Conclusions
Introduction• Aims
• Examine language universal claims of the “segmental anchoring” hypothesis (Ladd et al., 1999)
• Examine influence of syllabic structure on tonal alignment in French
• Learn about French intonation and intonation structure more generally
• Approach• Record two read speech corpora
• Examine tonal alignment and tonal scaling

Segmental anchoring
• Hypothesis about the nature of tonal alignment and tonal scaling, cross-linguistically (Arvaniti et al., 1998, Ladd et al., 1999)
• Languages examined for hypothesis include: CatalanDutchEnglishGerman GreekRussianSpanish

Conclusions
Segmental anchoring and tonal alignment
Tonal alignment:timing of peaks and valleys in the fundamental frequency (F0) curve with segmental landmarks
Segmental anchoring claim: “… when we look more closely at the differences
of detail that have been documented between one syllable structure and another or between one language and another, we find that both the beginning and the end of the f0 movement can and must be precisely specified [with respect to segmental landmarks]” (Ladd et al. 2000, emphasis added).

Segmental anchoring and tonal scaling
Tonal scaling: relative position of peaks and valleys in the “tonal space”
Segmental anchoring claim:“Strictly speaking, the segmental anchoring hypothesis makes no predictions about the size of the F0 excursion, yet the idea of independent L and H targets leads to the expectation that rate will have little effect on excursion size.” (Ladd et al. 1999)

Research question 1
• Do French patterns support the claims of segmental anchoring?
• anchors for start and end of F0 rise?
• little variation in position of start and end?(within and across rates)
• fairly constant tonal scaling across rates?• steeper slopes in fast rate utterances?

La cuisine de Marie-Noëlle regorge de victuailles. Un salami qui a été rapporté de Parme suinte d'une graisse très prometteuse. Sur la desserte, un immense compotier déborde de fruits de toutes sortes. Les vitamines qu'ils recèlent naturellement sont un prétexte pour les gourmands. Une pièce-montée en choux et nougatine trône sur le buffet. La pyramide qui dégouline de caramel fera sûrement des amateurs.
‘Marie-Noëlle's kitchen is overflowing with provisions. A salami that was brought back from Parma is dripping with very promising grease. On the side table, a giant bowl is brimming with all kinds of fruit. The vitamins that they naturally contain are just an excuse for people who like to eat. A layer cake with puff pastries and nougatine is prominently displayed on the cabinet. The pyramid, dripping with caramel, will surely be appreciated.’

ConclusionsSegmental anchoring not supported for French
• No clear anchor point for L2• Rate effects on L2 alignment• Rate effects on F0 excursion size• No stable anchor point for H2
Segmental anchoring claims cannot be spoken language universals. For some languages:• Only one end of a rise is anchored• Rate effects on F0 excursion size• Anchorages rather than anchors
Segmental anchorage is not claimed to be a spoken language universal. Rather, it is one of the range of alignment possibilties.

ConclusionsAlignment of French H2
• Surface alignment differences across syllables structures
• Unified account provided by the notion of segmental anchorage
• For H2, region stretching from ~ 25 ms before the end of the last full vowel of the accentual phrase to the end of the phrase.
• Few peaks in voiced obstruents:– physical constraints on maintaining voicing– preserving of cues to consonant identity

Directions for future research
• Are segmental anchorages found in other languages?
• Articulatory alignment of H2?
• Similarities in other languages with LHLH patterns (Korean, Occitan)?
