Phonetics and the IPA 10, Exercise 1: car in General American

1. Accent: General American.
2. Level: broad /slashes/.
3. Vowel: the vowel of car is the r-coloured one the source lists as
   /ɑːr/ realised [ɑɹ].
5. Accent rules: General American is rhotic, so /r/ is pronounced in all
   spelled-r positions (pearl, car, fort). This is the step that handles the
   /r/.

Result: /kɑɹ/ (broad). The /k/ is a voiceless velar stop (Chapter 3). In
RP, the same word is non-rhotic: /kɑː/ (Chapter 7).
