Question: Can you suggest a platform that offers tools to analyze facial and vocal expressions to infer emotional state?

If you want a platform that can assess both facial and vocal cues to estimate emotional state, Hume is a good option. Hume offers an AI technology platform with three main tools: Empathic Voice Interface (EVI), Expression Measurement API, and Custom Model API. The EVI API uses an empathic large language model to identify and mimic human prosody and speaking patterns, including emotional expression. The Expression Measurement API identifies subtle vocal and facial expressions in audio, video and images with high-accuracy models. That's useful for estimating emotions in everything from AI research to social media and health and wellness.

Another interesting option is LiarLiar, which uses advanced AI processing to detect subtle signs of deception like micromovements, heart rate and other physiological signs of deception in videoconferences and video analysis. It uses remote photoplethysmography (rPPG) technology to measure heart rate changes and body language, emotion detection for facial expressions, and voice consistency analysis to detect changes in pitch and speech rate. The platform is designed to be easy to use and integrates with common videoconferencing tools like Zoom, Google Meet and Skype, so you can use it to improve people-reading skills and encourage honesty.
