During the assessment of speech fluency, SLPs sometimes measure the time of the longest block. This measurement is commonly referred to as

duration

Explanation:

Duration is a term used by Speech-language pathologists (SLPs) to refer to the measurement of the time of the longest block, and it´s a variable for defining the level of severity of stuttering that a person has.

For example, the Stuttering Severity Instrument (SSI) is an evaluation tool of the severity level, which analyses the parameters of frequency, duration, and physical concomitants.
