Read vs. spontaneous speech
Across the many disciplines that analyze language, there's surprisingly little focus on the properties of natural, spontaneous speech, as opposed to read (or memorized and performed) speech. But of course that dichotomy is an oversimplification — there are many linguistic registers, many ways to read each of the many styles of text, and even more individual, social, and contextual factors influencing spontaneous speech.
So one place to start is events where the same speaker, addressing the same audience for the same purposes, both reads a passage and answers questions — in such cases, at least the speaker and the context are controlled. In "Fluent 'disfluencies' again", 9/3/2022, I looked at the question-answering part of such an event, a press briefing by the U.S. Department of Defense Press Secretary, Brigadier General Patrick S. Ryder. At least, I looked at one small aspect of some of his answers, namely the distribution of certain kinds of disfluencies interpolations.
The focus of this morning's Breakfast Experiment™ will be one of Ryder's more recent press briefings, comparing the introduction (where he reads prepared text) to the first of his answers to subsequent press questions. I'll look at (aspects of) the properties of speech segments and silence segments, as well the statistics of local inter-syllable durations. For both of those features, fully-automatic analysis techniques allow research at scale, though this morning's data sample is small.
I'll also take a short comparative peek at his filled pauses and rapid word-repetitions in the two passages.
