The waveform of those sibilants looks so cool I wanted to highlight it. There’s a LOT of turbulence and a very wide half-cycle shape. Manner

First Guess

My first guess is

-tʃ
+i
+z
+ɪ
-v

Hmm.

Revision

Since the affricate didn’t work for the first segment, I have three options: 1) it’s not really an affricate and is a sibilant. Starting with <sh> doesn’t make sense with the correct responses, so then I would be thinking about [s] instead. 2) It’s a voiced affricate and the voicing is just unclear. I also don’t think there’s any words that fit that criteria. That puts me stuck with [s]. The words that will fit then are <seizing> and <seizes>. The fifth segment really does not look like a sibilant, so the former is what I’ll go with.

My second guess is

-s
+i
+z
+ɪ
+ŋ

Huh? Okay I was confident but I need a serious backtrack. Maybe I shouldn’t have convinced myself away from the release burst at the beginning, and this is aspiration. That is consistent with the funky shape of the waveform, the release burst, and the lack of a visible voicing bar.

My third guess is

+t
+i
+z
+ɪ
+ŋ

Postmortem

I don’t know how many days I’m going to gramle and make the same mistakes. I think part of the general challenge of reading spectrograms is to know what unusual phenomena are ignorable versus which ones are really indicative of the categorical quality of the sound.

Segmentation

The segmentation here is obviously very difficult thanks to the sonorance. There are big changes in the formants, but they don’t all line up to the same points of time. I’m combining formant info with trends in the amplitude as seen in the waveform. Segmentation

Step 5: First Guess

My first guess is

-w
-oʊ
+l
+z

Okay not good but not bad.

Step 6-?: Revision

Now that I know my S4 was wrong I’m going to say that that’s an [m] based on the context. There are a few words that end in [almz], but none that start with a sonorant. Maybe there’s a weird voiced stop? I can’t see a release but I’ll try.

My second guess is

-b
-a
+l
-m
+z

Ah, there’s another approximant that can go in S4: a rhotic. I’ll go back to a reasonable approximant and back vowel for S1 and S2:

-u
+l
+z

Uh oh, not doing great. Using my word class generator again, I got these candidates:

The second word has the stress in the wrong position, so it’s out. The F1 is a little low for [i], so I’m going to go with the first option.

My fourth guess is

+ɹ
+æ
+l
+i
+z

Finally.

Step 7: Postmortem

The [i] vowel was the most confusing part to me, since the amplitude is so low.

Segmentation

The segmentation here is a little hard to see, but I think it’s atually much easier to see on the waveform than on the spectrogram. I’m looking at the big changes in the shape of the waveform, and in the changes in amplitude. Segmentation

First Guess

Now I know that the final segment is [l]. It’s almost time for class so I’m going to cheat and use my word generator to help me find things that start with an approximant or nasal with this frame. That gives me the list:

Of those, I like [ɛ] as a vowel better since it should have a lightly lower F2. So I just need to pick where I think [ɹ] or [n] is the more likely onset… The movement of the formants makes me ever so slightly think that [ɹ] is better.

My second guess is

+ɹ
+ɛ
+s
+ə
+l

Woohoo!

Postmortem

Thinking about formant transitions and segmenting using the waveform were the big ‘wins’ of the day.

My first guess is

Rats, that’s not great.

Revision

Maybe this is the once in a blue moon that a final segment is not devoiced; there are a lot of words in English that end in [mp]… Given that coda, I think [st] is the most likely onset. So then the big question is about the vowel quality. There are few words that fit the bill:

We know it’s not stamp, and between stump and stomp I think stump makes more sense with the F2 we’re seeing.

My second guess is

+s
+t
+ʌ
+m
+p

Wooohoo!

Postmortem

I think I was too much of a smart aleck on this one, ignoring acoustic cues for things I think were phonologically likely.

Excuse me? I was so confident about that. I guess it could be <minds>, but I don’t see a stop release anywhere here. My third guess is

Step 5: First Guess

My first guess is:

Not looking great.

Revision

I’ll revise to a voiceless version of the /-s/ morpheme, and switch the place of the first stop. I’ll also try another approximant for those segments 2-3 in hopes of getting more info.

My second guess is:

+k
-ɹ
-oʊ
!t
-s

Huh, okay so what I thought was a final sibilant must be the [t] stop. I’ve run out of approximants for segments 2-3, so there must be a nasal there. Since there’s no k+nasal clusters in English, segment 2 must be a very short unstressed vowel.

My third guess is:

+k
+ə
+n
+a
+t

Postmortem

This is a word where I never would have guessed that that is how CMU transcribes the phones. What is going on with that first schwa? Looking at the spectorgram in hindsight, F2 is fairly high and F1 low, and listening to the audio it sounds more like [ɪ] than [ə].

Segmentation

The segmentation is confusing to me. What makes it unclear is that there’s a lot of sonorant segments next to one another, and because of that there aren’t clear temporal transitions. There may be a sneaky middle segment, or something showing up as weak formants at the end of the word.

First Guess

My first guess is

-k

Revision

Hmm, so my segmentation was wrong in a way that I didn’t expect. What if the dip in F3 that I saw at the beginning was because of an [ɹ] in an onset cluster?

My second guess is

+t
+ɹ
+eɪ
+l
+ɚ

Postmortem

I think the sign of the [ɹ] existing is most evident in the amplitude in the waveform. I also think the little blip before the regular periodic pattern is an air pocket releasing when the tongue moves anteriorly to make the [ɹ].

