Developement of the scales Response Behavior, Response Quality, and Comprehensibility for voice assistants is described in Klein, Schrepp & Thomaschewski (2020). Development and first validation of the scale Clarity is described in Klein, Hinderks, Schrepp & Thomaschewski (2020).

The development of the UEQ+ are described in a number of scientific papers.
The UEQ+ is currently available in more than 20 languages. When new scales are added to the UEQ+ framework it will require some time until translations are available. Thus, these new scales may not be available in all translations. Only the German and English templates will always contain all scales.
The following translations were provided by Henning Brau.
