WEBVTT 00:00:05.927 --> 00:00:10.623 Hi, in the previous video, we discussed the different ways in which languages can 00:00:10.623 --> 00:00:12.704 produce different consonants, and 00:00:12.704 --> 00:00:15.740 the ways in which they can distinguish between them. 00:00:15.740 --> 00:00:20.690 We have seen our three dimensions which are relevant here. 00:00:20.690 --> 00:00:24.900 The first is place of articulation, where in the mouth do I produce the sound? 00:00:25.950 --> 00:00:28.400 The second is manner of articulation, 00:00:28.400 --> 00:00:31.970 how is the air stream modified when I produce the sound? 00:00:32.970 --> 00:00:36.850 And the third is voicing, what do I do with my vocal cords? 00:00:37.930 --> 00:00:38.750 I'm going to discuss 00:00:38.750 --> 00:00:43.460 these issues a little bit more now with my students, Inge and Marten. 00:00:43.460 --> 00:00:46.280 >> Yes I'd like to ask the first question because I was wondering 00:00:46.280 --> 00:00:49.390 are there consonants that occur in all languages? 00:00:49.390 --> 00:00:51.940 >> Yeah, right, that, that's a very interesting question. 00:00:51.940 --> 00:00:55.840 It's actually a question which has inspired linguists forever or 00:00:55.840 --> 00:01:00.620 at least since the 19th century and the answer seems to be 00:01:00.620 --> 00:01:05.190 that there at least two good candidates for such consonants. 00:01:05.190 --> 00:01:09.420 This is the M sound, and the T sound. 00:01:09.420 --> 00:01:13.360 They, linguists don't necessarily agree on them, there are some linguists who say 00:01:13.360 --> 00:01:17.300 that maybe, one of, or two of these sounds don't occur in all languages. 00:01:17.300 --> 00:01:19.800 But I think, it's fair to say that they do. 00:01:19.800 --> 00:01:21.740 >> But why would it be M and T only? 00:01:22.970 --> 00:01:28.450 >> Well, it's probably M and T because they are simple. 00:01:28.450 --> 00:01:30.590 For instance, they are easy to make. 00:01:30.590 --> 00:01:31.910 It's very easy to make a T. 00:01:31.910 --> 00:01:33.240 I use the tip of my tongue. 00:01:33.240 --> 00:01:35.330 The tip of my tongue is very flexible and 00:01:35.330 --> 00:01:39.450 I put it basically at its natural place just behind the teeth. 00:01:39.450 --> 00:01:41.670 T, that's a very simple sound to make and 00:01:41.670 --> 00:01:46.090 it's a wonderful consonant, and M is also very simple to make. 00:01:46.090 --> 00:01:48.298 I just close my lips. 00:01:48.298 --> 00:01:51.035 Furthermore, it's very easy to see. 00:01:51.035 --> 00:01:55.260 It's very easy to, to see that somebody is making an M sound. 00:01:55.260 --> 00:02:00.170 As a matter of fact, it's sometimes claimed that all languages, or 00:02:00.170 --> 00:02:03.810 many languages at least have the same word for 00:02:03.810 --> 00:02:07.330 mother, it's mama, something like that. 00:02:07.330 --> 00:02:12.880 And the reason for that might be that it's so easy to make for a child, so the child is 00:02:12.880 --> 00:02:18.029 just lying there in its cradle and saying [mamamama] not meaning anything at all, 00:02:18.029 --> 00:02:24.013 it's just the mother who observes this and thinks, okay, he must be talking about me. 00:02:24.013 --> 00:02:28.297 >> Okay, so M and T are the easiest sounds, or the easiest consonants? 00:02:28.297 --> 00:02:31.375 And if you look at all languages in the world are they certain? 00:02:31.375 --> 00:02:33.429 What, what constants are there? 