Munich, October 2025 – CBTL is setting a new benchmark in secure speech technology by integrating ReadSpeaker’s speechServer into its EVOLUTION³ production platform. This collaboration allows organisations in industry and defence to produce natural-sounding audio directly within EVOLUTION³ — entirely on-premises, with no external processing required. This ensures that sensitive data remains within the company’s IT infrastructure, guaranteeing complete data sovereignty and compliance in over 75 languages.
This development makes EVOLUTION³ an even more powerful production environment for complex multimedia learning content. Teams can produce multilingual and accessible audio as part of their workflow, maintaining consistency and reducing time to delivery. Seamless integration of the text-to-speech engine ensures consistent pronunciation and high-quality voice output, while simplifying localisation and maintaining full control over data, processes and quality standards.


Secure Automation for Scalable Training
Security and compliance are of the utmost importance in defence, government and other regulated sectors. By integrating ReadSpeaker technology into EVOLUTION³, CBTL can create professional voiceovers entirely within a secure environment. This prevents data exposure, accelerates production, and enhances didactic quality by ensuring consistent terminology and pronunciation across all languages.
The integration brings automation and inclusivity together, allowing authors to easily adjust parameters such as speed or intonation, while built-in accessibility features ensure that everyone can use the software. The result is a reliable, scalable and secure production process that shortens development cycles and minimises coordination effort.
Secure and Seamless Expansion of the EVOLUTION³ Production Platform
The new module extends the automation capabilities of EVOLUTION³, making speech generation an integral part of the authoring workflow. Audio can now be generated, edited and reviewed in just a few simple steps, with no need for external tools or exports.
