Parameters for describing
consonants
So far (this is not complete yet) we have
–
–
–
–
So, [p] is …
–
–
–
–
Airstream (usually the same for all consonants)
Place of articulation
Voicing
Manner of articulation
egressive pulmonic
bilabial
voiceless
plosive
This was what I was expecting in the quiz!

3
Affricates in Mandarin
/tsʰ/ and /ts/
/tʂʰ/ and /tʂ/
/tɕʰ/ and /tɕ/
–
–
Can you guess what they are?
What is the ʰ?
ㄘ and ㄗ
ㄔ and ㄓ(retroflex affricate)
ㄐ and ㄑ(alveolo-palatal affricate)
4
Aspiration
Aspirated and unaspirated consonants
–
ㄅ is unaspirated [p]
» Voicing for the next sound (a vowel) begins immediately
after plosion
–
ㄆ is aspirated [ph] (puff of air)
» Vocal folds remain open briefly, after the stop is released
English: spit vs pit (aspiration difference)
Aspiration is much less important in English than
in Chinese
–
Can you explain why?
5
Because aspiration in Mandarin is
phonemic (also, tone in Mandarin is
phonemic)
pʰ and p are two different phones; two different
sounds
but in Mandarin they are different phonemes
–
–
–
/pʰa/ (ㄆㄚ) and /pa/ (ㄅㄚ) represent different
meanings
in English pʰ and p do not help to distinguish meaning
There are no minimal pairs like pʰa and pa
6
IPA: approximants (all voiced)
An approximant
–
–
2 common realizations of /r/ (in addition to the trills
described earlier)
–
–
occurs as a consonant in syllabic patterning (CVC)
but, it’s like a vowel, because the articulators usually don’t touch.
[ɻ] retroflex approximant of Mandarin
[ɹ] alveolar approximant of English
A palatal approximant [j], often corresponding to the
English spelling “y”
A labial (=with rounded lips) velar approximant [w]
Then there is a lateral approximant [l]
–
Lateral = “side”, that is where the obstruction is

8
Vowels vs consonants
Consonants
–
There is some obstruction in the vocal tract
(=the mouth or throat)
Vowels
–
There is no such obstruction (the air flows
freely)
9
Regional accent variation
English accents
–
–
The consonants are generally the same
The vowels are often very different
Mandarin Chinese accents
–
Pronunciation of consonants often varies
widely according to region
10
Describing vowels
Say [i] followed by [æ] (like cat)
–
–
–
Think about where your tongue is
Look in a mirror
What changes? What can you say about the
position of the tongue in the two cases?
This is one of the parameters of vowel
description
11
Another parameter
Now compare [ɑ] (father) with [æ] (like
cat)
You can also try comparing the vowels in
ㄢ and ㄤ
Notice any difference?
This is the second distinguishing parameter
(factor)
12
The third parameter
Compare 四 with 速
Or more straightforwardly, compare ㄧ with
ㄩ
–
The difference should be quickly apparent
13
So, the 3 parameters are…
14
The IPA vowel chart
• This is a stylized
representation of the
inside of the mouth
• It shows
– the cardinal vowels
• marked by black dots
– and the approximate
position of vowels common
in many languages
• The next slide shows the
position of English vowels
on the same kind of chart
15
British
American
16
This week’s homework
• Sound description, recording and
animation. Take a look at
http://www.uiowa.edu/~acadtech/phonetics
/about.html# and click on “English library”.
• Read about vowels again (page 48ff).
What are the parameters for describing
vowels (like voicing, airstream etc with
consonants)?
17
Diphthongs
Yule describes these as a vowel + an approximant
(p49) so /bajt/; /bawt/
We can also say there are two vowels involved
–
–
–
–
–
an initial vowel, in “bite” or ㄞ = a
a target vowel, in “bite” or ㄞ = I
the tongue moves towards I
but doesn’t actually reach its target
Check the cool website for a demo

Midterm exam
On 20th November, there is a midterm exam. You can
expect questions on:
–
–
–
–
Anything I talked about in class
Anything on these slides
Anything from the web resources I referred you to
Anything from Yule, in the sections related to what we covered in
class
For some questions, you will write a short answer of a few
words, maybe a number, maybe a symbol
For other questions, you will write a short paragraph.
You will get a half credit for anything you write in Chinese
