What is articulatory phonetics?

Articulatory phonetics is the study of the production of speech sounds in the vocal tract.

Résumé

TLDRThis video is part of a series on articulatory phonetics, specifically focusing on vowel sounds in North American English. It contrasts monophthongs, which have a single vowel quality, with diphthongs, which have two. Unlike consonants, vowel description doesn't involve constriction in the vocal tract and instead uses three criteria: height (how high or low the tongue is), backness (how far front or back the tongue is), and roundedness (whether the lips are rounded). The video describes these criteria in detail, offering examples like [i] as a high, front vowel and [u] as a high, back rounded vowel. The proper order to refer to vowel sounds is height, then backness, and finally roundedness. While diphthongs are briefly mentioned, the video focuses on monophthong classification. It encourages viewers to explore other videos in the series for more information on consonant sounds and the international phonetic alphabet.

Chronologie

00:00:00 - 00:05:03
In this segment, the video introduces the topic of articulatory phonetics, which deals with the production of speech sounds in the vocal tract. The focus is on vowel sounds used in North American English, particularly distinguishing monophthongs, which involve one vowel quality, from diphthongs, which involve two. Unlike consonants, vowels do not require airflow constriction in the vocal tract, therefore the criteria for describing them differ, including height, backness, and roundedness. The discussion begins with an explanation of vowel height.

Hey everyone thanks for joining us. Welcome!
00:00:08
So today we'll be talking more about articulatory phonetics,
00:00:12
which again is the study of the production of speech sounds in the vocal tract.
00:00:17
If you haven't already, please take a few minutes to look at our other videos in this series
00:00:20
on describing consonant sounds and navigating the international phonetic alphabet.
00:00:26
In this video we will be talking about how linguists describe vowel sounds.
00:00:30
Just a couple of notes. First again like in the constant video
00:00:35
we will only be talking about the phonetics of spoken language rather than sign languages
00:00:40
and we will be talking about the vowel sounds as they are used in North American English.
00:00:47
There are two types of vowel sounds:
00:00:49
Monophthongs and Diphthongs.
00:00:52
Monophthongs involve one vowel quality and diphthongs involve too vowel qualities.
00:00:57
When linguists are describing vowel sounds, we have to rely on a different set of criteria
00:01:02
for what we used in describing consonants because
00:01:05
remember, vowels do not involve the constriction of airflow in the vocal tract.
00:01:10
so our tongue doesn't approach an anatomical landmark like they do with consonants
00:01:15
so the three criteria that linguists use when describing vowel sounds are
00:01:19
height, backness and roudedness.
00:01:22
Let's talk about each of these in turn.
00:01:29
Height refers to how high or or low the tongue is in the mouth when producing the vowel.
00:01:35
For example, consider the vowel sounds, [i] and [a].
00:01:39
If you say both of these vowels in succession,
00:01:42
you should feel your tongue going up and down as you say [i], [a], [i], [a], [i], [a].
00:01:49
In terms of height, vowels are either considered high, mid, or low.
00:01:55
[i] is an example of the high vowel.
00:01:57
[ɑ] is an example of the low vowel.
00:02:18
Backness refers to how far front or back the tongue is when producing the vowel.
00:02:23
As with vowel height, this can be tricky as it takes some practice,
00:02:27
but consider the vowels, [i] and [u].
00:02:32
If you say these vowels in succession, you may notice that your tongue is
00:02:35
moving forward and backward as you say [i] [u] [i] [u] [i] [u].
00:02:49
In terms of backness, vowels are either considered front, central or back.
00:02:55
Remember that [i] is a high vowel but it's also a front vowel.
00:02:59
while [u] is a back vowel.
00:03:06
The third criteria that linguists use when describing vowels is roundedness.
00:03:11
Roundedness means whether or not the lips are rounded when producing the vowel.
00:03:15
This is something that's very easy as you can feel and see when you are producing a rounded sound,
00:03:21
or when the person that you're talking to is producing a rounded sound.
00:03:25
so again take the two sounds that we just used.
00:03:27
[i] and [u].
00:03:29
[u] as you can clearly see and feel is a rounded vowel whereas [i] is not a rounded vowel.
00:03:43
[i] [u] [i] [u] [i] [u]
00:03:58
Just like with consonants there is a specific order that linguist use when describing vowel sounds.
00:04:03
It is height, then backness, then roundedness.
00:04:08
For example, [u] is a high back rounded vowel.
00:04:13
[Ê] is a low front urounded vowel.
00:04:18
Remember, so far we've only been talking about monophthong vowels.
00:04:22
If you want to categorize diphthongs in terms of these criteria
00:04:25
we must do so for by starting vowel quality as well as the ending vowel quality.
00:04:30
But we won't worry about that in this video.
00:04:36
Alright so what do we cover in this video?
00:04:39
We talked about the criteria that linguist use when describing vowel sounds,
00:04:43
and the order that those criteria must appear in,
00:04:46
and that's pretty much it for this video.
00:04:47

00:04:51
