Multi-agent systems + Voice agents and agent interoperability (awareness)

Comes up in: AI engineering, AI system design

This concept is being written. It gets the full five steps — explanation, predict, interview angle, practice with tests, and review cards. Here is exactly what it will cover, so you can study it elsewhere in the meantime.

What it covers

  • orchestrator + sub-agents
  • parallel research
  • handoffs
  • shared vs isolated context
  • costs (token multiplication) and failure modes
  • when a single agent is better (cite Anthropic multi-agent research post, 2025)
  • realtime voice pipelines (speech-to-text → LLM → text-to-speech vs speech-to-speech models)
  • latency budgets and turn-taking
  • interruptions
  • agent-to-agent protocols such as A2A (status, facts) vs MCP

What you will practise

  • orchestrator with 2 research sub-agents
  • compare cost and quality
  • latency budget for a voice support agent

Interview questions this answers

  • When is a multi-agent architecture worth it?
  • What are the failure modes of multi-agent systems?
