- Microsoft Foundry adds a voice user simulator for pre-production voice-agent testing
Microsoft Foundry introduced a voice user simulator that plays the user in spoken conversations with a voice agent under test. Teams set a goal-driven scenario with facts and constraints, then vary acoustic conditions (voices, accents, ambient noise, telephonic audio) and optional conversational dynamics such as barge-in, backchannels, and clarification. The post says the tool is meant for pre-production evaluation where static scripts miss real-time speech behavior, and that available options depend on project and service configuration.
- Microsoft Foundry explains metadata-aware agentic RAG with Foundry IQ for SharePoint libraries
A Microsoft Foundry blog post argues that SharePoint libraries often store useful metadata such as root cause, severity, business unit and document type that never reaches retrieval, so RAG systems miss what a document is about. It describes a metadata-aware agentic RAG approach with Foundry IQ so agents can use that metadata alongside document text.

- Microsoft explains voice agents in Foundry Agent Service: architecture, trust boundaries and latency
A Microsoft Foundry blog post says voice agents in Foundry Agent Service consolidate speech services, real-time models, turn detection and tool orchestration into a versioned, managed agent, and covers identity, trust boundaries and real-audio latency.
- Microsoft details using LLMs to optimize retrieval beyond query text
A Microsoft Foundry blog post describes using LLMs to move retrieval from matching query text toward understanding user intent, since users rarely phrase requests the way documents are indexed.
