Soniox vs Google
for Indonesian speech-to-text

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

Developers choose Soniox for accuracy that scales in Indonesian

Indonesian is spoken by 270 million people worldwide — primarily in Indonesia, with speakers around the world. Soniox delivers production-ready transcription and translation for Indonesian, handling regional accents, code-switching, and real-world audio conditions.

Google Cloud Speech-to-Text supports 100+ languages, including Indonesian, 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.

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.

Why teams choose Soniox over Google for Indonesian

Native fluency in real-world Indonesian.

Soniox delivers native-speaker level accuracy in Indonesian and 60+ languages, including mixed-language phrases, regional accents, and spelled names and codes – even in noisy, unscripted conversations. No clean audio or tagging required. It just works.

"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

Google supports 100+ languages but struggles with real-world inputs: overlapping speakers, dialects, accents, and language shifts mid-sentence.

Transcribe and translate Indonesian at the speed of speech.

Soniox captures every word the moment it’s spoken, with token-level updates that appear instantly. Captions stay in sync. Assistants respond in real time. Conversations never fall behind.

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

Dag-Inge Aas,
Head of AI at Tana

Google streams in laggy chunks, causing transcripts to jump and delay. No token-level updates. No real-time finalization. No intelligent endpoint detection.

Understand conversations, not just words.

Soniox separates speakers, detects sentence boundaries, and structures transcripts like natural conversation — even in Indonesian mixed with other languages. Every voice gets heard and understood.

"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

Google lacks real-time diarization, and doesn’t natively support turn-taking or sentence boundary detection in real time.

One model that works everywhere.

Transcribe, translate, and understand Indonesian speech, all from a single API call. Soniox handles speaker separation, language detection, and any-to-any translation out of the box. Build in Indonesian, deploy globally with no tuning or switching endpoints.

Google splits features across multiple APIs and requires upfront language selection. No auto-detect, no unified endpoint, just fragmentation.

Built-in domain intelligence.

Soniox understands technical terms, industry jargon, and custom phrasing in Indonesian, adapting on the fly. You can even enforce terminology and steer translations to match your product and audience.

"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

Google doesn’t support real-time domain adaptation or user-guided terminology control.

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.

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.
