Which aspect is NOT assessed by a speech audiometry test?

The focus of speech audiometry tests primarily lies in evaluating how well individuals can understand and process spoken language, typically under various conditions and at different sound levels. This includes measuring the ability to understand speech in noisy environments, repeating words at various volumes to assess clarity and recognition, and determining the clarity of hearing individual phonemes, which are the smallest units of sound in speech.

However, the ability to read lips is not something that speech audiometry tests evaluate. Lip reading relies on visual cues from a speaker's mouth and facial expressions, rather than auditory processing abilities, which are the basis of the tests being described. Therefore, it does not fall within the parameters of speech audiometry, which assesses auditory perception rather than visual comprehension of speech.
