CBTL and ReadSpeaker Deliver Secure Speech Technology for the Defence Sector

October 2025 – ReadSpeaker, a global leader in text-to-speech (TTS) technology, today announced a strategic collaboration with CBTL GmbH, one of Germany’s leading e-learning providers for enterprise and defence organisations.

Together, the companies have delivered a defence-grade speech solution that combines ReadSpeaker’s speechServer technology with CBTL’s flagship EVOLUTION³ (opens in a new tab) eLearning production platform.

The collaboration delivers a voice technology solution that combines lifelike, multilingual audio generation with maximum data security, designed specifically for training at scale in highly regulated environments.

Addressing a critical need

For defence and government organisations, trust and security are non-negotiable. CBTL needed a speech technology partner that could deliver high-quality, natural-sounding audio while keeping every process on-premise and all data within CBTL’s control.

By embedding ReadSpeaker directly into CBTL’s eLearning production platform “EVOLUTION³ (opens in a new tab)”, course and content creators can now generate professional-grade audio files—German, English, and dozens more languages—without leaving the platform.

The result: faster training production, improved consistency across languages, and guaranteed protection of sensitive data.

Partnership built on precision and perseverance

“The sectors we serve require absolute precision in how training materials are delivered and data is managed—both in content and in compliance,” said Sebastian Wolter, Head of Marketing, CBTL Gmbh.

 

“With ReadSpeaker, our customers tell us the audio quality is ‘completely different from normal AI voices.’ They notice the clarity, the correct pronunciation of technical vocabulary and brand names, and the confidence of knowing everything is generated securely within EVOLUTION³ (opens in a new tab). That combination is unique in the market.”

Roy Lindemann, CMO of ReadSpeaker, added:

“Our collaboration with CBTL demonstrates how secure, on-premise integration can meet the rigorous demands of the defence, industrial and automotive sector. Together, we’ve built more than a product—we’ve built trust. By combining CBTL’s experience in e-learning with ReadSpeaker’s speech technology, we are proud to deliver voices that are natural, precise, and reliable in the most security-sensitive environments.”
