a proof-of-concept system for natural language question answering over a set of data sources for business enterprise applications, but the argument can be applied more generally to dialogue-style interfaces over a variety of subject domains.

Wideband Spectral Monitoring Using Deep Learning
We present a system to perform spectral monitoring of a wide band of 666.5 MHz, located within a range of 6 GHz of Radio Frequency (RF) bandwidth, using state-of-the-art deep learning approaches.
“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?”
