Description
Sierra's multimodal agents bring voice, text, and visuals into the same customer conversation. Voice is for explaining what you need, a visual for comparing options side by side, and text for referencing something later. Instead of picking just one, the agent automatically shifts between modes as the conversation needs.

Could you build this?
No Sierra builds enterprise-grade conversational AI systems with real-time multimodal state switching, sub-second latency speech pipelines, and deep enterprise system integrations developed by high-end AI research teams.
What it would actually take: A distributed, low-latency agent architecture combining full-duplex WebRTC voice streaming, real-time multimodal state machines, dynamic UI generation, and deterministic enterprise guardrails. Building the synchronization layer that fluidly switches context across visual cards, voice interrupts, and text transcripts at enterprise scale requires a specialized team of systems and ML engineers.
