<h3>How is language proficiency measured?</h3>
Proficiency is judged in terms of receptive and expressive language skills, grammar, vocabulary, semantics, and other language abilities. Language competency is divided into four areas: reading, writing, speaking, and listening.
"Speech rate" and "utterance length" are two of the most dependable criteria. Speech rate is defined as the amount of effective language produced over time, for example, how many syllables per minute. Utterance duration is the average amount of speech you can generate between disfluencies (e.g. a pause or hesitation).
