Soniox vs Google
for Dutch speech-to-text

Higher accuracy, real-time features, and up to 7x lower cost than Google for Dutch transcription.

Developers choose Soniox for accuracy that scales in Dutch

Dutch is spoken by 24 million people worldwide — across Netherlands, Belgium, Suriname, and beyond. Soniox delivers production-ready transcription and translation for Dutch, handling regional accents, code-switching, and real-world audio conditions.

Google Cloud Speech-to-Text supports 100+ languages, including Dutch, and integrates with Google Cloud, but accuracy drops in noisy or overlapping speech. Streaming feels laggy, and developers often juggle multiple models or pair it with the Translation API to fill gaps. Soniox delivers higher accuracy, faster streaming, and all features in one API at up to 7x lower cost.

Top accuracy in Dutch on real-world speech

Dutch Word Error Rate 9.4% for Soniox vs 23.2% for Google (lower is better).

Streaming that feels live

Token-level updates in milliseconds, with manual finalization and endpoint detection .

Lower cost, higher value

Soniox is 2-7x cheaper than Google (~$0.10–0.12/hr vs ~$0.24–0.72/hr)

SONIOX VS GOOGLE AT A GLANCE

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

Accuracy where it counts. Speed when it matters

Accuracy you can trust.

Soniox delivers transcripts you can trust in messy, real-world Dutch audio: noisy calls, YouTube clips, or overlapping speakers.

Google lists 100+ languages, but accuracy often drops outside of clean, controlled audio.

Streaming that feels natural.

With token-level updates, Soniox keeps captions and assistants in sync. Non-final → final refinements, manual finalize, and endpoint detection give you full control for Dutch.

Google streams in larger chunks, adding lag and making transcripts jump. No token-level updates, no finalize, no endpoint detection.

One model for global speech.

Dutch transcription, translation, diarization, timestamps, and confidence – all in one model that auto-detects languages and supports mid-conversation shifts.

Google makes you pick languages and model variants up front, with no auto-detect and fragmented endpoints.

Lower cost, simpler ops.

At ~$0.10–0.12/hr, Soniox includes all features. Google costs $0.24–0.72/hr and often requires adding Translation API calls.

With Google, you pay more and manage more.

Pay 2-7x less than Google

With Soniox, everything is included in one price: transcription, streaming, diarization, translation, timestamps, and confidence. Google charges more per hour, and enhanced models cost even more.

Takeaway

Soniox costs 2–7x less than Google, while delivering higher accuracy and richer features. At enterprise scale, the savings are even clearer: over 3 years, Soniox can save companies hundreds of thousands of dollars compared to Google.


  • Soniox bills per token, which works out to the effective hourly rates above for typical speech. Google's pricing varies by model and region, and "enhanced" models cost significantly more.

Soniox: 9.4% WER vs Google: 23.2% WER (real-world Dutch audio).

2.Is Soniox cheaper than Google Speech-to-Text?arrow_downward
Yes. Soniox costs ~$0.10–0.12/hr. Google charges $0.24–0.36/hr (standard) and $0.72/hr (enhanced). That means Soniox is typically 2–7x less expensive.

3.Does Google support more languages than Soniox?arrow_downward
Google lists 100+ languages, but accuracy varies widely. Soniox supports 60+ with consistent, production-ready accuracy and any-to-any translation in one API.

4.Does Google support diarization and timestamps?arrow_downward
Yes, but Soniox provides them faster and in real time.

5.Can Soniox handle multiple languages in one stream?arrow_downward
Yes. Soniox auto-detects and supports mid-conversation shifts. Google requires you to pre-select a single language for each request.

6.Can Soniox handle multiple Dutch dialects?arrow_downward
Yes. Soniox is trained on real-world audio and supports dialects, slang, and code-switching.

7.How does Soniox streaming compare to Google's?arrow_downward
Soniox streams token-by-token in milliseconds, with non-final → final refinements, manual finalization, and endpoint detection. Google's streaming works in larger segments, which adds latency and makes transcripts "jump" or lag.

8.Do I need multiple APIs with Google?arrow_downward
Yes. With Google you often need Speech-to-Text for transcription, Translation API for multilingual support, and different model "variants" (video, phone, command & search). Soniox includes transcription, diarization, translation, timestamps, and confidence scores in one API call.

9.Does Google support two-way translation?arrow_downward
No. Google requires separate use of the Translation API, and typically handles one-way source → target. Soniox supports real-time two-way translation directly in the same stream.
