Voice input facilitates documentation - A hackathon topic

Voice input makes it possible to intuitively record food eaten and drunk without having to look at a device or tap. Instead of laboriously entering everything by hand, users can simply record their meals and snacks by voice command. This approach can lower the inhibition threshold and encourage users to continuously document their eating habits. This saves time and encourages regular documentation.

How do they together contribute to designing digital products in such a way that they are not only beautiful to look at, but also offer a smooth and satisfying user experience? In this blog article, I would like to differentiate between the terms and show how they interact.
