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
establishedbetween130Hzand500Hz,whereasmalespeakerswerebetween90Hz
and 400 Hz. F0 values on Hz were converted into semitones (ST) to ensure the
comparisonofdifferent individuals’ samples.Durationwascalculated inmilliseconds
(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
fundamentalschoollevelwhospeaksBrazilianPortuguesefromPará–Baiãoandthe
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
isolatedbyindividualsandthethreebestrepetitionswereselected.
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).
