    Notes:
    1. 2:16 The data set has 40 uhmmm lists, though a couple come from repeat individuals. This was to test if people uhmmmed consistently. This does appear to be the case but I didn't have enough people to conclusively say so, so I didn't mention it. Moreover, as I discuss later in the video, not all of the people are science educators - for example at least two are politicians, which was to test if training reduced uhmming.
    2. 8:31 Surrogate analysis involves creating new data that follows a known distribution. This can be difficult in general, but in Poisson this is really easy - lets say the rate of your real data is 1 event in 10 time units, then you make a list of length say 10000, where 1000 of those are `1' and the rest are `0', and then you randomly permute that list and it will be Poisson. Next you compare the distance between the real data and the surrogate data. One common approach is using the Kolmogorov-Smirnov distance, which measures the maximum difference between the cumulative distribution functions. If the distance is small, it suggests that the real data follows the assumed distribution (e.g., Poisson), while a large distance indicates otherwise.
    3. 11:56 This is related to the previous note. Here what I mean to say is that Matt and Tom's Kolmogorov-Smirnov distances are large, so they are not likely to be Poisson. Pretty much everyone bellow Matt and Tom have small KS distances and so they are statistically likely to be Poisson. This is true even if that person is not on the line, and suggests that if we took more data they would approach the line.

    I think the Q+A bit matches up with my personal theory (without any evidence) that Tom and I have long stretches with fewer uhms because we are flipping between bits of material we have presented to audiences loads of times, with new bits we are talking about for the first time. So I guess you can tell when a speaker is being spontaneous by counting uhms; and be offended if there are none and they are just wheeling out old material.

      It's a learnable skill, though. There's a British radio show called “Just a Minute” where hesitation (among other arbitrary rules) is a rules violation, and some people are quite good. Or you could look at competitive debaters, who can (some of them, and if they want) talk indefinitely _impromptu_ without umming.

      @@niiiiiiiiiiiia Its common for public speakers to take courses on getting rid of "umms" When I took public speaking courses in college our professor said "Pauses are just as good as "umms" and "likes" for collecting yourself before continuing, but no one notices them if they are only as long as your regular "umm". It will make you appear to be more familiar with the topic" Its an older tool. So, if you notice someone not using any "umms", try to pick out short pauses instead. Its the same linguistic hesitation just no vocalization to go with it.

    Fun fact tangentially related to the topic:
    ‘Um’ Is a very much language specific mid-thought processing buffer. My parents, for reasons of their own, went to language school together as adults To learn Spanish. A point of advise they received from a teacher was that, knowing that you won’t be a native speaker quickly but you need to be passable enough communicate within a short period to later learn through persistent exposure, it was beneficial to pick up certain linguistic attitudes that essentially amount to little flags that point to - in this case - Spanish. One of those little modified behaviors was to replace ‘um’ and its friends with the Spanish appropriate ‘eh’ and crew.
    The teacher went on to roughly explain the idea that by ‘um’ing in the language you are attempting to speak rather than English that people around you generally are more patient/willing to help. Psychologically you might say the person sees you less as a bumbling foreigner butchering the language and more of a student who is a bit above their head but dutifully trying their best.

      @@kai_fatallysapphic this is largely the case because different languages have different systems of sounds and may land on a different "neutral" mouth position, neutral in the sense that it is a midpoint between all vowels. for Spanish, it happens to be 'eh' (/e/); for English, 'uh' (/ə/). this is a great clue for fluency (or passing fluency) because getting used to this position basically trains your brain to shift your entire vowel space to the target language.

    This is a great example of why interdisciplinary interaction is so essential to science!
    My dad's a speech pathologist, and as a kid I had a bad stutter. A lot of the problem was actually that I _didn't_ um. So when I'd reach a "bridge" between thoughts, where I needed to connect two ideas together (which might have different familiarity levels), instead of filling my lag time with filler words (um, er, ah, like, so, etc) my brain would grab onto my previous secure point--the last word I said--and repeat it until the connective pathway was established.
    Like another comment mentioned, this is part of why the rate of 'um' is higher in those who speak quickly: We're covering more ground faster, so the brain has to take more beats to connect ideas. 'Um' becomes like every other words: We use more of them.
    It's also why people who _think_ quickly--or slowly, too--say um more often. Thoughts grow out of sync with words, and we pause to realign things.
    As you can probably guess, my 'why' phase lasted about 8 years, and my dad ended up explaining probably a quarter of his graduate program to me in that time. A fascinating blend of linguistics, physiology, psychology, physics, and more!

