| Most speakers are largely unaware of the extent of allophonic variation in their language. |
| When listening for allophonic variation, it is necessary to try and distance yourself from a language. |
| Typically, languages with a small phoneme inventory allow for quite a lot of allophonic variation. |
| There is some degree of allophonic variation in the alveolar stops. |
| Vowel length may also have arisen as an allophonic quality of a single vowel phoneme, which may have then become split in two phonemes. |
| Stress is often reinforced by allophonic vowel length, especially when it is lexical. |
