2. Today  What is Phonetics?  Decoding the speech stream  Principles of phonetic transcription  IPA Readings: 3.1-3.2

3. Phonetics  The scientific study of human speech sounds How they are produced (articulatory) How they are perceived (auditory) Their physical properties (acoustic)

4. X-ray movie “Why did Ken set the soggy net …on top of his deck?” http://hctv.humnet.ucla.edu/departments/linguistics/VowelsandConsonants/course/chapter1.1/chapter1.1.htm

5. Decoding the speech stream  The speech signal is a continuous stream of sound  No ‘spaces’ between words in speech

6. Decoding the speech stream How many words in the following sentence?

7. Chicken Little parsed as saying: “The sky is falling” (untrue)......rather than his actual warning: “This guy is falling.” (true)

8. Decoding the speech stream How many sounds in the following words? ‘leaf’ ‘feel’

9. Decoding the speech stream ‘leaf’ [lif] vs. ‘feel’ [fil] forwards ‘feel’ [fil] vs. ‘leaf’ [lif] backwards ‘lull’ vs. ‘llul’ backwards

10. Decoding the speech stream  Sounds in a string are continuous, yet we perceive them as discrete, separate sounds

11. Goals for Phonetics section:  Be able to identify human speech sounds  Learn symbols used for transcribing speech sounds  Describe and classify sounds according to articulatory properties

12. Phonetic transcription  The most widely used tool in phonetics is transcription

13. International Phonetic Alphabet (IPA)  A standardized set of symbols for transcribing all possible human speech sounds  One-to-one correspondence between symbol and sound We will use “symbol” = IPA “letter” = spelling (orthography)

15. Why use the IPA?  Some languages have no writing system  There is no one-to-one correspondence between letters and sounds: Same letter — different sounds dad, father, about, many Same sound — different letters believe, people, amoeba, tree Several letters used for one sound shoot, nation, chord, chip

16. Why use the IPA? One letter used for several sounds box, use Some letters have no sound gnaw, sword, debt, damn, bomb [baks] [juz] [nç]...[bam]

17. IPA preview  Some symbols will look and sound familiar: [b n w]  Some will look familiar, but sound strange: [x q]  Some will sound familiar, but look strange: [S T N]  Some will look and sound unfamiliar: [/ µ ß]
