Instead of stressed and unstressed syllables, French sentences are divided into rhythmic groups (groupes rythmiques or mots phonétiques). A rhythmic group is a group of syntactically-related words in a sentence.* There are three basic kinds:
- Nominal (noun) groups
- Verbal groups
- Prepositional groups
The last syllable of each rhythmic group is accentuated in two ways.
1. Intonation
Intonation refers to the pitch of someone's voice. The last syllable of each rhythmic group inside the sentence is pronounced at a higher pitch than the rest of the sentence, while the final rhythmic group's final syllable is pronounced at a lower pitch. The only exception to this is questions: in this case, the last rhythmic group's final syllable is also at a high pitch.
2. Tonic accent
The French tonic accent is a slight elongation of the final syllable in each rhythmic group. Rhythmic groups normally have up to 7 syllables, but this varies according to how quickly they are being spoken. If a sentence is spoken very quickly, some of the shorter rhythmic groups may be joined together. For example, Allez-vous au théâtre ? is short enough that you might choose to pronounce it as a single rhythmic group rather than Allez-vous | au théâtre ?
The following chart shows how rhythmic groups fit together. Click on the Listen links to hear each sentence pronounced at two different speeds. Due to the (lack of) quality of internet sound, I exaggerated the accentuation in the slow version. Please remember that this is just a guide to help you better understand rhythm and improve your French listening and speaking skills.
