Why enterprises choose Speechmatics over AWS

Accuracy

Accuracy on the audio that actually matters

Your users don't speak in quiet studios. Speechmatics' Ursa 2 model is trained on over a million hours of noisy, accented, real-world audio. [VERIFY: head-to-head accuracy/G2 scores vs Amazon Transcribe] When your pipeline hits Scottish accents over a bad VoIP line, that gap matters.

Deployment Flexibility

On-prem, on-device, air-gapped

Speechmatics offers mature on-premises, on-device, and air-gapped deployment. Amazon Transcribe runs only as a cloud service inside AWS regions — with no on-device or air-gapped option, limiting choices for regulated industries.

No Lock-In

Cloud-agnostic by design

Speechmatics runs wherever you do — any cloud, your own infrastructure, or fully offline. Amazon Transcribe ties your speech pipeline to the AWS ecosystem, making multi-cloud and exit strategies harder. [VERIFY: pricing comparison]

Speechmatics is trained on difficult audio: call-centre noise, accented speech, VoIP, and crosstalk. [VERIFY: accuracy benchmark vs Amazon Transcribe]

Deployment flexibility

On-premises, on-device, and air-gapped deployment for regulated and data-sensitive workloads — options Amazon Transcribe's cloud-only service does not offer.

No ecosystem lock-in

Run Speechmatics on any cloud or fully offline, instead of tying your speech stack to a single hyperscaler.

Simple, predictable pricing

Straightforward all-inclusive per-hour pricing. [VERIFY: Amazon Transcribe tiered pricing and feature add-on costs]

Dedicated enterprise support

Direct access to speech specialists and enterprise SLAs, rather than general-purpose cloud support tiers. [VERIFY: AWS support tier details]

Built for voice, not bolted on

Speech-to-text is our entire focus — every release advances accuracy, diarisation, and real-time performance, not one service among hundreds.
