Turns text into speech across 100+ voices and 40+ languages, and because it lives inside AWS it bills through the account and IAM roles you already run, which is what keeps teams there. Standard voices cost 4 dollars per million characters, neural 16 dollars and generative 30 dollars. Amazon Web Services, Inc. runs it from the US, so the CLOUD Act applies.

ReadSpeaker is headquartered in Driebergen-Rijsenburg, Utrecht, in the Netherlands, founded in 1999 and now part of Hoya Corporation. The company is ISO/IEC 27001:2022 certified, fully GDPR compliant, and provides VPAT documentation for procurement. European hosting options keep voice processing under EU jurisdiction, making ReadSpeaker a trusted choice for public sector, education, and regulated industries across the continent.
Why choose ReadSpeaker over Amazon Polly?
The decisive argument is data jurisdiction. Amazon Polly is headquartered in the United States, 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.
ReadSpeaker removes that overhead. As a Netherlands-based provider, it operates under EU 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 jurisdiction that can change the rules without warning.
