I've heard professional speakers utterly hampered by "ums", nonsensical random streams of thought, etc., to the point I've had to leave, switch stations/channels, or stop listening. Rare, but memorable.
The exception might be made for someone whose material or story is so utterly compelling that you're willing to overlook such idiosyncrasies. However, most of us are not such special snowflakes.