00:02:33.429 --> 00:02:36.240 What set? 00:02:36.240 --> 00:02:39.015 >> Yeah, there so the, it's a, 00:02:39.015 --> 00:02:43.667 it's a set of very vast size probably because even this T sound might sound 00:02:43.667 --> 00:02:47.720 quite slightly different in one language from the next. 00:02:47.720 --> 00:02:52.570 But apart from that I, I think if we look at the phonetic alphabet we 00:02:52.570 --> 00:02:56.440 see a few hundred different symbols for consonants. 00:02:56.440 --> 00:02:57.980 So it's quite many. 00:02:57.980 --> 00:03:01.150 >> And is there one language that has most consonants of all? 00:03:02.360 --> 00:03:06.640 >> Well, yeah, I'm, I'm not sure, depends a little bit on how you count. 00:03:06.640 --> 00:03:10.450 But if you want to find one such language, for some reason, 00:03:10.450 --> 00:03:12.640 you have to go to Southern Africa. 00:03:12.640 --> 00:03:17.897 So there's several languages spoken there which seem to have many, many different 00:03:17.897 --> 00:03:22.796 consonant sounds, something between 100 and 150 different sounds. 00:03:26.477 --> 00:03:29.372 >> Okay, I was, I was also wondering then 00:03:29.372 --> 00:03:33.930 I know that we talk mostly about consonants, but what about vowels? 00:03:33.930 --> 00:03:37.300 Are, are there also that many vowels? 00:03:37.300 --> 00:03:39.920 >> Well, yeah, that's another interesting question. 00:03:39.920 --> 00:03:42.100 I think the answer is no. 00:03:42.100 --> 00:03:46.690 So if we look again at the set of symbols which are used in the phonetic alphabet, 00:03:46.690 --> 00:03:48.820 it's definitely smaller. 00:03:48.820 --> 00:03:51.870 So that's one side of the answer. 00:03:51.870 --> 00:03:56.388 Also, within a language, if you have many different you 00:03:56.388 --> 00:03:59.311 use more consonants than vowels within one 00:03:59.311 --> 00:04:00.820 >> Okay. >> in the same language. 00:04:00.820 --> 00:04:02.460 >> And is there a reason for that? 00:04:02.460 --> 00:04:08.160 I mean, if there are just fewer vowels in general, doesn't mean that a language 00:04:08.160 --> 00:04:12.660 always also needs to have fewer vowels than consonants. 00:04:12.660 --> 00:04:13.690 >> Yeah, that's true, 00:04:13.690 --> 00:04:17.899 but I think there are two sides to this, to the answer to this. 00:04:17.899 --> 00:04:24.260 So on the one hand vowels, it's more difficult to distinguish 00:04:24.260 --> 00:04:29.170 between vowels, because the difference between vowels and consonants again is, in 00:04:29.170 --> 00:04:34.230 order to produce consonants, you need some obstruction somewhere in your mouth. 00:04:34.230 --> 00:04:36.860 In order to produce a vowel, there's no obstruction, 00:04:36.860 --> 00:04:40.760 you just transform the sound when it's going out in some way. 00:04:40.760 --> 00:04:45.370 And there's just many more different ways of making an obstruction in your mouth 00:04:45.370 --> 00:04:48.440 than transforming a sound like that. 00:04:48.440 --> 00:04:52.040 That seems to be an important part of the answer. 00:04:52.040 --> 00:04:54.550 Now you can also ask, how then come, 00:04:54.550 --> 00:04:58.900 that within a language there are still more consonants than vowels? 00:04:58.900 --> 00:05:02.774 So some languages have many different vowels. 00:05:02.774 --> 00:05:05.469 So we are, all three of us are speakers of Dutch, and 00:05:05.469 --> 00:05:08.186 Dutch actually has quite a lot of different vowels. 00:05:08.186 --> 00:05:10.948 It has like 13 different vowels. 00:05:10.948 --> 00:05:14.445 Well, there are languages which have only maybe ten consonants, 00:05:14.445 --> 00:05:17.948 so why are there no languages with 13 vowels and ten consonants? 00:05:17.948 --> 00:05:23.210 The answer to that, I think is also interesting, and that it seems to be that 00:05:23.210 --> 00:05:28.327 consonants have a slightly different function in language than vowels. 