voice AI agents and infrastructure
Recent window: last 5.2 months (2026-04-24 → 2026-09-28), compared with the prior 5.2 months.
These products offer models, APIs, and developer frameworks for building and optimizing low-latency conversational voice agents. They are primarily used by software engineers and product teams deploying interactive voice assistants and speech-driven applications. Unlike generic text-based LLM agent platforms, this cluster centers on real-time speech processing, audio routing, noise suppression, and voice performance monitoring.
