What does multimodal actually mean?

Multimodal model means speech and text work together simultaneously, each informing the other in real-time.

Emotional Conditioning

These models preserve emotion and intention by avoiding the lossy conversion to text, allowing for sophisticated speech interactions that feel authentic

Instantaneous inference speeds that ultimately close the gap toward natural human-like conversation are made possible by removing the serial processing delays present in cascaded pipelines.

One unified model that replaces distinct transcription and synthesis stacks reduces parameter redundancy, which lowers operating costs and speeds up hardware inference.

What does Full Duplex mean?

Most voice AI is half duplex- you speak, it waits. It speaks, you wait. Like a walkie-talkie. Full duplex means both sides can listen and speak simultaneously. Like a phone call. The way humans actually talk.

Half duplex

How AI Talks Now

One side talks while the other waits. The AI cannot hear interruptions while responding, and cannot process your speech while you're still talking.

Full duplex

Asynchronous Thinking

Both parties can speak and listen simultaneously, both hears you in real-time, even while generating responses enabling natural conversation flow with overlapping speech
