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?
Why have I suddenly started using /asd/ instead of
[asd]? (slant brackets instead of square brackets)
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)
–
–
Compare pit vs bit
That is a voicing difference
Aspiration is much less important in English than in
Chinese
–
Can you explain why?
5
Because aspiration 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
Slant brackets are used for phonemic transcriptions //
Square brackets are used for phonetic transcriptions []
This is an important point
–
We will return to it later

This week
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, pp252-256. What are
the parameters for describing vowels (like
voicing, airstream etc with consonants)?
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
Fromkin (p254) invites you to compare 四
with 速
Or more straightforwardly, compare ㄧ with
ㄩ
–
The difference should be quickly apparent
13
So, the 3 parameters are…

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

British
American

Links for vowel sounds
General American (GenAm)

Cardinal vowels (those shown on the IPA chart)
and diphthongs of RP and GenAm

http://www.yorku.ca/earmstro/ipa/vowels.html
This is one of the best designed web interfaces I have
ever seen, by the way!
17
Diphthongs
Fromkin describes these as a vowel + a glide
(p255) so /bajt/; /bawt/
Most other writers 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
18
Tense vs lax vowels: Fromkin
British vowels are short /I/ or long /i:/
–
American vowels are generally described as either tense or lax
–
See p255
Some of the tense vowels correspond to diphthongs in British
pronunciation
–
–
–
–
Some people write the transcription with the colon (:)
/lod/ /ləʊd/; /led/ /leId
This means that /e/ is available to transcribe American /ɛ/
so, “led” is /lɛd/ in American transcription, but /led/ in British
transcription
And /led/ would be spelled “laid” to an American linguist
A question for you to consider:
–
We talked about 3 parameters for describing vowels. Why don’t we have
a 4th parameter “length” or “tenseness” or “laxness”?
19
Quizzes, exams etc etc
In week 10, there is an 80 minute 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 Fromkin, 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
20
Quizzes, exams etc etc
The quiz last time was slightly disappointing
So, next week there will be another quiz
–
–
All consonants (including approximants/glides and
affricates) found in English and Mandarin
Vowels of American English, classified according to
Figure 6.5 in Fromkin
If I ask for a symbol, write only one symbol
If I ask for the 3 or 4 parameters which define a
sound, write the term for each of the 3 or 4
parameters!
