Which category of speech testing involves closed set measures?

Threshold measures primarily focus on determining the lowest level at which an individual can detect sounds or speech stimuli. These measures typically use an open-set format where the test subject is presented with stimuli that they can respond to freely, rather than being limited to a set of predetermined options.

In contrast, recognition measures encompass closed-set testing, where a test taker is presented with a fixed number of options to choose from. This format allows for a more controlled assessment of a person’s ability to recognize and identify speech signals within a limited range.

Closed-set measures are particularly useful in contexts where the test administrator wants to assess specific auditory processing capabilities, such as phoneme or word recognition, without the variability that comes from open-set tasks. Examples include using picture cards or word lists, where the subjects choose answers from a defined set, thereby making it easier to evaluate their recognition performance.

Therefore, recognition measures are the category that most accurately encompasses closed set measures, as they assess the ability to identify speech when presented with a limited number of choices.