  • @evilandrzej
    @evilandrzej 11 місяців тому +4407

    So-called "hesitation phenomena" are actually really important in language. "Um", "er", etc. are examples of "filled pauses" which serve various purposes in speech. They can signal to the listener that you're about to use an unusual word or express a complex idea and that they need to pay attention, or that you're about to correct something you've just said. When people learn a new language their rate of filled pauses *increases* as they become more fluent, until eventually it settles to a lower stable level. Teaching second-language learners to mimic natural filled pauses can make them sound much more fluent. Filled pauses also help toddlers learn language, and there's evidence that toddlers use the filled pauses in speech to predict the speaker's next word. Hong Zhang's (U. Penn) dissertation "The Distribution Of Disfluencies In Spontaneous Speech: Empirical Observations And Theoretical Implications" is great and definitely worth a read!

    The most interesting thing to me about uhm/erm/umm/etc. is that it's such a great example of the schwa.
    The phonetic sound ə ("schwa") is the default sound that humans make. If you just open your mouth and pass air over your vocal chords, you say "ə".
    Because of that it's the most common sound in almost every language. Three of the four most common English words are "the" ("ðə"), "of" ("əv"), and "a" (just "ə"). The first words of most babies are "məmə"/"dədə"/"pəpə".
    When I learned about ə I saw it everywhere. Pronouncing words with schwas in place of other vowels is what "mumbling" is. The pitch that is a schwa for a child is the same as the "e" of a grown man, but our brains just account for that.
    But the coolest thing, to me, is that it's our sound for holding attention. If you were developing morse code or any other form of communication from scratch you would inevitably need to find a way to tell the listener "I'm done talking, it's your turn". In morse code it's ▄ ▄▄▄ ▄ ▄▄▄ ▄ , in radio it's "over", in http it's . In English it's silence, so instead we have a signal that means "I'm still talking, it's not your turn yet", and it's exactly what you would expect it might be.
    əəəəəəəəəəəəə...
    Kind of elegant, really.

      To be fair in my languange (italian), the schwa sound isn't very frequent (i believe but i might be so wrong), but it's used like in english to uhm etc.

      This is not the same in most of the world's languages and portraying it as the "default sound" is disingenuous. In *English* it is the most commonly used sound, but that is not persistent across all languages. If you want a more common open vowel, /a/ is much more common in world languages, being attested in 86% of the world's languages (versus the 22% in which /ə/ is used, mostly in European and South Asian languages).

    My instinctive explanation for why people like Tom Scott have lower averages and higher variations is that during their presentations they go into scripted bouts, a groove where they are explaining something and where the next sentence to say is obvious and comes quickly. And they are very skilled in executing these. But then, in between these sections, when transitioning between segments, or maybe if soemthing else broke their rythm, they revert back to a more natural average like normal people. thus the variation.

    I don't remember where I learned it, but the presence of 'uhm's can actually improve the listeners' experience. It's punctuation. Punctuation increases comprehensibility. It can draw attention.

      For me as a listener, the impact of an uhm depends entirely on why the speaker just uhm'ed. If indeed they're changing mental tracks or need to think over a question during Q&A, then it can help, yes.
      However, if they're the type of speaker to uhm every single time their brain has to buffer for even a moment, then the uhm is more like noise to my brain, and I have to actively filter out that noise so that I can actually parse their sentence (but that might be an issue with me as a listener). I think the Loruhm Ipsuhm example in this video is the perfect example of this. This brain-buffering type of uhm may be exclusive to casual or inexperienced speakers, but I'd say that the distinction is still important to mention.

Awkward random silences would not help. In a way Ummms are respectful. People can rest their brains for a second and wait patiently rather than wait awkwardly wondering why they are silent and if they have anything else to say.

