resources
Reach every market from one recording. Translate transcripts into 86 languages in the same request that produces them, in the register your audience expects.
Enable Translation in your transcription request, or translate a transcript you already have, and receive full-text translations that preserve the original meaning and context.
Translate into 86 languages, and into several of them at once from the same request, without a separate translation vendor.
Choose the register that fits your audience, so translated output sounds the way your product speaks.
With speaker labels on, receive translated utterances attributed to each speaker in the conversation.
Localize what you already captured, without a second pipeline or a translation vendor.
Investments in STT improvements always pay for themselves, since it is such a critical building block of the voice pipeline.
Lindsay Liu
Co-Founder & CEO, Super
If you have an hour of content, the difference between 99% accuracy and 97% accuracy, it's a lot of time for that person to review. So you could cut down their workflow from taking half an hour, to 20 minutes, to 15 minutes — it's huge, right?
Joshua Grossberg
CTO, Kapwing
AssemblyAI's managed API endpoint and diarization won me over — something Whisper couldn't provide.
Josh Mohrer
Founder, Wave.co
We needed a provider that could scale with us — offering unlimited concurrent streams, fair pricing, and responsive support.
Mark Barbir
CEO, Earmark
The transcription accuracy, reliability, and speed of AssemblyAI's API have greatly enhanced our operations.
Raj Shankar
SVP Product, Calabrio
Our free to paid conversion rate doubled after implementing AssemblyAI.
Colin Treseler
Founder & CEO, Supernormal
The accuracy was strong, but the great documentation and unique models like Auto Chapters and Sentiment Analysis is what really won us over.
Nathan Webb
Product Manager, Aloware
Calls are and will remain a pertinent part of the customer service journey. Customer service isn't moving entirely to chatbots or chat interactions.
