📌

🌟 Hi Product Hunt family! We are excited to launch our product - Retell AI: an API for building human-like conversational voice AI. 🌎 With the advancement of generative AI, we have witnessed significant growth in chatbot products that dominate the market. Simultaneously, voice AI has improved to the extent that smooth conversations with AI are now feasible. Many applications such as AI receptionists, AI interviewers, and AI sales emerge. ❓ Many developers may think that making a voice AI is easy, "If you just stitch together speech-to-text, LLM, and text-to-speech, then you can get the LLM to talk, right?" 🤔 Turns out, it's not that simple. Developers spend hundreds of hours on this but end up with robotic voices, long latency, awkward cutoffs, and speaking over each other, etc. There's actually a lot more going on in human conversation, which feels so natural to us that we don't consciously realize it. We made an API that allows developers to create the most human-like voice agents in a day instead of months: ✅ Response time averages 800ms; ✅ Realistic voice; ✅ Can handle interruptions; ✅ Seamless turn-taking. 🙏 Please take a look at the demo video or try a live demo on https://retellai.com without signing in. Any thoughts? 🙌

The Demo is awesome. I've been thinking about voice as a new UI to distribute our product, but I'm still not sure how to execute it in a B2B SaaS... just wanted to comment it in case you know any case studies or use cases??? Congrats to the team for the launch (: keep it up!

"@alvarovillalb_ Thanks for the kudos on the demo! We're excited about voice interfaces, too. Currently, many of our customers use it for phone calls in various use cases, including receptionist services, data collection, and real estate. For web apps, popular applications include AI tutoring, AI coaching, and user interviews. We'd be happy to dive deeper into any of these use cases with you. Cheers for the support and interest! 🚀"

Congratulations on your launch. Voice generation is an important step to get everything out of LLMs, so I can't stress enough how useful this is. I am also thrilled to see that Retell AI can handle interruptions. An important feature I have been missing in similar tools. I'd be thrilled to know how you did this.

I have just checked out your app. It is not too bad. In its early stages - right? From what I can gather after building non-code AI chatbots myself on VoiceFlow and BotPress - well a little code with API endpoints to connect apps. From the dashboard, it is not clear how you would allow business owners to set it up easily with an LLM. I think it needs to work on this area. If it has more functionality to use the app properly for a business. Would be the best. Just my opinion. Overall, the voice is not bad - the voice is clear, real, and fast to respond. The conversational assistant is based on how well your LLM is - right? I think you should use an even more detailed conversational AI for the demo, where you can ask it more questions about the service. I am just trying to help. I review a ton of AI apps.

@ai_matt_ant Hi Matt, Thank you for the great advice! Actually, we're focusing solely on the voice component and recommend our users to integrate their own LLM instead of relying on a simple prompt to create an agent. Currently, we're in the early stages, but we're committed to pushing hard to develop the best voice AI that's indistinguishable from humans.

@evie_wang1 That is what I thought. So my suggestion is to add a few video tutorials, embed a template for quick install into private LLMs of your stand alone app (a few companies are doing this), and a few more functions. And your market will grow so much. Not all coders visit your site, I know a bit, but business owners might get put off as the UI is not intuitive enough for non-coders. Again just a suggestion.

No other API is close to Retells dev experience to be honest. I was able to prototype under an hour, with out of the box features: full pausing, natural voices, reminders, etc. This got me enough confidence to bet on Retell, though it's super early and not open source and to use this and start a critical public feature

Review Retell AI - Voice AI Agent?

Reviewers mostly see Retell AI as a practical, production-ready voice agent tool: they praise fast setup, intuitive UX, natural-sounding conversations, ready-made integrations, reporting, and stronger reliability at scale than some alternatives. Users say it works well for sales, support, scheduling, interviewing, and higher call volumes, with one noting customers sometimes do not realize they spoke to AI. The main reservations are narrower: some question how well quality holds up in complex, high-stakes calls and how much ongoing training is needed, while one user dislikes the pricing fit for midsize teams.
