It's possible you're thinking of suprasegmental features, which are features of speech that go beyond individual sounds (segments). These features apply to larger units of speech, such as syllables, words, or phrases.
Here are some examples of suprasegmental features:
* Stress: The relative emphasis placed on a syllable within a word. For example, the word "record" has stress on the first syllable, while "record" has stress on the second syllable.
* Tone: The pitch contour of a word or phrase, which can convey different meanings. Many languages, such as Mandarin Chinese, use tones extensively.
* Intonation: The rise and fall of pitch over a sentence or phrase, which can convey emotions and attitudes. For example, a statement ending with a falling intonation is typically considered declarative, while a question ending with a rising intonation is considered interrogative.
* Rhythm: The pattern of stressed and unstressed syllables in speech. Languages can have different rhythmic patterns, such as stress-timed or syllable-timed.
So, while "supra-segmental sounds" is not a common term, it might be a way of referring to the features of speech that go beyond individual sounds.
