The JVLMT is a 22 min- standardized voice memory test based on item-response-theory. It consists of a learning phase, a repetition phase and a testing phase. On each of 22 test trials participants are asked to recognize one of eight learned voices among 2 foils. Test scores are based on these 22 trials of varying difficulty. All stimuli contain pseudo speech utterances with similar-to-English phonetics, such that the test is applicable largely independent of participants’ native language. The individual test score of each participant will be displayed at the end of the test together with norms.
Who is eligible to use the JVLMT? The JVLMT has been developed and validated for research purposes between 2018 – 2020 by researchers of the Friedrich-Schiller University Jena, Germany, the University Hospital Jena, Germany, and the RWTH University of Aachen. The test is free to use in a non-profit manner, without the need to register. For details of the development and validation, please refer to the paper by Humble et al. (2023) and OSF (https://osf.io/cyr23/). The present online version of the test as programmed in Gorilla is provided by Ryan Jenkins and Romi Zäske (2025) in the original version with English instructions, as well as a version with German instructions.
