Slide 2 Towards a P_ToBI: Cu Viana* & Snia Frota** (coordinators) *CLUL, **DLGR/Onset-CEL, FLUL Participants: Isabel Fal, Flaviane Fernandes, Isabel Mascarenhas, Ana Isabel Mata, Helena Moniz & Marina Vigrio PaPI2007 Universidade do Minho Worskshop on the Transcription of Intonation in Ibero-Romance POCTI-SFA-17-745 Slide 3 0. Introduction: background firstA first attempt at a unified transcription of some aspects of Portuguese intonation Brings together studies conducted on lab speech and on speech technology-oriented corpora First joint-venture of two research groups in process of fusion Our proposals are grounded on the understanding of the intonational and prosodic grammar of Portuguese based on the body of research developped in the last 20 years Pioneering work within the AM approach: Viana (1987) Previous studies on P- Intonation almost inexistent Overview: Frota (2000) Slide 4 0. Introduction: topics covered Pitch accents Nuclear accents Prenuclear accents Post-nuclear accent Boundary Tones Levels of prosodic structure relevant to intonational phrasing Distribution of tonal events and phrasing Sparse vs. rich distribution Sentence Types Declaratives Neutral; late/early focus Questions Wh-, yes-no Yes-no: late/early focus Queries, Checks Varieties SEP ; NEP ; BP Speech style Lab speech; professional reading; non-scripted speech; spontaneous speech Slide 5 0. Introduction: main goals In this talk: 1.Basic tunes across sentence types (Lab speech) Data from SEP, NEP and BP Discuss the levels of phrasing in P- intonation 2.New insights from spontaneous, non-scripted speech New accents Differences in the structural position, frequency of use and/or meaning of the same accents Levels of phrasing revisited Research on P-intonation (and P-prosody) is fairly recent, and a ground for consensus is only now being achieved Present labelling proposals are seen as work in progress It is hoped that they can help formulate relevant directions for further research This workshop is a big push Towards a P-ToBI Slide 6 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Three main nuclear accents Slide 7 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Previous peak + fall within the accented syllable Low target usually near the bottom of the speakers range Nucleus in neutral/broad focus statements and questions Frota 1993, 1997, 2000, 2002a; Fal 1995; Vigrio1998 Slide 8 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Peak within the accented syllable immediately followed by a fall; usually followed by compressed pitch range within the same IP Nucleus in narrow/contrastive focus declaratives Frota 1993, 1997, 2000, 2002a; Vigrio1998; Fernandes 2007 Slide 9 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Low target in the accented syllable followed by a rise, starting within this syllable and usually reaching its peak on the next syllable Nucleus in initial/internal IPs within statements (continuation); nucleus in contrastive yes-no questions Frota 2000, 2002b; Frota et al. 2007; Vigrio 2003 Slide 10 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Three main nuclear accentsPre-nuclear position Slide 11 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Accented syllable preceded by immediately previous peak Accented syllable around mid range Common prenuclear accent in statements Frota 2002b Slide 12 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Accented syllable is high F0 peak not after a (substantial) rise or fall Frequent initial accent in statements and questions Frota 2000, 2002b; 2003; Vigrio1998 Slide 13 2. Basic tunes in SEP: pitch accents Description H+L* H*+L L*+H H+!H*H* L+H* Accented syllable is high and immediately preceded by a low target leading to a rise in the accented syllable Fairly infrequent accent in SEP Frota, DImperio, Elordieta, Prieto & Vigrio 2007 Slide 14 2.