      When Tom goes "uhm", the audience knows he's going to get to the interesting bits. I think their use in language is to communicate "I am choosing my words, please pay attention". And for experienced speakers, they can prime listeners to pay attention. While inexperienced speakers are inconsistent with it, and might be grating/tiring the listeners attention.

      ​@@michaw7408 nothing habitual is absolutely meaningless. Why would every human waste energy on something meaningless? You could argue the subjective value of the meaning but to assert 0 value is outright silly. (Well, perhaps you spoke absolutely in effort to incite a corrected response providing you with the answer, which isn't silly after all.)
      Personally though, I get forced to "uhm" a lot more than I innately would during pauses. For example, my father is always seemingly caught off-guard when he hears a silent pause. He will interrupt what I'm about to say, just to question my unfinished thought. (Like, "if you'd just shut up and let me finish!..") If I don't fill that void with a predictable noise, then he will. A simple 'uhm' lets him know I'm still forming the sentence. Whether that's purely a condition of avoiding confusion, through losing some hearing as he ages, is harder to say. It happens with people of all ages though. I believe it's just nurtured/conditioned in your specific environment.
      I'm also quite detailed and long-winded, so I get interrupted consistently the moment I hesitate, by nearly everyone I speak to.
      I agree with other comments as well, 'uhms' can be scripted for emphasis, rhetoric, or other metacommunication.
      In practice, language is rarely literal. People, and therefore language is far too emotional in daily use. Close enough to their intentions, is close enough for most.

      @michaw7408 if the speaker is attempting to sound more casual, it would make sense to insert a few ums and uhs to make it sound natural and more like a regular conversation. I kind of doubt he would need to do that since going unscripted is likely going to lead to the same result with less effort, though. It would only be necessary for someone who is hyper aware of what they're saying and never ums normally

    My reasoning is that if you missed UHMMs uniformly, then the process remains a Poisson process. However, the rate = lambda would need to increase based on the probability of missing an UHMM per time period.

    I think you've missed 2 pretty interesting trends - 1) the structured talks from experienced educators generally tended towards platooning (above the line) and 2) when you zoomed into the data at the end, both the QnA and control groups tended towards ideal/low variance random (below the line).
    My interpretation is this: the control and QnA chats represent pretty periodic Uhms, being drawn truly randomly. However, the structured talks get platoons of uhms because they "lose their groove" during a talk. Once you say uhm once in a practiced speech, you start spilling over yourself for a while until you get it back.

    • @not_David
      @not_David  11 місяців тому +9

      That was my idea for the practiced part as well. The QnA part being periodic is an interesting idea. I do genuinely wish I had more data for that segment so I could test those ideas. There is a ... game (for lack of a better word) ... called `powerpoint karaoke' where people try to make presentations on the fly to a set of random slides. I would love to collect uhmms during that especially for the professional presenters, but obviously this is much harder to do set up.

    I think a significant factor you did not account for during this is the rate of speech for every person. Adjusting for words per minute and seeing what the true frequency in terms of syllables, words and (sub) sentences is, would give much more insight into how humans actually produce their uhmms.
    Additionally using log/log plots for data with a range this small introduces bias in reading the graph. The data can appear much more linear than it actually is simply because in log plots the range of Y values for any given X value that would be appear to be linear to a human eye is greater than the true plot counterpart.

    (EDIT 2): I havn't had a chance to respond to all the answers in this discussion but learning all the different ways people uhmm in different languages has been fascinating, thank you!
    (EDIT 3): Special thanks to @skylercloud3077 (Skyler Cloud) for sitting down and time stamping all the uhmms in this video. The result was a average of 14 seconds with a variation of 17 seconds, so I'd say fairly poisson though more tests would need to be done to confirm. If you see their comment give it a big thumbs up.
    The question:
    I asked this in a community post but I didn't I didn't appriciate just how different UHMMing (or more generally `filler words') can be across languages and cultures. So 2 questions:
    1) What is a common filler word/sound in your language?
    2) If you speak more than one language, do you also switch how you UHMMM when you switch languages? (this is the one im really interested in).
    For me - english is not my first language however my two languages have essentially merged into one frankenstein language so I can't really test this on myself.

