Hey everyone,
I’m Solomon — the creator of GetEchoSpace, a voice AI widget that lets any website host real-time audio conversations for support, live shopping, or community.
While building it, I constantly had to combine tools for ASR, text-to-speech, and LLMs — juggling APIs from different vendors and testing pipelines just to get a working flow.
At some point, it hit me:
Everyone building in voice AI is reinventing the same workflows from scratch.
The Problem
There are incredible voice AI tools out there — from OpenAI’s speech APIs to ElevenLabs, Whisper, Speechmatics, and more.
But there’s no central place to discover, compare, and see how they connect in real-world setups.
Builders like me spend hours figuring out:
- which ASR integrates best with Twilio,
- how to pass data between TTS and LLMs,
- and how to deploy these flows in production.
Enter echostack
So I started building echostack — a public directory of voice AI tools and ready-made “stacks.”
Think of it as Zapier templates or Stack Overflow for voice AI workflows.
Each stack shows how to combine tools (e.g., Retell + OpenAI + Twilio + GCP ASR) to achieve real outcomes — like multilingual dubbing, customer triage bots, or AI-powered voice assistants.
The goal:
help developers and AI builders spend less time wiring tools, and more time shipping value.
Tech Behind the MVP
The MVP is built with:
- Next.js 15 (App Router)
- TypeScript + Tailwind
- Supabase (for data)
- Zapier & n8n export support planned for v0.2
What’s Live Now
You can explore:
- Featured voice AI tools
- Early “stacks” (like multilingual dubbing or real-time triage bots)
- Newsletter signup for updates as new stacks drop
I’d love your feedback
If you’re building with Voice-AI or integrating ASR/TTS/LLM tools, I’d love to hear:
- What workflows or “stacks” you’d want to see next
- Which tools are must-haves for you
- Whether you prefer no-code or code-level examples
What’s Next?
- Expand to more tools and stacks
- Add semantic search and tagging
- Support Zapier/n8n exports
- Launch the curated Voice-AI Stacks Newsletter
If that sounds interesting, you can check it out or share feedback directly on echostack.
