  • Your organisation has no EU data-residency constraints
  • Migration costs outweigh the jurisdiction benefits for now

Why choose Speechmatics over AssemblyAI?

The decisive argument is data jurisdiction. AssemblyAI is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

Speechmatics removes that overhead. As a United Kingdom-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.

What's the main difference between Speechmatics and AssemblyAI?
The biggest difference is jurisdiction: Speechmatics is based in United Kingdom and operates under GDPR and EU data-protection law, while AssemblyAI is headquartered in US and may transfer data outside the EU. For regulated industries or organisations following Schrems II guidance, this difference is decisive.
Is Speechmatics GDPR-compliant?
