I am really happy with AssemblyAI - Speech to Text API because it supports many languages with accurate results. My app on the app store uses AssemblyAI's API, and it has over 10k active users who benefit from the multilanguage support and speaker detection it provides.

I find the initial setup very easy, using their JavaScript SDK on my Node.js server with just maybe 5-10 lines of code. Review collected by and hosted on G2.com.

Company Owner Small-Business (50 or fewer emp.) 9/24/2025 "Powerful, Developer-Friendly STT with Room to Evolve" 5/5 What do you like best about AssemblyAI - Speech to Text API? \* The accuracy is excellent, even on noisy audio or with multiple speakers. Many of the transcripts required minimal editing. \* Speaker diarisation works reliably — being able to split out who said what is a big plus in multi-person recordings. \* Ease of integration is a standout: the API is well documented, the onboarding is smooth, and I got up and running quickly. \* The pricing model is fair and transparent — you pay for usage rather than being locked into a subscription. \* Advanced features like Word Boost / keyword prompting, PII redaction, and language auto-detection give useful flexibility for real-world use cases. Review collected by and hosted on G2.com. What do you dislike about AssemblyAI - Speech to Text API? \* The latency/response times can vary under load, which makes it less predictable for real-time needs. \* Customisation is somewhat limited: fine-tuning for domain-specific vocabulary or acoustic quirks isn’t as deep as one might hope. \* The API returns many fields in the response; for simpler workflows, that extra metadata can add overhead. \* The 10-hour audio length limit (for some endpoints) feels restrictive for very long recordings. \* In certain regions (e.g. Europe), some features are either missing or still in development.
