Our empathic voice interface (EVI) is built on a state-of-the-art speech-language model. This allows EVI to converse quickly and fluently, understand what emotions the user is expressing in their voice, and generate any tone of voice in response. It can be interrupted at any time and can chime in at the right moments. EVI can simulate a wide range of personalities – allowing you to build custom voice AIs for any use case. Experience the most realistic AI voice.

Built on over a decade of emotion science research, EVI's speech-language model detects subtle vocal cues in the user’s voice and adjusts its responses based on the context.

• Responds with appropriate tone—sympathetic, enthusiastic, or the right emotion for the situation

• Adapts its conversation style based on user engagement and emotional cues

• Optimized for user satisfaction through reinforcement learning for human expression
