Overview
Suprasegmental features, also known as prosody, are aspects of speech that are ‘above’ the level of individual speech sounds (segments). They influence pronunciation and meaning but are not tied to a single phoneme. Key examples include stress, tone, pitch, and intonation.
Key Concepts
Understanding suprasegmentals involves grasping several core concepts:
- Stress: The prominence given to a syllable within a word.
- Pitch: The highness or lowness of a sound, often determined by vocal fold vibration.
- Tone: Pitch variations that distinguish word meaning, common in tonal languages.
- Intonation: Pitch patterns that convey grammatical information or attitude.
Deep Dive into Features
Stress
Word stress can change a word’s meaning or grammatical class. For example, in English, ‘record’ (noun) has stress on the first syllable, while ‘record’ (verb) has stress on the second.
Tone and Intonation
Tonal languages, like Mandarin, use pitch to differentiate words that otherwise sound the same. Intonation, on the other hand, uses pitch contours to signal questions, statements, or emotions across phrases and sentences.
Applications of Suprasegmentals
Suprasegmental features are vital in:
- Language Learning: Correct pronunciation and comprehension.
- Speech Synthesis: Creating natural-sounding artificial speech.
- Forensic Phonetics: Speaker identification and analysis.
- Linguistic Analysis: Understanding language structure and variation.
Challenges and Misconceptions
A common misconception is that suprasegmentals are secondary to segmental sounds. However, they are fundamental to natural speech. Challenges include accurately measuring and transcribing these features, especially across different languages and dialects.
FAQs
What is the difference between tone and intonation?
Tone is typically used at the word level to distinguish meaning, characteristic of tonal languages. Intonation operates at the phrase or sentence level, conveying grammatical function or attitude.
How does stress affect word meaning?
Stress can differentiate between nouns and verbs (e.g., ‘pro’ject vs. pro’ject) or simply change the word’s pronunciation and perceived importance.
