It was super easy to integrate with AssemblyAI and it provides accurate translations in multiple languages
AssemblyAI is great! Their speech-to-text API is a beast, making it so easy to transcribe audio for our app. The docs are spot-on, super clear, and got us up and running fast. Plus, the control we get over features like speaker detection and real-time transcription is next-level.
We used Assembly for transcription in SnapLinear because they offer speaker diarization and real-time transcription
Reliable, accurate transcription and easy integration made it the backbone of Nexalytics’ speech-to-text layer.
Lightning-fast and accurate subtitle generation. Their speech-to-text API creates perfectly synced captions that save our users hours of manual work.
Super accurate and easy to integrate, better pricing and dev experience compared to other transcription APIs.
Tried it via API, the product does his job wonderfully. Maybe a small note regarding the fierce competition in the field is needed, 11Labs is still the elephant in the room
One of the most cost-effective streaming speech-to-text options I've seen. Integrated super well with my application, and transcription quality was great!
Hands down SOTA accuracy, especially with challanging audio with lots of speakers and lots of noise. Very impressed, a massive step up over on-device transcription and noticably better than OpenAI's Whisper.
AssemblyAI's experience has been great for us. We originally used Deepgram, but the contrast from a performance, cost, and support perspective made the decision easy.
AssemblyAI isn’t just a transcription engine—it’s a full-fledged audio intelligence platform. With top-tier accuracy, rich audio features, real-time capabilities, scalable APIs, and rapid innovation, it's an incredible asset for anyone working with voice/video data.
If you're a developer, podcaster, researcher, or enterprise looking to build or analyze audio at scale, AssemblyAI is absolutely worth exploring.
We rely on AssemblyAI’s speech-to-text API to power ConversAI’s voice mode. Their accuracy and low-latency transcription let us give real-time feedback on your spoken responses—no clunky delays or guesswork
AssemblyAI is a great transcription service! It recognizes audio very accurately and produces good text. We use it in our summary bot.
