NOZ Mediengruppe & BotTalk Case Study

NOZ Audio App

NOZ Mediengruppe has been pioneering an audio strategy since 2019. Integrating BotTalk into their news websites and apps opened a new category in the news business industry.

NOZ Mediengruppe at a Glance:

  • 50 media companies with a focus on news
  • 60 locations all over Germany
  • Publish 20,000 articles per month
  • Generate over 20 hours of audio articles daily


Using BotTalk at the core of the news products, NOZ cracked several challenges:

  • Adapting to changing user behavior: They recognized that content consumption on the internet was primarily shifting towards audio before video and text. As a publisher primarily focused on text-based content, NOZ wanted to address the new user behavior and make their content audible.
  • Cost and scalability of audio content production: NOZ published approximately 20,000 articles per month, and hiring human speakers to voice all the articles would have been impractical and expensive. They needed a solution that could automate the process of converting text-based articles into spoken content at scale.
  • Quality control and customization of synthesized voices: Initially, NOZ experimented with existing Text-To-Speech (TTS) technologies but faced challenges in controlling the quality and customization of the synthesized voices. They needed a solution that allowed them to adjust pronunciation rules, build a dictionary for specialized terms, and improve the overall audio quality.
  • Integration into existing products: NOZ wanted to integrate audio content into their web portals, mobile app, and other digital products that already had an established user base. They needed a solution that seamlessly integrated with their existing infrastructure and provided a user-friendly interface for managing and delivering audio content.

By addressing these problems, NOZ Digital aimed to stay ahead of evolving user preferences, automate audio content production, ensure quality control, and create a comprehensive audio offering for their users.

Key capabilities

NOZ tested several companies and evaluated an approach to build a text-to-speech solution in-house. But after thorough consideration, they selected BotTalk as the primary solution for audio article creation using text-to-speech technology.

"Our goal was to create a 360-degree audio offering in Germany and Europe, where users could genuinely choose between reading and listening. To achieve that, we needed high-quality audio content that catered to the users' informational needs.", explains Patrick Körting, Head of Audio at NOZ.

Focus on News Publishing

Other Text-To-Speech providers may focus on general voice synthesis, but BotTalk understands the specific challenges publishers face. They recognize the importance of preserving context, handling specialized terms, and maintaining the integrity of the content within the publishing landscape.

"BotTalk offers a way to have quality under control and continually enhance it. We had internally estimated the cost of building everything ourselves and, considering time-to-market, it just didn't make sense. It's key to have someone like BotTalk, a sparring partner who consistently shows where we can improve. That's the crucial point for me", explains Patrick Körting, Head of Audio at NOZ.

Superb Audio Quality

"What impressed me in our initial conversations was that BotTalk team knew about certain aspects and adjustments that I wasn't even aware of. It goes beyond selecting a voice; it's about fine-tuning the pitch, volume, and other factors. BotTalk strongly focused on improving the service, which was quite rare. That's why I dove into this topic and realized someone nerdier than me has delved deep into it and can provide even more levers for improvement than I was aware of."


BotTalk simplified the integration process for us. We had a solid foundation with their technology, and we could focus on refining and enhancing the user experience. It was crucial to have a partner who understood the publishing industry and had a clear vision of how to improve the Text-To-Speech service for publishers

New Business Opportunities

Patrick Körting: "Text-To-Speech technology has the potential to transform news publishing into something akin to a radio station. With the ability to deliver a constant stream of audible content, publishers can provide a comprehensive audio experience that rivals traditional radio, offering news updates, informative pieces, and engaging storytelling. It's a new frontier where publishers can captivate their audience through spoken word, creating a unique blend of news and entertainment in a format that resonates with the evolving habits of modern listeners."
