Speechmatics: sovereignty score and 8 European alternatives

Speechmatics provides speech recognition and speech synthesis through an API and SDKs, for voice AI products and enterprise applications. Its engine handles live and batch transcription in many languages, and customers can run it in the cloud, on premises or on a device, depending on their privacy needs. The contracting company is Cantab Research Limited, trading as Speechmatics, registered in England and Wales.

Speechmatics is a UK company, outside the EU and the EEA. For transfers of personal data from the EEA, its privacy policy refers to safeguards such as the EU standard contractual clauses. The policy says that data may be stored and processed outside the EEA, the UK or Switzerland, and that some third-party cloud providers use servers in the USA. The company does not state hosting locations for customer data in the EU or UK. The company describes itself as a data processor for customers under the GDPR, says it signs data processing agreements with them, and names an EU representative. Running the software on your own infrastructure keeps audio in your own environment.

Why digital sovereignty matters with Speechmatics

Speechmatics is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Speechmatics hosts data outside the EU (US, OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Speechmatics is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Speechmatics together with your other vendors and gives a total score, a heatmap and the main risk drivers.
