We are a speech technology company building machine learning technology that enables us to generate credible speech that is indistinguishable from real human voices, from text. We aim to revolutionize the way brands and individuals interact with technology through voice. Our cutting-edge AI creates entirely unique, emotionally resonant voices from scratch, tailored to your exact preferences.

Imagine Siri, but with a voice that captures Apple’s essence. Or Alexa, with a voice that embodies Amazon’s brand. That’s the power of DAISYS.

We’re not just cloning voices or using generic samples. We’re pushing the boundaries of speech technology, crafting voices that forge deep, personal connections.

And we’re doing it all with an unwavering commitment to ethics and respect for privacy. No cloning, no unauthorized use of data – just groundbreaking innovation that’s transforming the future of human-tech interaction.


Barnier Geerling

CEO & Founder

I’m a voice-over artist and sound engineer. I own a recording studio and am founder of the largest Dutch educational institute for voice-overs, Stemacteren.nl. As a ‘nerd’ and technician I have a broad knowledge of the exploitation of voice and audio technology in new applications.

I’m captivated by questions like “How can humans and technology strengthen, augment and improve each other?” and “Will computers ever be able to think, feel, and act just like us?” I enjoy composing music and making pastries in my spare time.

Joost Broekens

Outside of the tech world, you’ll find me in the outdoors, either camping or hiking in the mountains. I make it a weekly ritual to catch a movie at the cinema, and every year, I participate in the Dutch Jigsaw Puzzle Championship, though I never made it to the finals so far.



AI Shakespeare Unleashes Ethical Text-to-Speech Magic: Personalized, Shakespearean Plays Come to Life with Novel AI Voices

This groundbreaking project demonstrates the company’s commitment to ethical TTS technology and its potential to revolutionize the future of content.

AI Shakespeare offers a unique experience, allowing users to type in any prompt and instantly generate a Shakespearean-style play. What sets this project apart is the use of novel voice creation technology, a TTS solution that generates entirely new, original voices rather than relying on voice cloning or deepfakes.

This approach reflects DAISYS.ai’s dedication to ethical AI, as it avoids the potential misuse of cloning voices and respects the rights of voice professionals. The company’s novel TTS technology not only offers a fresh take on speech synthesis but also represents a significant step towards more targeted, individualized content.

“Our mission with AI Shakespeare is to showcase how the future of content is rapidly shifting from a static, one-size-fits-all model to a more dynamic, personalized experience,” said Barnier Geerling, CEO of DAISYS.ai. “Imagine a future where content changes in real time, adapting to your surroundings or moods. Traditional voice recordings simply can’t accommodate this level of customization, but our novel voices, which can be altered in real time, are uniquely suited for this purpose.”

As the demand for personalized content continues to grow, DAISYS.ai’s TTS technology positions AI Shakespeare at the forefront of this emerging market. Users can revel in the hilarity of AI-generated content that sounds convincingly real. AI Shakespeare leverages the power of GPT-4 technology to generate scripts based on user prompts, and seamlessly couples this with its novel voice speech technology to deliver live, AI-generated content that demonstrates the immense potential of this cutting-edge innovation.

Dutch AI start-up creates breakthrough in voice technology
‘New voices that sound like real people’

Worldwide breakthrough
‘This is a huge breakthrough. Up until now, naturally sounding voices were always deepfake, based on audio data of professional speakers. But deepfakes in text-to-speech for many reasons aren’t usable. One of those reasons is that not everyone wishes to lend out their voice without having control about what is being said with it. With this technology, as the first company in the world, we are able to create new voices that sound like real people,’ Barnier Geerling, CEO of DAISYS explains. ‘In addition,’ Geerling says, ‘this technology makes it easier and faster to apply speech-steered technology. The market potential is enormous, think of audio-visual media using voice-overs, or ‘talking’ cars, robots, or appliances. For manufacturers this means the possibility to integrate realistic speech in their products becomes much easier and more efficient.’

Artificial Intelligence
During the past year and a half, the start-up from Leiden has worked on its technology with a small international team of Artificial Intelligence (AI) developers. ‘We’ve made several important adjustments to the existing basic technology. In addition, we had to cleverly ‘train’ our models, using the right balance of speech data from different speakers. Because of this we’ve managed to generate new, naturally sounding voices that can be real-time adjusted by means of gender, pitch, power and speed.’ Dr.ir Joost Broekens, Chief Technology Officer at DAISYS, explains.

Voice technology; ever more important
The new voice technology is suitable for all online and offline surroundings where the human voice is used, like traditional media, smart devices, games, robots, speech assistants and public announcement systems. Geerling: ‘Credible voice technology is becoming ever more important. Nowadays, everything has a voice: your phone, your car, even your coffee machine. Imagine being able to adjust that voice to your preference. That future is now within reach.’

Audio Samples

Listen to an example of our generative voices here. For this sample we just typed in text. No deepfakes were hurt in the making of this.
