EUROPEAN VOICE AI

The only Speech-to-Speech Voice AI trained on European languages.

Structured Data Extraction

Reliable email dictation and phone number capture in local formats. IBAN validation, postcodes, VAT numbers.

Multi-Language Context Switching

Handles customers switching from German to English mid-sentence, or French callers spelling names in English.

European Names & Addresses

Correctly transcribes 'Seidengasse 123a' or "Hans-Müller-Straße". Native support for umlauts, accents, and regional name variations.

Why European voice AI training matters for platforms

When your voice AI platform serves European banks handling "Müller" transactions, insurance companies processing "Straße" addresses, or contact centers capturing IBANs and phone numbers, Speech-to-Speech model accuracy on European data isn't optional.

ENTERPRISE SECURITY

GDPR-compliant, ISO 27001 certified.

When your customers are banks, insurance companies, and government agencies, compliance isn't optional. Our Speech-to-Speech infrastructure is built for European enterprise requirements.
