Putting It to Work

Phonetics and the IPA

Course 1 · Chapter 10 · Putting It to Work

You have the whole toolkit: a notation (Chapter 1), the machinery of speech (2), consonants and vowels (3 to 5), the chart (6), English in three accents (7), running speech (8) and the sound itself (9). This last chapter ties them into one working routine and says honestly where the IPA stops.

The idea in a box

Wikipedia says phonetics is "traditionally divided into three sub-disciplines": articulatory, acoustic and auditory. This course covered the first two in depth (Chapters 2 to 5 and Chapter 9) and touched the third only in passing. Auditory phonetics, the study of how listeners perceive speech, is a natural next topic.

The Course in One Table

Chapter	Core idea
1 Why Sounds Need a Notation	spelling is not sound; [brackets] versus /slashes/; broad versus narrow
2 How Speech Is Made	airstream, voicing, oral versus nasal, active and passive articulators, places
3 Consonants: Place and Manner	label = voicing + place + manner
4 More Consonants	new places; ejectives, implosives, clicks
5 Vowels	label = height + backness + rounding; cardinal vowels
6 Reading the IPA Chart	layout, diacritics, length, stress, tone
7 Transcribing English	lexical sets; RP, General American, Scottish English
8 Connected Speech	assimilation, elision, weak and strong forms
9 Acoustic Phonetics	formants, VOT, Praat

A Transcription Routine

When you transcribe anything, work through the same questions in the same order. This routine is my summary of the course, not a standard from a source.

// Transcription routine
Name the accent (RP, General American, Scottish English ...).
Decide the level: broad /slashes/ or narrow [brackets].
For each vowel: find its lexical set, then use the accent's symbol.
For each consonant: voicing + place + manner, then the symbol.
Check the accent's consonant rules: rhoticity, flapping, [ʍ], [x].
Add stress (ˈ), length (ː) and any needed diacritics.
If the speech is connected, ask: assimilation? elision? weak form?

Worked example

Take handbag from Chapter 8 in careful RP-style speech and then in running speech. Wikipedia gives both forms:

// handbag (forms from Wikipedia, Assimilation)
/ˈhændbæɡ/       citation form
[ˈhæmbæɡ]        rapid speech: [d] elided, [n] becomes [m]

Step 7 is what separates the two lines: elision removes [d], and place assimilation turns [n] into [m] before the bilabial [b]. The accent is not stated by the source, so this course does not claim one.

Where the IPA Stops

It is a notation, not a measurement. Chapter 9's formants and VOT are numbers; IPA symbols are categories. Two speakers of [i] can have different formants.
Phonetic symbols are positions, not guarantees. Chapter 5 warned that "the same" vowel symbol is not identical across languages. The cardinal-vowel system needs training to use well, and trained phoneticians agree less the further a vowel is from a cardinal value (Chapter 5, citing Ladefoged).
Transcription is a choice. Broad or narrow, one accent or another: the same speech can be written several defensible ways.
The chart is revised. Chapter 1 recorded that the latest substantive revisions date from 2015 and 2005 according to the Association, against "revised 2020" in Wikipedia.

Watch out: do not trust a transcription you cannot name

A transcription with no named accent and no stated level (broad or narrow) cannot be checked. When you read someone else's, look for those two things first. When you write your own, always put them in.

Where to Go Next

Direction	Why
Historical Linguistics	sound change (the drift along the cline of stricture in Chapter 3, assimilation and elision in Chapter 8) is how languages change over centuries. A Historical Linguistics course is planned on this site, not yet written.
Auditory phonetics	the third branch of phonetics, perception, which this course only touched
A real recording	record yourself with Praat (Chapter 9) and transcribe it with the routine above
The Handbook and chart	the full IPA chart, free from the International Phonetic Association, is the best next reference

Note on sources

The three-branches statement comes from Wikipedia's Phonetics article (read to its first 100,000 characters; the part on applications was not reached, so this chapter makes no claims about speech technology, forensics or teaching). The handbag forms come from the Assimilation article. The recap table, routine and "where to go next" are mine.

Try It Yourself

Exercise 1

Run the routine on car in General American, from Chapter 7. Say which step handles the /r/ and what the result is.

Exercise 2

Take would you from Chapter 8. Give the citation form, the running-speech form and name the process.

Exercise 3

Choose your own accent and one short sentence. Transcribe it using the routine, saying which steps you used and what you are unsure of.

Chapter 10 Quick Reference

Phonetics has three sub-disciplines: articulatory, acoustic, auditory
Routine: accent, level, vowels by lexical set, consonants by recipe, accent rules, marks, connected-speech check
Transcription is a notation, not a measurement, and always a choice
Always state the accent and the level

Course complete

Phonetics and the IPA is finished. You can name any sound by its recipe, read the IPA chart, transcribe English in three accents, spot connected-speech processes and read a formant. A Historical Linguistics course is the planned next step.