      To comment on what @fugo said: Young people in Sweden often code-switch or think in English. So much so that it's gotten its own word, "svengelska" ("Swenglish"). But I've never experienced the equivalent of what Fugo is saying-that is to say, people my age saying "uhm" instead of "ö". A more relevant example of Swenglish is saying "två fåglar med en sten", ("two birds with one stone"), instead of "två flugor i en smäll", ("two flies in one blow").
      To expand on this: Speaking Swenglish is often viewed as something negative. There are loads of "letters to the editor"-"insändare" if you want to look them up-about this. So naturally, I think saying "Uhm" instead of "ö" would be getting coverage. However, I've never even heard of it, not from DN or Aftonbladet, Expressen or Göteborgs-Posten. This also points at people not saying "uhm" instead of "ö".
      If it doesn't happen in Swedish, I wonder why it happens in Turkish. Although I think the sample size is way too small to draw a conclusion from our comments.

      @@Pulstar232 I don't have any particular channels I watch for that specifically, or rather if there was a video I watched regarding it, it was just from googling and watching the first thing that came up. Its really just about taking cues from other media. For example, I really like watching Marques Brownlee (akak. MKBHD) because his team makes some really smooth animations and transitions, and then it was just a matter of sitting down and really working with animation curves until it felt right (animation curves are the things that set the timing of an animation and they are typically found in most animation software I believe, it is not a blender thing). But it can be anything - I actually find commericals during ads to be extremely good for inspiration for eye catching colors/movement/etc.
      Keep in mind a lot of it is practice and refinment as well. If you watch my earlier videos (especially my first) you'll see the animation is very stiff. But you have to start somewhere and get the basics down and then work up. If you watched my videos in order my hope would be you progressively see an increase in smoothness or punchiness as I learned to incorperate those higher-order things on top of the basics as i went along.

Around high school sophomore year, I found myself intentionally adding "uhh" and "uhm" into my speech at times. A good friend noticed this and pointed it out and it's stuck with me as something I notice ever since. I do it around people I don't know as well and in tense situations. I assume it's to make myself appear more fallible or relatable? Not entirely sure.

    This is awesome! The cluster of infrequent "uhmm"-ers is a nice example of overdispersion. So, they may not be Poisson, but maybe they are quasi-Poisson :-) That could be something to explore! Maybe too math-heavy though?
    It's not easy to work in math when your target audience includes people who have disliked probability in the past-- I think you did a nice job. Also, your video follows most of the American Statistical Association's GAISE recommendations that would apply to a UA-cam video! Since you focus mostly on one variable (uhmm count), I wouldn't say it "gives students experience with multivariable thinking" (the Q/A breakout sort of gets at this-- second variable is "whether or not the um happened during a Q/A", but it seems like that maybe came from a different data set?)
    On the multivariable note, here's one idea for what to do with the data, though it would require more work since it involves collecting more data: it would be interesting to explore Poisson regression where your response variable is the uhm count and the explanatory variable(s) could be anything that might affect someone's propensity to uhm. Maybe audience size, percentage of empty chairs, total hours spent public speaking (or a proxy, like for youtubers maybe their previous video count or total run time).
    I would also be curious if other filler words ("so", "like") give us the Poisson distribution? Those would be a bit harder to quantify I assume since "uhmm" is not a word but "so" can be a planned part of a sentence ("the points are distributed like so" vs. "So, if we look at the distribution..." could just be "If we look at the distribution"...I do that one a lot 😅). If you're able to get the data you could consider a marked point pattern in time, where the mark is the specific filler word used.
    Thanks so much for making this video!!

      @danieldemski2499 my head cannon is that not many drawfee fans would watch this kind of content so we're just built different. We got art in our hearts and maths in our brains

    The methodology at the beginning is very similar to how my STEM teacher in high school would get us to stop using filler words.
    Everytime after the first usage of a filler word during our presentations, he would mark it as a note and at the end, we lost one point off the grade for each filler used. It hurt, but I quickly stopped using filler words and it truly helped me understand what I was explaining to everyone else.

      Its interesting to me how I've seen a couple of commenters saying the same thing but my teachers never did that, kinda wish they had haha
