Vendor.com's state of the art expression measurement models for the voice, face, and language.
Vendor.com's state of the art expression measurement models for the voice, face, and language are built on 10+ years of research and advances in computational approaches to emotion science (semantic space theory) pioneered by our team. Our expression measurement models are able to capture hundreds of dimensions of human expression in audio, video, and images.
Expressions are complex and multifaceted; they should not be treated as direct inferences of emotional experience.
The models were trained on human intensity ratings of large-scale, experimentally controlled emotional expression data gathered using the methods described in these papers: Deep learning reveals what vocal bursts express in different cultures and Deep learning reveals what facial expressions mean to people in different cultures.
While our models measure nuanced expressions that people most typically describe with emotion labels, it's important to remember that they are not a direct readout of what someone is experiencing. Sometimes, the outputs from facial and vocal models will show different emotional meanings, which is completely normal. Generally speaking, emotional experience is subjective and its expression is multimodal and context-dependent.
Our models measure 53 expressions identified through the subtleties of emotional language and 48 expressions discerned from facial cues, vocal bursts, and speech prosody.