Segmentation

I am a little nervous about this segmentation. My one worry is that what I’ve called a first segment (and that I think is a fricative of some kind) is actually a weird-looking glottal stop for an onset-less first syllable. Segmentation

First Guess

My first guess is

-f
+a
!p
-l

Revision

Uh-oh, does that mean there’s something wrong with the segmentation, or is it that the release of the p is not visible from the start of the word? It really doesn’t look like there’s a release in the beginning, so I think maybe what I saw as a voiceless approximant after the stop is just an inconsistent amount of aspiration after the closure, Then the segment after the stressed vowel could be a rhotic, since there is some movement of F3.

My second guess is

+h
+a
+ɹ
+p
+ɚ

Woohoo!

Postmortem

I think what would have helped me to see the missing [ɹ] would have been to look more carefully at the amplitude changes of the waveform. But still, they aren’t going in the direction I would expect (I want the vowel to be louder). It is also hard because all of the formants are dipping down, not just F3. So there is an overlap between the transition for [ɹ] and the one for [p].

First Guess

Wow, is is a super sonorant word. The only easy part of segmenting this is the central segment, where the formants drop off. I’m assuming that the silence at the beginning is just a little bit of prevoicing, because I don’t see a strong closure on the waveform and I already have 5 segments without a stop. I tried to learn from yesterday and use the waveform as a primary guide for segmentation this time.

My first guess is

+w
+i

Woohoo! I feel vindicated from my poor performance yesterday.

First Guess

The segmentation today is more confusing to me, but I drew these boundaries mainly going off of the strong vertical lines I see in the spectrogram, indicating release bursts.

I’m going to go with a word for my first guess.

+s
-p
-l
!i
-n

Revision

Huh, guess the double releases I saw in what I called segments 2-3 were a red herring. I’ll have to pick another stop to go there, and since I don’t see velar pinch I’ll go with [t]. Now for the final 2 segments after the vowel. This is a nasal or an approximant followed by either a stop or a fricative. The words I’m thinking of that fit that are <steals> <steeled>, <steams>, and <steamed>. Of these, I think the energy is still too low for a final [z], so I’ll say that the blip at 450 ms is a release for a [d]. Between [m] and [l], there are a couple of things I’m looking for. First, [l] and [d] have the same place of articulation, so I could envision a smooth transition with little visible closure, which works here. For [m], since the lips have to open and the tongue make a new closure, I’d expect more of a closure than I see here. Also, in this position in English I would expect [l] to be velarized, which is maybe why that F3 was dipping.

My second guess is

+s
-t
+i
-l
-d

Wow not a great day for the home team. I still have unused hypotheses, so let’s try those.

My third guess is

+s
+k
+i
-m
-z

Rats, I am really batting zero out here today. I need to backtrack and look for more clues. Theres is a dip in the amplitude during what I’ve been calling “the vowel.” What if this is a disyllabic word and the second syllable doesn’t have an onset? That would explain the change in amplitude and also where this extra segment is coming from. The only word I can think of with that pattern is <skiing>, so I’ll try that.

My fourth guess is

+s
+k
+i
+ɪ
+ŋ

Woo hoo!

Postmortem

What I learned from today is: don’t ignore cues from the waveform! I am still chewing on why it looks like that [k] is released twice.

First Guess

Today I got to do the gramle with my incredible Phonetics class. This is our rationale:

Our first guess was:

-u
!d
+n

Revision

After viewing what we got partially right, we were confident that the last segment should be [d]. We talked about not wanting to change the place in the vowel space we’re looking for our first segment, but thought that maybe [oʊ] would work since the formants don’t move very far and it can be on the shorter side for diphthongs. When we combined that with what was left in our hypothesized candidates for segments 2 and 3, we ended up on the word <opened>.

Our second guess was

+oʊ
+p
+ə
+n
+d

Woo hoo!

Postmortem

We listened to the audio, and the final [d] was in fact devoiced. Not too shabby for only being in Week 6 of 10!

Nothing is coming to mind, so I’ll not start with a word. My first guess is

Wow, I don’t think I’ve gotten so wrong so far.

Revision

The alternative to my idea about the fricativeis that we are actually looking at affricates. If that’s the case, then when I thought was a closure for a stop is the closure for the affricate. On second loo, right at the beginning it does look like there’s a release burst in the waveform so there might be a stop there. Since F2 starts low there might be lengthening for lip pursing. Combined with the short aspiration I’m guessing this is a [b].

Resegmentation

My second guess is

-b
-aɪ
-tʃ
!dʒ

I’m sort of at a loss for that last segment, but maybe it’s a wildly aspirated [t] for <budget>

My third guess is

+b
+ʌ
+dʒ
+ɪ
+t

Postmortem

If you listen to the [t], it is really weird. I think what I’ve learned is to make sure that I’m looking at both the waveform and the spectrogram, and to remember my own rule that weird things happen at the end of words.

May 1, 2025

Today we did the whole gramle in my Phonetics class. I unfortunately forgot to take a screenshot but the word was <furbish>. We got the first fricative and the final coda very quickly. The first coda and second onset were really troubling for the class. We believed that the stressed vowel was something with a mid-F1 and mid-low-F2, and started with wedge based on that. In the end, it was a central vowel but we failed to see the rhoticity. What threw everyone off was the manner of articulation of the third segment. There were shadowy formants that had us going down the nasal, approximant, fricative line. We did notice at the very end what looked like a release burst in the waveform, that enabled us to guess <foppish>. But in the end we had a 50/50 toss up between fervish (I still don’t know what that means) and furbish.

Our guesses were:

1:

+f
-ʌ
-n
-ə
-s

2:

+f
-u
-l

+ʃ

3:
