Eye On A.I. #320 Carter Huffman: Exploring The Architecture Behind Modulate's Next-Gen Voice AI
23 snips
Feb 11, 2026 Carter Huffman, CTO and co-founder of Modulate, builds real-time voice AI for emotion, intent, deception detection and large-scale moderation. He discusses why live voice understanding matters, the ensemble model architecture that beats foundation models, ultra-low latency scaling for millions of streams, and applications from gaming toxicity to deepfake and fraud detection.

Episode notes
Route To Specialized Models To Save Cost
- Route each audio segment to specialized, smaller models instead of one large model to save compute and improve accuracy.
- Use an orchestrator to select the right submodel for the current audio conditions in real time.
Design Ensembles For Millisecond Latency
- Low latency with ensembles requires splitting stateful decisions into fast feedforward passes plus slower feedback updates.
- Modulate pre-registers model choices and tolerates partial results to meet tight latency budgets.
Scale By Separating Feedforward From Feedback
- Treat each live stream as an independent feedforward computation to scale to millions of streams.
- Run asynchronous background feedback to update routing and improve future accuracy without blocking realtime responses.
