INTRODUCTION

Studies show that Portuguese spoken in Brazil and Portugal differs in several linguistic levels^{( 1}1. Silva AS. Integrando a variação social e métodos quantitativos na investigação sobre linguagem e cognição: para uma sociolinguística cognitiva do português europeu e brasileiro. Rev Est Ling. 2008;16(1):49-81. ⁾, including semantic, morphosyntactic, phonetic/phonological, among others. The differences between Brazilian Portuguese (BP) and European Portuguese (EP) go beyond the segmental level, reaching the prosodic level^{( 2}2. Frota S, Vigário M. Aspectos de prosódia comparada: ritmo e entoação no PE e no PB. In: Actas do XV Encontro da Associação Portuguesa de Linguística; 2000 Set 29-Out 01; Braga. Braga: APL; 2000; 533-55. ^{, 3}3. Cruz M.

It is questioned, then, if the speech language fluency patterns, the aim of this study, would also present their particularities in EP and BP.

The parameters commonly used to objectively assess speech fluency are the common dysfluencies, stuttering dysfluencies, speech discontinuity percentage or total rupture rate, percentage of stuttered syllables, and speech rate^{( 4}4. Andrade CRF, Martins VO. Influencia del sexo y el nivel educativo en la fluidez del habla en personas adultas. Revista de Logopedia Foniatría y Audiología. 2011;31(2):74-81. ⁾; the last one is also called elocution and/or articulation rate^{( 5}5. Celeste LC, Reis C.

Such parameters have been researched in Brazil, designing a normative profile for fluent speakers^(4,7,8) and characterizing different communication disorders^{( 5}5. Celeste LC, Reis C.

However, studies describing the profile of EP speech language fluency are required^{( 3}3. Cruz M. Gaguez: em busca de um padrão prosódico e entoacional dissertação. Lisboa: Faculdade de Letras da Universidade de Lisboa; 2009. ⁾.

Assessing fluency is extremely relevant to provide parameters on the effectiveness of language, rather than only diagnosing stuttering⁽¹²⁾ and other communication disorders. In this sense, studies providing reference values for fluent speakers, considering the particularities of each language, are important to increase the accuracy of diagnosis^{( 7}7. Martins VO. Variação da fluência da fala em falantes do Português Brasileiro: quatro estudos [tese]. São Paulo: Faculdade de Filosofia, Letras e Ciências Humanas da Universidade de São Paulo; 2007. ⁾.

The objective of this work was to compare fluency parameters of native adult speakers of BP and EP.

METHODs

This research was considered and approved by the research ethics committee of the Universidade Federal de Minas Gerais under the protocol CAAE 01460612.4.0000.5149, authorized by the Department of Speech Language Therapy of the Universidade do Algarve (Portugal). All participants signed the informed consent term.

This study comprised melhor included 76 subjects of both gender, with no distinction as for race and color, with 38 of them living in the metropolitan region of Belo Horizonte (the capital of the state of Minas Gerais, Brazil)and 38 of them living in the city of Faro (District capital of Faro, in the region of Algarve, Portugal). All subjects were aged between 18 and 29 years.

As an exclusion criteria, the participants could not present personal and/or family complaints of stuttering and/or communication or health deficits that would impair speech language production.

The methodology used to collect and analyze the speech samples considered the following fluency parameters: rupture typology (common dysfluencies: hesitation, interjection, revision, repetition of words and/or segment and/or phrase, and unfinished word; stuttering dysfluencies: repetition of syllables and/or sounds, prolongations, blocking, pause, and intrusion of sound and/or segment); speech rate, in words per minute; and rupture frequency (speech discontinuity percentage and stuttering dysfluencies)^{( 13}13. Andrade CRF. Protocolo para avaliação da fluência da fala. Pró-Fono. 2000;12(2):131-4. ⁾.

A descriptive analysis of the data was performed, calculating values such as the median, mean, and standard deviation. To analyze the independence between the studied groups, we used the χ²-test. To compare the medians, we used the nonparametric Mann-Whitney test. A significance level of 5% was considered.

RESULTS

In relation to the typology of dysfluencies, Table 1 shows the values found for BP and EP, as well as their qualitative distribution.

Speakers of both groups were compared for each dysfluency typology. The variable "hesitation" presented a significant difference (p=0.006), with higher median to the EP speakers (9.0 versus 7.0). The variables "segment repetition" and "sound repetition" also presented significant difference (p=0.005 and p=0.048, respectively). Despite the medians being the same (less than zero), they do not distribute equally among the countries, with higher values for the BP speakers.

The results and the comparison of parameters of the fluency profile are shown in Table 2.

DISCUSSION

This study raised the speech fluency profile of a group of young adult speakers of the BP variant spoken in Minas Gerias (variante mineira) and a group of young adult speakers of the EP variant spoken in Algarve (variante algárvia).

As for the total number of common and stuttering dysfluencies, both BP and EP presented results close to those described in the literature^{( 4}4. Andrade CRF, Martins VO. Influencia del sexo y el nivel educativo en la fluidez del habla en personas adultas. Revista de Logopedia Foniatría y Audiología. 2011;31(2):74-81. ^{, 14}14. Martins VO, Andrade CRF. Perfil evolutivo da fluência da fala de falantes do português brasileiro. Pró-Fono R Atual Cient. 2008;20(1):7-12. ⁾. Despite not being quantitatively different, a qualitative difference was observed in the typology of the dysfluencies: in BP, the review, the unfinished word, and the segment repetition were the most often found dysfluencies, whereas EP speakers used hesitation and word repetition more often.

Due to the reduced number of informants in this research, which figures as an initial attempt to raise questions regarding the variability between BP and EP, it is suggested that a deeper study on the typology of dysfluencies should be conducted to better clarify this particularity. However, while the fluency profile of EP adults is not established, the normality values of the six parameters of fluency may be used in the assessment of these individuals.

Regarding the speech rate, EP speakers present higher rates than BP ones only when it comes to words per minute, without statistical difference as for syllables per minute. One of the possible explanations for this difference is the qualitative distribution of the dysfluencies: in BP, more review dysfluencyis observed. In a study on the dysfluency of review, the authors agreed that there was a decrease in speech rate in the moment of pronunciation of this dysfluency^{( 8}8. Delfino A, Magalhães JO. Estudo prosódico das disfluências de reparo. ReVEL. 2010;8(15):181-207. ⁾, which could, in relation to segmental and suprasegmental levels, influence this parameter. Another explanation would be the high standard deviation, a fact observed in several studies on speech rate^{( 5}5. Celeste LC, Reis C.

Although studies that considered the measure syllable per minute presented results with some variation, in BP we considered that these values may vary between 202.9 and 247.6^{( 4}4.

CONCLUSION

The parameters analyzed in this study on fluency profile point toward a tendency for similarity between BP and EP. However, it was observed that the speech rate of EP speakers is higher than that of BP speakers in words per minute. Despite the number of common dysfluencies being similar, their qualitative distribution differentiates the languages from one another. In BP, we found a higher frequency of reviews, unfinished words, and segment repetition, whereas EP speakers present more hesitation and repetition of words.
