Voice in Copilot Studio Agents — How It Works (With Arabic Example)

Voice-enabled agents allow users to talk to AI agents instead of typing. With voice, your agent can:

  • Understand spoken language
  • Respond using speech
  • Handle phone calls
  • Support Arabic and multilingual conversations

Voice agents in Microsoft Copilot Studio typically use:

  • Azure Speech Service
  • Azure OpenAI Service
  • Power Platform
