Soniox vs Deepgram
for Azerbaijani speech-to-text

Higher accuracy in real-world Azerbaijani, real-time features, and in-stream translation that Deepgram can't match.

Developers choose Soniox for accuracy in Azerbaijani speech

Azerbaijani is spoken by 23 million people worldwide — primarily in Azerbaijan, with speakers around the world. Soniox delivers production-ready transcription and translation for Azerbaijani, handling regional accents, code-switching, and real-world audio conditions. Deepgram lists Azerbaijani as supported, but benchmark results show far higher error rates compared to Soniox.

Developers often like Deepgram for getting started quickly but often have to sacrifice accuracy, streaming speed, and key features. In real-world Azerbaijani audio, which can include accents, rapid speech, and overlapping speakers, errors increase, streaming lags, and translation isn't included. Soniox offers one API that transcribes and translates Azerbaijani (and 60+ others) with higher accuracy and smoother real-time performance, so your app instantly works worldwide.

It just gets the words right — any language, any accent, any context. That’s what accuracy is supposed to look like.

More than transcription. Accuracy, speed, and translation built in.

Accuracy that holds up in Azerbaijani.

Soniox consistently delivers top results for Azerbaijani transcripts. That means cleaner transcripts, less post-editing, and apps you can actually trust in production.

Real-time Azerbaijani streaming.

Apps stay smooth and responsive with token-level updates in milliseconds. You still get full control with refinements, finalization, and endpoint detection.

Deepgram only streams by the sentence, so transcripts lag and jump.

Global-ready from the start.

One API covers transcription and two-way translation for Azerbaijani and 60+ others.

Deepgram requires separate services and can't handle translation.

Simple pricing that scales.

Soniox pricing stays flat: ~$0.10–0.12/hr with every feature included. No tiers, upsells, or surprises as you grow.

Deepgram charges more – and still doesn't include translation.

Pay 2-3x less than Deepgram

With Soniox, transcription, translation, diarization, timestamps, and confidence are all included in one price. Deepgram charges more per tier and doesn't bundle translation at all.

  • Soniox bills per token, which works out to the effective hourly rates above for typical conversational speech.
  • Deepgram pricing varies by tier: lower-cost "Nova" models are less accurate, while higher-cost "Enhanced" adds expense. Translation requires a separate service.
  • All comparisons use publicly listed rates as of 2025.
