Type-Token Ratio Curve between Digital Conditions and Speech Types

The average frequency of unique words (types) in relation to the frequency of all words (tokens) in random samples of words is depicted between (A) conditions (face-to-face vs. video chat), where the type-token ratio (TTR) curve diverges at the total number of 200 words, and (B) speech types (contingent vs. noncontingent), where the TTR curve diverges at the total number of 300 words.
