The Speed of Thought: How Vercedo Achieves Sub-500ms Latency

The Latency Challenge

Have you ever spoken to a voice assistant and waited... and waited... for a response? That awkward silence kills the illusion. In sales, it kills the deal. Human conversation is fast, dynamic, and full of interruptions. To compete, an AI must be instant.

At Vercedo, we obsessed over this problem. We set a benchmark: sub-500ms latency. That's the threshold where a pause feels like a natural breath, not a processing delay.

Engineering for Speed

Achieving this required a complete rethink of the voice stack. Traditional systems chain together separate services for Speech-to-Text (STT), Large Language Model (LLM) processing, and Text-to-Speech (TTS). This relay race adds unavoidable lag.

Vercedo uses a proprietary, optimized pipeline that streams data in real-time. We don't wait for you to finish a sentence before we start processing. We predict, we pre-fetch, and we execute. Our websocket architecture ensures that packets of audio travel the shortest possible distance.

The Result: Natural Flow

The result is an AI that feels alive. It can handle interruptions ("Wait, hold on..."), back-channeling ("Uh-huh", "I see"), and rapid-fire questions without missing a beat. This isn't just a technical achievement; it's a user experience breakthrough.

When you use Vercedo, you're not talking to a computer. You're having a conversation.