Basic tunes in SEP: neutral statement the poet sang a morning angelic Slide 21 2. Basic tunes in SEP: neutral statement H+L*, as in Italian varieties (Grice et al. 2005), or American Spanish (Sosa 1991) the blond girl recorded a song wonderful from-the olive-pressman Slide 22 2. Basic tunes in SEP: neutral statement vs focus (they got) married What about John and Mary? What happened to them? John and Mary broke up ? Slide 23 2. Basic tunes in SEP: narrow/contrastive focus focus Was it an angelic night that the poet sang ? Slide 24 2. Basic tunes in SEP: narrow/contrastive focus focus H*+L, as in Bari or Palermo Italian (Grice 1995, Grice et al. 2005) Who offered spices to the journalists ? Slide 25 2. Basic tunes in SEP: wh-question Same contour as in neutral declarative statements (like in e.g. Standard Italian, Avesani 1995) who painted a morning amber ? Slide 26 2. Basic tunes in SEP: neutral yes-no question the poet sang a morning angelic ? Interrogation is signalled by the tonal boundary (like in e.g. Standard Italian or French, Avesani 1995, Post 2000); unlike in Southern varieties of Italian or in Catalan, Grice 2005, Prieto 2000) Slide 27 2. Basic tunes in SEP: neutral yes-no question An accentual fall plus a boundary rise placed enterily on the final syllable; the pitch in between not controlled by L but resulting instead from interpolation (as in e.g. Bengali) the girls Angolans-FEM read-to-us-it ? Slide 28 2. Basic tunes in SEP: contrastive yes-no question focus the hero drives a Porsche ? Ive seen that movie but I dont recall who drives a Porsche. Slide 29 2. Basic tunes in SEP: contrastive yes-no question focus L*+H HL% acounts for the higher level of the H target (as in L*+HH%, Vigrio 1998, Frota 2000); the end point of the rising pitch is always the pre-final syllable (Frota 2002b) the boys bought slides (for the microscope) ? I would like to know if they bought slides and not something different. Slide 30 2. Basic tunes in SEP: intonational phrasing Major IP: domain for sandhi, e.g. Fricative voicing; final lengthening; wider boundary rise; nuclear accent plus a H boundary (Frota 2000) parenthetical Slide 31 2. Basic tunes in SEP: intonational phrasing Minor IP: smaller final lengthening; smaller boundary rise; but the same sequence nuclear accent plus a H boundary; phrasing into minor IPs depends on phrase length (Frota 2000) parenthetical Slide 32 2. Basic tunes in SEP: intonational phrasing Compound IP (Ladd 1992, 1996, Frota 2000, Vigrio 2003) IPs: sandhi, final lengthening, nucleus plus a tonal boundary (H or L) Relative length of IPs > Compound Inner IP boundary within a Compound or Major IP is weaker than the outer IP boundary (degree of final lengthening and size of pitch excursion) Proposal: Major IP > T%, level 4 Minor IP > T-, level 3 Why not the intermediate phrase? No evidence in terms of the distribution of categorical phonological markers, e.g. T-T% for the IP and just T- for the ip Frota 2000, 2002a,b No evidence for an edge tone that determines the contour from the last pitch accent until the end of the phrase, as in the definition of the ip (B&P 1986, Ladd 1996, Beckman et al. 2005, Grice at al. 2005) Frota 2002a,b Slide 33 2. Basic tunes in SEP: intonational phrasing Subjects more than 8 syllables long (Elordieta, Frota & Vigrio 2005) Long subject the boyfriend megalomaniac of-the Brazilian looked (at the) dark-haired women Slide 34 2. Basic tunes in NEP: neutral statement L* the daughter-in-law of mother talked about the boyfriend Rich distribution of pitch accents (Vigrio & Frota 2003); more IPs by utterance Slide 35 the daughter-in-law of mother talked about the boyfriend Slide 36 2. Basic tunes in NEP: wh-question Same nuclear contour as in NEP neutral declarative statements: L* L% who painted a morning amber ? Slide 37 2. Basic tunes in NEP: neutral yes-no question Interrogation is signalled by the tonal boundary: H(L)% the boys bought slides (for the microscope) ? Slide 38 2. Basic tunes in BP: neutral statement the researcher already gave-back the money Same nuclear contour as in SEP, but rich distribution of pitch accents (Frota & Vigrio 2000, Tenani 2002, Fernandes 2007) Slide 39 the researcher already gave-back the money Slide 40 2. Basic tunes in BP: narrow (informational) focus Two possibilities: main option is different from SEP (Fernandes 2007) the girls beautiful died in-the lake focus Who died in the lake ? Slide 41 the girls beautiful died in-the lake focus Who died in the lake ? Slide 42 2.
