MetaSoul Inc. Awarded U.S. Patent for Core Emotion-Aware AI Voice Interaction Technology
Patent claims priority to a July 5, 2013 provisional and covers detecting emotion from a user’s voice and generating adaptive speech based on pitch and harmonics
“Emotion-aware voice is an interaction primitive. For home humanoids, adaptive tone builds safety and trust, especially with kids. This patent makes it scalable,” said Patrick Levy-Rosenthal, Founder
NEW YORK, NY, January 28, 2026 /24-7PressRelease/ — MetaSoul Inc., founded by Patrick Levy-Rosenthal, announced the issuance of U.S. Patent No. US 12,525,251 B2, titled “Method, system and program product for perceiving and computing emotions.”
The patent describes a mechanism for emotion aware AI: monitoring user input, determining the user’s emotional state using voice characteristics such as pitch and harmonics, and generating a response whose vocal pitch or harmonics are at least partly determined by that emotional state. It also describes an “emotion processing unit” (EPU) that can adopt different emotional states by loading emotional state information from memory, enabling a stateful emotional engine rather than a one-off tone shift.
MetaSoul views emotion-aware voice as an interaction primitive for the next wave of AI companions and humanoid robotics. As humanoid robots enter the home, voice becomes the front line of safety and trust, especially with kids. When voice adapts to emotion, robots can communicate more clearly, stay calmer in tense moments, and feel easier to live with day to day.
The newly issued patent expands MetaSoul’s growing family of emotion-aware computing IP, with priority to U.S. Provisional Application No. 61/812,260 filed July 5, 2013. US 12,525,251 B2 was filed Sept. 24, 2019.
MetaSoul intends to explore licensing discussions with leading AI companies and builders of AI companions and embodied robotics, including companies developing voice-first assistants, companion hardware, and humanoid home robots. No licensing agreements are being announced at this time.
