Why enterprises choose Speechmatics over AWS
Why enterprises choose Speechmatics over AWS
Built for real-world audio
Speechmatics is built for real-world conditions — noisy backgrounds, diverse accents, and challenging audio — with a global, accent-inclusive approach to building every language, not just clean recordings. It holds a 4.8/5 G2 rating versus Amazon Transcribe’s 3.9/5 (Spring 2026).
One model, every accent
Speechmatics uses 55+ production-proven languages, each with a single inclusive model that recognizes every regional variant. Amazon Transcribe needs a separate model per dialect — one for US English, one for UK English, one for Welsh, and so on.
Independent — and built only for speech
Speechmatics’ only business is speech. You get true on-premises deployment with no AWS lock-in, freedom to run in any cloud or none, and dedicated Customer Success and Sales Engineers for enterprise — not a ticket queue behind thousands of other services.

Accuracy in real-world conditions
Speechmatics is built for real-world audio — noisy backgrounds, diverse accents, and challenging conditions. It holds a 4.8/5 G2 rating versus Amazon Transcribe’s 3.9/5, with a global, accent-inclusive approach to every language.
Single model, every accent
Amazon Transcribe needs a separate model per dialect — US, UK, Welsh, Irish English and beyond. One Speechmatics model captures the root language and all its global variants, in one.
Global medical models
Speechmatics offers dedicated medical uplift models in English, French, German, Spanish, and Arabic-English, available globally. AWS HealthScribe and Transcribe Medical are US English only — a hard stop for international healthcare.
Best-in-class real-time diarization
Speechmatics delivers reliable real-time speaker diarization, with channel diarization also available. Amazon Transcribe’s speaker detection is a frequent customer pain point, with diarization errors a common reason teams switch.
A specialist, not a hyperscaler
Speechmatics runs in true on-premises containers (CPU-capable, air-gapped) with no AWS lock-in, plus dedicated Customer Success and Sales Engineers. Speech is our entire business, not one of thousands of services.
Lower entry cost & simpler pricing
Speechmatics starts from $0.129/hr (Melia batch). Amazon Transcribe starts at $1.44/hr, the same for real-time and batch, with volume discounts only kicking in above 250K minutes a month — a high barrier for most teams.

Frequently Asked Questions: Speechmatics vs AWS
In real-world conditions, yes. Speechmatics is built for noisy audio and diverse accents, and holds a 4.8/5 G2 rating versus Amazon Transcribe’s 3.9/5 (Spring 2026). Where general-purpose cloud models degrade with background noise and accents, Speechmatics takes a global, accent-inclusive approach to building every language.
Speechmatics uses a single inclusive model per language that recognizes every regional variant — UK, Irish, Welsh, Scottish, Indian, Australian and Singaporean English, all in one model. Amazon Transcribe typically requires a separate model per dialect (one for US English, one for UK English, one for Welsh English, and so on), which adds complexity for global operations.
No. AWS HealthScribe and Amazon Transcribe Medical support US English (en-US) only and are limited to a US region. Speechmatics offers dedicated medical uplift models across English, French, German, Spanish, and Arabic-English bilingual, available globally — a major advantage for international healthcare deployments.
Both providers price by usage. Speechmatics starts from $0.129/hr (Melia batch). Amazon Transcribe starts at $1.44/hr (Tier 1, the same for real-time and batch), and its volume discounts only begin above 250,000 minutes per month — a high barrier for most teams.
Speechmatics offers best-in-class real-time speaker diarization, with channel diarization also available. Amazon Transcribe’s speaker detection is a recurring pain point, with customers reporting frequent diarization errors. Reliable speaker separation is one of the most common reasons teams switch to Speechmatics.
Yes. Speechmatics can auto-detect multiple languages present in a single stream. Amazon Transcribe is not strong at auto-detecting when multiple languages appear in one recording, so customers often have to supply a list of expected languages as a hint.
Yes. Speechmatics offers true on-premises containers that you orchestrate and scale yourself, can run entirely on CPU infrastructure, and can be deployed offline in secure, air-gapped networks. Amazon Transcribe is primarily a cloud service with limited on-premises options.
Yes. Speechmatics offers a straightforward REST API and WebSocket interface for real-time transcription. To help you evaluate the switch, we are offering $200 in free credits with the code SWITCH200, plus hands-on migration support from our customer success team.
