Syllables form measures when one or more are combined with one stress. As a rule, significant words are highlighted in separate bars, and non-significant words are adjacent to a word in which there is stress.
Measures constitute a phrase. In phonetics, this unit is not at all identical to a grammatical sentence: it happens that one sentence consists of several phrases, or one phrase includes several sentences. The phrases are separated by pauses, during which the speaker draws air into his lungs to continue speaking. Phrases are combined with intonation, which can include raising and lowering the voice (melody), the ratio of strong and weak syllables (rhythm), acceleration and deceleration of pronunciation (tempo), strengthening and weakening of exhalation (intensity), changing the general timbre of speech.
