AI voice agents are evolving fast, opening up many possibilities for a new paradigm of customer interaction. In todayโs world, businesses still use scripted IVR menus and static call flows that frustrate customers and waste time. With AI voice agents, we can create natural conversations that adapt in real-time, handling thousands of concurrent calls with low latency.
There are many tools and possibilities for AI voice agents today, creating both exciting opportunities and a lot of noise. To cut through the confusion, hereโs a framework of six key tech stack layers you can leverage to build powerful, production-ready voice automation:
Letโs break it down: โฌ๏ธ
-
๐ฉ๐ผ๐ถ๐ฐ๐ฒ ๐ข๐ฟ๐ฐ๐ต๐ฒ๐๐๐ฟ๐ฎ๐๐ถ๐ผ๐ป ๐ฃ๐น๐ฎ๐๐ณ๐ผ๐ฟ๐บ Start with Retell AI as your foundation. No-code builder + developer API, 30+ languages, 99.99% uptime. โ Orchestrates STT, LLM, and TTS with sub-800ms latency for human-like conversations.
-
๐๐ต๐ผ๐ผ๐๐ฒ ๐ฌ๐ผ๐๐ฟ ๐๐๐ ๐๐ฟ๐ฎ๐ถ๐ป: Connect GPT-5 for complex reasoning, Gemini for long context, or custom models. The AI decides what to say, how to respond, and when to take action. โ Think: the intelligence that powers every decision your agent makes.
-
๐๐ฑ๐ฑ ๐ฉ๐ผ๐ถ๐ฐ๐ฒ & ๐ฃ๐ฒ๐ฟ๐๐ผ๐ป๐ฎ๐น๐ถ๐๐: Select TTS providers like ElevenLabs or Cartesia for natural voices. Clone your voice or choose from libraries, control speed, emotion, and tone. โ This is what makes your agent sound human, not robotic.
-
๐๐ป๐๐ฒ๐ด๐ฟ๐ฎ๐๐ฒ ๐ง๐ผ๐ผ๐น๐ & ๐๐ฎ๐๐ฎ: Connect calendars, CRMs and databases. Book appointments automatically, pull customer data during calls, update records in real-time. โ Like giving your agent hands to actually do things, not just talk.
-
๐๐๐๐ผ๐บ๐ฎ๐๐ฒ ๐ช๐ผ๐ฟ๐ธ๐ณ๐น๐ผ๐๐: Use n8n, Make, or Zapier to connect agents to existing systems. Trigger actions during or after calls, send emails, create tickets, build complex automations. โ Turns voice agents into full business process automation.
-
๐๐ฑ๐ฑ ๐ง๐ฒ๐น๐ฒ๐ฝ๐ต๐ผ๐ป๐ & ๐ฆ๐ฐ๐ฎ๐น๐ฒ: Connect phone numbers via Twilio, Telnyx, or Retellโs built-in telephony. Handle inbound and outbound calls, manage routing, scale to hundreds of concurrent calls. โ Most voice agents fail here โ this is production deployment, not demos.
Understanding this tech stack can improve deployment speed, reliability, and customer satisfaction, leading to more sophisticated and scalable AI voice automation.

This oneโs a serious drop for anyone building voice AI or multimodal agents. Maya Research just released ๐๐๐ฒ๐๐, a ๐๐ parameter emotional TTS model, open source under ๐๐ฉ๐๐๐ก๐ ๐.๐.
๐๏ธ ๐๐๐ง๐๐ซ๐๐ญ๐ ๐๐ง๐ฒ ๐ฌ๐ญ๐ฒ๐ฅ๐ ๐จ๐ ๐ฏ๐จ๐ข๐๐, from calm narrators to intense characters, even creature-like tones. ๐ฎโ๐จ ๐๐๐ฉ๐ญ๐ฎ๐ซ๐๐ฌ ๐ซ๐๐๐ฅ ๐๐ฆ๐จ๐ญ๐ข๐จ๐ง, it can laugh, sigh, whisper, rage, gasp, or cry naturally. โก ๐๐ข๐ ๐ก๐ญ๐ฐ๐๐ข๐ ๐ก๐ญ ๐๐ง๐ ๐๐๐ฌ๐ญ, runs smoothly on a single GPU with near-instant response. ๐ ๐๐๐๐ญ๐ฌ ๐ฌ๐๐ฏ๐๐ซ๐๐ฅ ๐ฉ๐ซ๐จ๐ฉ๐ซ๐ข๐๐ญ๐๐ซ๐ฒ ๐ฆ๐จ๐๐๐ฅ๐ฌ in clarity, emotion control, and versatility.
๐ก ๐๐ก๐ฒ ๐ข๐ญ ๐ฆ๐๐ญ๐ญ๐๐ซ๐ฌ You can finally deploy a production-ready, expressive TTS system without paying per second of audio. Itโs optimized for ๐ซ๐๐๐ฅ-๐ญ๐ข๐ฆ๐ ๐ฌ๐ญ๐ซ๐๐๐ฆ๐ข๐ง๐ , ๐ฏ๐๐๐ ๐ข๐ง๐ญ๐๐ ๐ซ๐๐ญ๐ข๐จ๐ง, ๐๐๐๐ ๐๐จ๐๐๐, and ๐๐ ๐ค๐๐ณ ๐จ๐ฎ๐ญ๐ฉ๐ฎ๐ญ, making it plug-and-play for any GenAI pipeline.
If youโre building serious AI solutions, just run it on ๐๐ฎ๐ง๐๐จ๐, ๐๐๐, or ๐๐๐ with a single A100 or 4090 GPU and itโs ready for production. This easily replaces several costly TTS APIs while giving you full control and customization.
Perfect for โ AI agents and assistants โ Podcast and audiobook generation โ Customer support bots with empathy โ Storytelling and character voices
This release just changed the TTS landscape, open, expressive, and deployable anywhere.
