Or at least another pattern of its usage.
According to Herbert Clark and Jean Fox Tree, "Using uh and um in spontaneous speaking" (Cognition 2002),
"[S]peakers use uh and um to announce that they are initiating what they expect to be a minor (uh), or major (um), delay in speaking. Speakers can use these announcements in turn to implicate, for example, that they are searching for a word, are deciding what to say next, want to keep the floor, or want to cede the floor."
As they note, the actual patterns of pause and filler durations are somewhat complicated — a larger-scale empirical survey can be found here. Extending many LLOG posts, Wieling et al. (2016) document a historical change in relative UM/UH frequencies across various Germanic languages, associated with sociolinguistic dimensions of gender, age, education, and so on. And there are well-established individual patterns of usage, as well as evidence for conversational accommodation.
But listening to a recent YouTube interview, I noticed a somewhat different pattern. An extremely fluent speaker uses a very brief "uh" as the first syllable in many of his prosodic phrases, following a brief inter-phase silence, with no post-UH silence. There's no indication that he is "searching for a word, deciding what to say next, wants to keep the floor, or wants to cede the floor", and I noticed no other filled pauses on his side of the interview. So for this speaker, phrase-initial UH seems to have become something of a habit. It's unclear what his UH-or-not choice signals, if anything.
