Seeduplex is a full-duplex speech large language model developed by ByteDance's Seed team. Unlike traditional voice assistants that take turns speaking, Seeduplex listens and speaks simultaneously — just like a real human conversation.
Talk to AI the way you talk to a friend. No waiting for the AI to finish — interrupt mid-sentence and the AI adapts instantly. Response latency reduced by 250ms compared to traditional voice assistants.
Seeduplex filters out background noise — car navigation, TV, other people talking — with 50% fewer false responses. It understands what you say even in noisy environments.
Knows when you're pausing to think vs. when you've finished speaking. 40% fewer premature AI responses. The AI waits for you, not the other way around.
Seeduplex understands your environment — hearing a tour guide in the background, it connects that to your travel plans. Context-aware voice AI that goes beyond your words.
