using the notes provided by the sound systems of their languages

[alewka]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:

We can see from all this that although phonetics and phonology begin at the level of individual sound segments, they are drawn into a consideration of larger units like syllables, words and combinations of words, and eventually to the various ways in which we use stress and pitch patterns to express subtleties of meaning in utterances. In acts of speech, people use their voice as a complex instrument and, using the notes provided by the sound systems of their languages, pro'd'uce infinite variations of meaning. Phonetics and phonology seek to explain how they do it.

В речи (речевом акте) люди применяют свой голос как сложный инструмент, и используя знаки, которые присутствуют в системе звуков своих языков, создают бесконечное количество различных значений.

PS. я думаю, что notes - это набор звуковых знаков, фонем, присущих данному языку
