Hey PH community,
I'm Aishwarya, the product marketing manager for Async.ai. Today, I'd like to introduce Async API, our premium voice AI technology designed especially for developers.
What is Async AI?
Async is the advanced AI technology that has been silently powering Podcastle’s magic for years and is now stepping into the spotlight and becoming available to developers worldwide.
At Podcastle, we've spent years at the forefront of AI text-to-speech innovation, but we kept encountering the same frustration — existing solutions were either too complex, too expensive, or too limiting for the creative minds building tomorrow's applications.
That's why we built Async API with a developer-first philosophy from day one. Every decision, from our 3-second voice cloning to our straightforward pricing model, was made by asking: "What would make a developer's life easier?"
Async AI offers:
User-friendly API
Realistic, expressive voices that reflect human intonation and emotional nuances with remarkable accuracy.
Voice cloning in just 3 seconds.
Supports over 20 languages (coming soon!) and countless voice styles.
Developer-friendly prices.
Powered by our latest asyncFlow v1.0 model, we deliver premium voice quality at competitive prices. With advanced emotional inflexion, rhythm control, low latency responses, and reliable uptime, our technology seamlessly integrates from prototype to production-ready solutions.
Whether you're building interactive experiences, accessibility tools, or content at scale, our AI voices truly connect with your audience.
Check us out at async.ai today! To celebrate this launch, we are offering credits for $10 if you sign up today!
Thanks for all the love you've shown for Podcastle and Async

Love it, upvoted. I just tested it and it works PERFECT! Flow was incredibly fast, that's what I like : in a matter of seconds I could generate my first test. Going to keep this in mind.
ONLY THING missing: select the language on the generator form (screen).
Best!
Podcastle
Thanks so much for the support@codewithguillaume!
We are delighted that you loved our product! We have now released the API for English, and we will be launching TTS generation for over 20 languages very soon! Stay tuned for more details.
okay it's def my favorite product today
Hey Podcastle team,
How do you ensure low latency while maintaining voice quality? What’s your typical response time?
Thanks.
Async Voice AI
@lilit_grigoryan18 At Async, we’ve optimized our pipeline end-to-end to ensure low latency without compromising voice quality. We use a streaming architecture that generates and delivers audio in real time as text is received, instead of waiting for full synthesis.
Our models are lightweight yet high-quality. On average, audio starts streaming within 150–250ms of the request.

Great product, congrats!

Can't wait to test it later this week 🤩🤩🤩
Podcastle
@petr_antropov1 Can't wait for you to experience it!
Thanks for your support!
Impressive offering! The focus on natural, expressive voice output really sets this apart — love how easy the API makes it to bring high-quality speech to any app. A great upgrade for anything from customer service to creative projects.
Podcastle
@supa_l Thank you! We have invested considerable time and effort to ensure our AI technology produces speech that sounds human. We also aim to be accessible to all developers and relevant for every type of project.
Hey Podcastle team, congrats on the launch—really exciting stuff!
I have a quick question—what’s the minimum sample quality needed for good voice cloning results?
Thanks
Podcastle
Thanks so much@marta_karapetyan!
Async offers instant voice cloning with just 3 seconds of recording. It creates realistic voice clones capturing tone, pronunciation, and emotion with remarkable accuracy.
What inspired the Podcastle team to create Async API? What problem were you trying to solve?
Podcastle
@mariam_ghushchyan thats a great question!
We'd built incredible AI voice technology for Podcastle’s AI Voice hub, designed for content creators and podcasters. But we also understood that there is a gap in the market when it comes a good solutions for developers.
Talented developers would reach out excited about voice AI possibilities, only to hit walls with existing solutions. They were either too expensive, too complex to integrate, or required massive technical overhead that killed innovation before it started.
We realized we had the expertise to change this. At Podcastle, we'd already solved the hard technical challenges around voice quality, latency, and multilingual support. So we asked ourselves: "What if we rebuilt this from scratch, but designed it exclusively for developers?"
That's how Async Voice AI API was born.
Looking forward to more language!
Podcastle
@zeyang Absolutely! It's coming soon. Stay tuned for updates!
How does this compare to hiring voice actors for content creation?
Podcastle
@lidia_saroyan3 Hiring voice actors can be time-consuming and expensive.
With the Async Voice AI API, you can create voice clones with just 3 seconds of recording and generate realistic speech. It is a scalable solution for any creator or business, big or small! We offer unmatched pricing because we aspire to make text-to-speech generation accessible for everyone. Check us out on async.ai.

a good product, much congrats!

@egret_studio Thanks so much!
I've used other voice APIs, but this one feels polished and dev friendly. Low latency and fast cloning?
So many text-to-speech services nowadays. What's different between you and 11 labs, for instance?

Congrats on the launch, 🚀
What about accents? That would be great if that is supported too.

Async Voice API is mind-blowing. I tried Elevenlabs before, but the Async API is sooo much better. Sounds more human and has much more emotion, and is even cheaper. Amazing what you folks have built!
