Yes, we’re rebranding many of our former Azure AI Services as Foundry Tools. This shift reflects a broader platform unification under Foundry, and signals that these services are now positioned as core tools for building agentic AI applications.
Azure Speech in Foundry Tools still offers the same powerful capabilities—like speech recognition, text-to-speech, and translation—but is now part of a cohesive toolkit designed for developers building intelligent agents.
The rebrand helps clarify how these APIs fit into the Foundry ecosystem and makes it easier to discover, orchestrate, and integrate them into modern AI workflows. -