00:05:28.327 --> 00:05:33.000 So, consonants seem to reveal more of word meaning. 00:05:33.000 --> 00:05:35.640 We use consonants mostly to reveal word meaning. 00:05:37.060 --> 00:05:39.810 In Semitic languages, like Hebrew and 00:05:39.810 --> 00:05:44.030 Arabic, people write only the consonants and not the vowels. 00:05:44.030 --> 00:05:46.950 They apparently don't need them to still understand it. 00:05:48.130 --> 00:05:51.640 Maybe you even remember from, on the Internet, there 00:05:51.640 --> 00:05:55.712 are these messages where they just took out all the vowels from an English text. 00:05:55.712 --> 00:05:56.410 >> Mm-hm. >> Mm-hm. 00:05:56.410 --> 00:05:59.591 >> And you can still understand those messages. 00:05:59.591 --> 00:06:01.496 So, that's what we use consonants for, 00:06:01.496 --> 00:06:04.950 mostly to, if you see the consonants you already know what the word is. 00:06:04.950 --> 00:06:08.030 So, you don't really need the vowels for that. 00:06:08.030 --> 00:06:13.020 The vowels, we use more for grammar, 00:06:13.020 --> 00:06:16.210 for expressing grammatical structure. 00:06:16.210 --> 00:06:21.100 If I, if I say a sentence and if towards the end of the sentence my voice goes 00:06:21.100 --> 00:06:25.250 really low, in English, what do, where do I do that? 00:06:25.250 --> 00:06:27.160 I do that on the vowels. 00:06:27.160 --> 00:06:30.670 So that's what I use the vowels for more. 00:06:30.670 --> 00:06:33.140 So they seem to have slightly different functions. 00:06:33.140 --> 00:06:38.130 And there's many different words with many different meanings in human language 00:06:39.310 --> 00:06:39.900 but there's not so 00:06:39.900 --> 00:06:45.490 many different kinds of grammatical constructions in the same languages. 00:06:45.490 --> 00:06:49.710 >> Okay, and then finally I had a question which is similar to the one 00:06:49.710 --> 00:06:51.470 earlier about consonants, 00:06:51.470 --> 00:06:56.020 is that, are there also vowels that can be found in all languages in the world? 00:06:57.530 --> 00:06:59.680 >> The, well, probably yes. 00:06:59.680 --> 00:07:03.550 Again, it depends a little bit and people are debating about this. 00:07:03.550 --> 00:07:05.571 People just like to debate about these kinds of things. 00:07:05.571 --> 00:07:09.951 But I think that it's fair to say that 99% of all 00:07:09.951 --> 00:07:14.439 languages have at least three different vowels and 00:07:14.439 --> 00:07:19.780 those three different vowels then are typically A, I and U. 00:07:21.080 --> 00:07:26.120 Again they are sounds which are relatively easy to make. 00:07:26.120 --> 00:07:30.210 They probably are the three vowel sounds which are easiest to produce and 00:07:30.210 --> 00:07:32.410 are also maximally different. 00:07:32.410 --> 00:07:35.610 They're very easy to distinguish from each other. 00:07:41.270 --> 00:07:44.076 In this video, we have seen that there are certain consonants and 00:07:44.076 --> 00:07:48.830 also certain vowels which seem to occur in all languages. 00:07:48.830 --> 00:07:54.080 But that beyond that there's a vast variation. 00:07:54.080 --> 00:07:59.720 We've also seen that there seem to be more consonants than vowels, typically, 00:07:59.720 --> 00:08:03.080 in a language and you've seen that there might be various reasons for that. 00:08:04.950 --> 00:08:08.674 In the next video we're going to look more into language, 00:08:08.674 --> 00:08:13.994 into how all these differences between consonants are actually used in language, 00:08:13.994 --> 00:08:17.718 in speech errors, in the way in which we learn languages, 00:08:17.718 --> 00:08:20.920 and in the way in which languages are structured.
