Investigou-se a influencia do acento e o preenchimento segmental de unidades prosodicas em dados de fala de duas criancas entre 1;0.4 e 2;1.10 de idade, expostas ao PB falado em Alagoas e Pernambuco. Partiu-se da hipotese de processamento gramatical de direcoes opostas co-ocorrentes: a centripeta segmentando a silaba proeminente e a oposta, centrifuga, destinada aos preenchimentos segmentais das unidades prosodicas. Nas analises esta implicita a hierarquia entre as estruturas constituintes, preconizada pelas fonologias autossegmental (GOLDSMITH, 1995; CLEMENTS; HUME, 1995; MOTA, 1996) e prosodica (NESPOR; VOGEL, 1986; SCARPA, 1997, 1999a; SANTOS; SCARPA, 2005). O predominio de palavras com o padrao de acento troqueu contribuiu para o preenchimento da estrutura silabica e a diferenciacao de classes segmentais na silaba tonica e na pos-tonica, embora o preenchimento tenha ocorrido de forma semelhante nas silabas pre e pos-tonicas sob influencia do pe metrico da palavra-alvo. ******************************************************************** Prosodic unit completion within the early phonological acquisition of Brazilian Portuguese Abstract: The study looked into the influence of accent and segment completion of prosodic units in speech data from two children aged between 1;0.4 and 2;1.10 who had been in contact with BP spoken in Alagoas and Pernambuco. Early hypothesis was that grammatical processing occurred in simultaneous opposite directions: centripetal motion triggering segmentation of the prominent syllable and an opposite centrifugal motion causing segment completion of prosodic units. The analyses imply a hierarchical organization of its constituent structures, an assumption backed by autosegmental (GOLDSMITH, 1995; CLEMENTS; HUME, 1995; MOTA, 1996) and prosodic phonology (NESPOR; VOGEL, 1986; SCARPA, 1997, 1999a; SANTOS; SCARPA, 2005). The prevalence of words having a trochaic stress pattern contributed to syllable structure completion and distinction of segment classes in stressed and post-tonic syllables, although completion in post-tonic and pre-tonic syllables had occurred according to the metrical foot of the target word.

Durante los últimos años se ha llevado a cabo una serie ininterrumpida de estudios en el español de Buenos Aires con el objeto de demostrar la íntima relación existente entre la polifonía enunciativa y la entonación del discurso. Así se ha podido constatar que las formas prosódicas marcadas evocan enunciadores que se plasman en el discurso a través de las melodías del decir. En el presente estudio, se han analizado 10 casos de enunciados articulados con “pero” provenientes de un corpus de 12 registros de conversaciones informales y entrevistas radiales en español de Buenos Aires. En los diez casos, se constató la presencia de rasgos entonativos expresivos así como una fuerza y orientación argumentativa similares. La Teoría de los Bloques Semánticos nos permitió explorar las argumentaciones externas contextuales de estos enunciados. Nos proponemos demostrar que las formas entonativas expresivas en enunciados del tipo “p pero q” acarrean instrucciones semántico-argumentativas similares a las de algunos operadores argumentativos, específicamente los internalizadores. Para corroborar la percepción inicial se utilizó el software de análisis acústico PRAAT. Debido al límite que impone este trabajo, sólo incluimos algunos gráficos representativos., For the last decade there has been an uninterrupted series of studies in the Spanish of Buenos Aires whose purpose is to explore the close connection between intonation and discursive polyphony. It has been possible to demonstrate that prosodically marked forms evoke points of view which are exclusively materialized through the melodies of speech. In the following study, 10 instances of utterances connected with “pero” (but) have been analyzed. These utterances have been obtained from a corpus of 12 recordings consisting of informal conversations and radio interviews. All the cases studied here, display marked intonational features and similar argumentative orientation and force. The Theory of Semantic Blocks allowed us to explore their contextual external argumentations. Through the present study, we seek to demonstrate that the marked or expressive phonological features of utterances “p but q” carry argumentative instructions that resemble those of internalizers. The initial perception was corroborated by means of PRAAT, software of acoustic analysis. Due to the limits that any publication imposes, we only include some of the figures obtained through this software., Facultad de Humanidades y Ciencias de la Educación
