Suprasegmental phonology

Many significant sound contrasts are not the result of differences between phonemes. For example, stress is important: when the word 'import' is pronounced with the first syllable sounding stronger than the second, English speakers hear it as a noun, whereas when the second syllable is stronger the word is heard as a verb. Intonation is also important: if the word 'right' is said with the pitch of the voice rising, it is likely to be heard as a question or as an invitation to a speaker to continue, while falling pitch is more likely to be heard as confirmation or agreement. These examples show sound contrasts that extend over several segments (phonemes), and such contrasts are called suprasegmental. We will look at a number of other aspects of suprasegmental phonology later in the course.
