Soniox vs Deepgram
for Urdu speech-to-text

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

Developers choose Soniox for accuracy in Urdu speech

Urdu is spoken by 230 million people worldwide — across Pakistan, India, and beyond. Soniox delivers production-ready transcription and translation for Urdu, handling regional accents, code-switching, and real-world audio conditions. Deepgram lists Urdu 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 Urdu 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 Urdu (and 60+ others) with higher accuracy and smoother real-time performance, so your app instantly works worldwide.

Why teams choose Soniox over Deepgram for Urdu

Engineered for real-world accuracy in Urdu.

Soniox delivers production-grade accuracy in Urdu and 60+ languages. It understands fast, informal, accented speech in Urdu, and handles mixed-language phrases, spoken codes, and alphanumerics with precision that others miss.

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

Tony Wang,
Cofounder & Chief Revenue Officer at Agora

Deepgram’s accuracy drops outside of English, and it struggles with Urdu accents, code-switching, and real-world inputs like spelled-out names or numbers.

Unmatched speed and precision in Urdu.

Soniox streams every Urdu word in real time – accurate from the first sound, fluent to the last. Captions stay in sync, assistants respond instantly, and nothing gets lost mid-sentence.

"It’s so fast, captions appear before people even finish talking. Zero lag. No buffering. Nothing."

Dag-Inge Aas,
Head of AI at Tana

Deepgram streams by the sentence, not the word, which causes lag and loss of nuance in live applications.

Understand the rhythm of real Urdu speech.

Soniox knows when someone’s speaking, when they’ve stopped, and who’s talking, with built-in speaker separation, sentence boundary detection, and turn-taking awareness.

"Soniox knows who’s speaking and when each thought ends. The real-time transcripts read like true dialogue, not data dumps."

Adam Strom,
Co-Founder & President at Mobius MD

Deepgram lacks true conversational intelligence, and doesn’t support diarization in multilingual settings.

One API. Everything built in.

Urdu transcription, any-to-any translation, speaker separation, mixed-language support – all from a single model, endpoint, and call. Production-ready from day one.

Deepgram splits features across models, with no multilingual or translation support in a single stream.

Instant domain intelligence.

Soniox catches product names, acronyms, technical terms, and can be guided with your terminology — so output fits your users, product, and industry.

"Soniox captures complex medical terminology with high accuracy, helping physicians finalize notes faster and focus on patient care."

Max Malyk,
Vice President at DeliverHealth

Deepgram lacks domain intelligence, and doesn’t support vocab customization or translation control.

In-region performance for Urdu.

Soniox provides true in-region processing and storage for Urdu audio across multiple global deployments. Same model, same Urdu accuracy, same real-time performance.

Deepgram offers EU endpoints, but most processing remains centralized. Additional regions usually require dedicated enterprise deployments, and Urdu model parity can vary.
