Estimates how much spoken content users process per line during screen-reader playback.
Accounts for punctuation concentration that can increase cognitive overhead in spoken output.
Adjusts ideal line-length targets for prose, instructional, technical, or legal content patterns.
For a 78-character line with moderate punctuation, the model typically returns a borderline-to-optimal auditory pacing score depending on content type.
