Soniox vs Azure
for Norwegian speech-to-text

Higher accuracy, real-time translation, and simpler integration than Azure for Norwegian.

Developers choose Soniox for accuracy in Norwegian

Norwegian is spoken by 5.3 million people worldwide — primarily in Norway, with speakers around the world. Developers need transcription and translation that can keep up. Soniox delivers Norwegian speech recognition that works in the real world: accurate across accents, fast in live streaming, and seamless with translation built-in.

Azure Speech-to-Text, while integrated with Microsoft's ecosystem, comes with tradeoffs: lower accuracy in noisy audio, laggier streaming, and more complexity when combining multiple services.

Soniox makes it simple. One API gives you transcription, two-way translation, diarization, timestamps, and confidence – without hidden costs or extra steps.

Higher accuracy in Norwegian speech

Soniox delivers production-ready accuracy on real-world speech: 8.4% WER in Norwegian vs 14.7% for Azure.

Streaming that feels live

Apps feel smooth and human with token-level updates, refinements, and full transcript control in Norwegian.

One API for transcription + translation

Soniox includes transcription + two-way translation and more in Norwegian with one call. Azure requires separate Translator and Custom Speech.

Pay 2-5x less than Azure

With Soniox, transcription, translation, diarization, timestamps, and confidence are all included in one price. Azure charges more per hour and requires multiple services (Speech-to-Text + Translator + Custom Speech) for the same functionality.

Takeaway

Soniox costs 2–5x less than Azure, with all features included in one API. At scale, that means saving thousands while reducing integration overhead.

Soniox bills per token, which works out to the effective hourly rates above for typical speech.
Azure pricing varies by region, model, and usage tier. Translation via Azure Translator is billed separately, and Custom Speech may add further costs.
Comparisons use publicly listed rates as of 2025. Benchmarks and pricing are based on real-world audio workloads, with each service configured for best available performance.

Why teams choose Soniox over Azure for Norwegian

Engineered for real-world accuracy in Norwegian.

Soniox delivers production-grade accuracy on messy, real-world Norwegian audio – overlapping speakers, mixed-language phrases, spelled names and numbers, and natural pauses.

"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

Azure’s accuracy drops outside clean, well-separated audio – it struggles with real Norwegian conversation dynamics and fast-paced inputs.

Shockingly precise in ultra real time.

Soniox transcribes and translates Norwegian and 60+ languages, as you speak – with token-level updates, real-time finalization, and fluent results from the first word.

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

Dag-Inge Aas,
Head of AI at Tana

Azure streams in segments, with no token-level visibility, delayed finalization, and robotic transitions that throw off real-time apps.

Understand the rhythm of real Norwegian speech

Soniox detects who’s talking, when they’ve paused, and when a sentence ends, giving structure to unscripted Norwegian conversations. Speaker separation, turn-taking, and sentence boundaries come built in.

"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

Azure lacks real-time conversational intelligence, and requires additional configuration or post-processing for diarization.

Build once in Norwegian. Deploy everywhere.

One model, one API, one call – Soniox includes language detection, speaker separation, translation, and more by default. Build once in Norwegian and reach billions of users everywhere, instantly.

Azure splits features across separate APIs like STT, Translator, and Custom Speech, each with their own costs, formats, and complexity.

Built-in domain intelligence.

Soniox understands industry-specific terminology, product phrasing, and user vocabulary in Norwegian, adapting on the fly without custom training. You can even steer translations and enforce terms that matter.

"Soniox's ability to accurately transcribe complex medical terminology means our physician-customers spend significantly less time editing. This allows them to finalize their notes faster and focus on what matters most: patient care."

Max Malyk,
Vice President at DeliverHealth

Azure requires setting up Custom Speech, adding static hints, and still lacks real-time control or guaranteed accuracy.
