Stage AI Competitors

Built from a decade of voice and emotion research. To build emotionally intelligent voice AI, we first had to define what “good” sounds like – not just acoustically, but perceptually and in real human conversations. That led us to build the research infrastructure behind expressive, trustworthy voice AI: scientifically grounded datasets, speech models, evaluation frameworks, and human preference pipelines. Today, we make that infrastructure available to frontier labs and AI-native companies building the next generation of voice. Whether you’re building foundation models, fine-tuning voice agents, or evaluating production systems, Hume provides the tools to measure, improve, and align voice AI the way people actually experience them.

Affectiva is now a Smart Eye company. In June 2021 Smart Eye acquired Affectiva. We are merging the two companies to form a global AI powerhouse. Affectiva is on a mission to humanize technology. An MIT Media Lab spin-off, Affectiva created and defined the Emotion AI and Human Perception AI categories. Built on deep learning, computer vision, speech science and massive amounts of real-world data, Affectiva’s technology can detect nuanced human emotions, complex cognitive states, activities, interactions and objects people use. In automotive, Affectiva’s Interior Sensing AI is enabling leading car manufacturers, fleet managers and ridesharing companies to build next-generation mobility that understands the state of the driver, the cabin and the occupants in it. Affectiva’s technology is also used by 28 percent of the Fortune Global 500 companies to test consumer engagement with ads, videos and TV programming. For more information, visit www.affectiva.com.
