What AI voice agent development actually requires in 2026
2026 stack: Vapi, Retell, or Bland for managed voice infra; Deepgram or AssemblyAI for STT; ElevenLabs or Cartesia for TTS; OpenAI/Anthropic for the brain; Twilio or Telnyx for telephony. Sub-2-second latency requires WebRTC + streaming throughout the pipeline. Voice engineers must tune for latency (sub-1.5s round-trip), barge-in handling (customer interrupts the bot), and conversation repair patterns. Standard chatbot devs build voice agents that feel like a 1990s IVR — long pauses, missed cues, frustrated users hanging up at 30%.
