Thispaperreferstothefindingsof(Lemos2015)regardingtheacousticanalysis

– indistinguishing themodal intonationof thePortuguese languagespoken inBaião

(PA).4 For this study in particular, we decided to demonstrate a specific dialectal

prosodicvariationofdeclarativeandinterrogativemodalities.Weobservedintonation

patternsofphrasalmodalities,takingintoaccountthedifferenttypesofphrases(AP,

NPandPP), lexical stress (proparoxytone, paroxytoneandoxytone), schooling social

variables(elementaryandhighschoollevels),andgender(maleandfemale).Ourmain

goalwas toverify theperformanceof thephysicalparameterof F0 indistinguishing

thetargetmodalitiesinvestigatedbytheAMPERproject.Forthisreason,weobserved

the F0 performance, relating it to the previously mentioned social and linguistic

variablespresentintheAMPERcorpus.

TodemonstratetheF0roleindistinguishingthephrasalmodalitiesinBaião(PA),

we selected from (Lemos 2015) some speech samples of four native speakers, two

malesandtwofemales,agedabove30andwithdifferentschoolinglevels(elementary

andhighschool).

To foster better understanding of the performed analysis, this work has been

structured as follows: in the introductory section, we present an overview of our

research; in section 2, we show the source of the analyzed data (Lemos 2015); in

section 3,we describe themethodology adopted for data analysis; in section 4,we

Aspreviously referred, thedataused in thepresentpaperwere selected from

(Lemos 2015), who produced the first prosodic description of Brazilian Portuguese

(henceforth BP) variation spoken in the city of Baião, located in the north of Brazil,

within the Amazon region. The relevance of the data is related to historical, social,

culturalandgeographicaspectsofBaião, regarded in thispaperwith thepurposeof

buildingthespeakers’profiles.Following,wepresentabriefoverviewoftheresearch

Acousticparameters,whichweretakenintoaccountduringtheacousticanalysis

itself,were the sameas those controlledby theAMPERproject coordination,which

are: F0, duration and intensity. Lemos (2015) used the mean of the acoustic

parameters of the three best repetitions of each sentence and target modality,

comprised in 0.txt files generated by the MatLab interface. A pitch scale for each

speakerwasestablished.Asshownontable1above,femalespeakershadascalepitch

and 400 Hz. F0 values on Hz were converted into semitones (ST) to ensure the

(ms)andintensityindecibels(dB).

AccordingtotheoutcomesobservedbyLemos(2015),F0isadeterminantfactor

3.Methodology

TheresearchcarriedoutinBaião,followedthesamecriteriaadoptedby(Lemos

2015)explainedintheprecedingsectioninwhatconcernsspeakers’selectionanddata

treatment.

In order to build up the corpus of this paper, we selected 21 out of the 66

sentences of the AMPER-POR corpus in both target intonational modalities –

declarative and yes/no questions.We analyzed data from four speakers, twomales

(BF92 and BF94) and two females (BF91 and BF93),whose profiles are described in

Table 1. As the target of the acoustic analysis consists in the last word of the final

phraseofthesentence,andaseachselectedsentencecontainsarepresentativestress

inthenucleusofitsphrase,wedecidedtodescribethemintable2below.

In more specific terms, data have been recorded in the speaker-informants’

houses where they were asked to repeat the 42 sentences (21 declarative and 21

interrogative)fromthecorpus,sixtimeseach,randomlywithnointerruptionuntilthe

last one. A mono and headed tape recorder was used to capture the audio and a

notebookwasusedtoprojecttheimagesinaPowerPointprogram.

Inreferencetodatatreatment,sentenceswerelabeledinordertoidentifyeach

speaker.For instance,asentence labeledBF91bwta17 identifiesa femalespeakerat

sentence is identified as declarative in first repetition [O pássaro nadador gosta do

Renato ‘The swimming bird likes Renato’]. After codifying the sentences, files were

For the instrumental analysis procedures, two computational programs were

used:(1)Matlab–asithasspecificapplicationsdevelopedbyAntonioRomanoforthat

Although it was possible to establish a distinctive pattern of the phrasal

4.3CurvepatternofF0foroxytonestresspattern

The analysis that took into account the oxytone stress pattern showed a very

close intonational pattern for the two target modalities. In both cases, an upward

movement of the curve towards the stressed syllable that occupies the final word

positionwasregistered,asFigure4showsbelow:

According to the analysis here undertaken, eight patterns of F0 curve were

identified,oneforeachtargetmodalitycontainingasortof lexicalstressonthefinal

phrase position. Only the yes/no question sentences with proparoxytone words

showed three distinctive patterns. The only difference that might be observed in

relation to a possible F0 movement that distinguishes both modalities would be a

higher movement on the final part of the stressed syllable on yes/no question

modality.Broadlyspeaking,thedescriptionsfromthePortugueselanguagecarriedout

bytheAMPERteamintheNorthofBrazilhaveconfirmedthemainhypothesisposed

bytheproject.Thatistosay,themostmeaningfulvariationsoftheacousticparameter

of F0 occur in the last stressed syllable of the nominal phrases in declarative and

interrogative clauses according to the studies developed by Remédios (2013), Brito

(2014), Guimarães (2013), Castilho (2009), Santo (2011), FreitasNeto (2013), Lemos

(2015)andCosta(2015).
