Investigating 'um' and 'uh' and other hesitation phenomena

This site is devoted to disseminating information about filled pauses and related phenomena in communication. Here, you can find academic information about these topics, musings on this and sundry other things as well as links to various resources that I've created that may elucidate why, how, and when people say 'um'.

Info about the Disfluency in Spontaneous Speech workshops

What's the difference between real-time and latent fluency detection?

I have been pushing the uniqueness of the Fluidity application as its capability to detect fluency features in real-time, maintain a constantly updating set of measurements, and adapt the operation of the application accordingly. This is in contrast to most applications in which fluency measurement takes place on a completed speech sample; that is, after the speaker has finished. Besides the technical differences between these two, is there any practical difference either to speakers or to listeners/computers related to this?...

Disfluencies in face-to-face versus video-mediated communication

There is some research to show that the use of filled pauses is different in face-to-face versus telephone conversations (cf., high rate of FPs in Switchboard versus low rate in Santa Barbara Corpus). In particular, speakers tend to use more filled pauses on the telephone. It has been hypothesized that the reason for this is that because the visual element is lost, speakers are more apt to try to manage conversational turns through additional vocal elements and thus, they might use filled pauses more often to "hold" their conversational turn. (Leaving aside the debatable question of whether speakers actually use filled pauses in that way or not.) A good question to ask now that video conferencing is becoming a ubiquitous form of communication is whether the use of disfluencies in video-mediated communication differ from those in regular face-to-face communication....

Virtual trip 2 Sweden 4 NLP4CALL

Well, the Covid-19 situation continues, and conference organizers are gradually adapting and finding ways to hold productive events online. I participated in another even this past week which was quite well-run and an interesting conference, to boot. Though unfortunately, I didn't give any presentation of my own. The event was the Swedish Language Technology Conference (SLTC) with a workshop on the side called Natural Language Processing for Computer-assisted Language Learning (NLP4CALL). While the SLTC event was fairly interesting, my main focus was NLP4CALL. All the presentations were very interesting, but not directly about filled pauses or hesitation phenomena. Yet, they inspired some ideas of my own, which is what a good conference should do....
