Nouns and verbs in the speech signal: Are there phonetic correlates of grammatical category?

Lohmann, Arne 22 November 2024 (has links)
Over the past decades a considerable number of works have observed differences in the phonetic realization of nouns and verbs. The guiding question in most relevant research is whether such differences are caused by grammatical category per se, or are triggered by more general processes of phonetic implementation that impact nouns and verbs differently. Most studies argue for the latter and focus on one particular process or variable, which is advocated to be responsible for the acoustic differences observed. Among the processes mentioned are pre-boundary lengthening, accentuation, and frequency-induced reduction. Due to the focus on monofactorial explanations, an overview and contextualization of the different processes interacting with the noun-verb distinction is yet missing. The present paper aims to fill this gap. This goal is pursed by providing an in-depth discussion of how grammatical category interacts with a number of different processes that affect acoustic realization. To that end results from the literature on the topic are synthesized with new acoustic analyses of noun-verb homophones from spontaneous speech. The analysis shows that differences in acoustic realization between nouns and verbs are caused by the complex interplay of a number of different processes, defying simple, monofactorial explanations.

No. of bitstreams: 1 Jae Keum Oh.pdf: 6453251 bytes, checksum: 44935e77974596a4e82a9c7b7c032ce6 (MD5) Previous issue date: 2010-10-29 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / This project explores the issues of expressivity in speech by analyzing the nature of phonetic-acoustic and perceptive. The goal is to investigate the effects of pauses in the interpretation of four poems from the four main heteronyms of Fernando Pessoa by an announcer-actor. The object of this investigation is the relationship established between sound and meaning in this interpretation. The corpora are composed of a poem by each of the four main heteronyms Fernando Pessoa's Alberto Caeiro, Ricardo Reis, Álvaro de Campos and Fernando Pessoa by himself, recorded on CD. Acoustic Phonetic analysis includes the measurement of the pause using the software Praat. The results show the use of pauses by the speaker-actor according to the poetic text or backronym. The pauses in poetry reading have a role as developer of the architecture of oral interpretation or expression of meaning effects / Este projeto explora a temática da Expressividade na fala por meio de análise de natureza fonético-acústica e perceptiva. O objetivo é investigar os efeitos das pausas na interpretação de quatro poemas dentre os quatro principais heterônimos de Fernando Pessoa por um locutor-ator. O objeto desta investigação é a relação que se estabelece entre som e sentido nessa interpretação. Os corpora são compostos por um poema de cada um dos quatro principais heterônimos de Fernando Pessoa: Alberto Caeiro, Ricardo Reis, Álvaro de Campos e Fernando Pessoa por ele mesmo, gravados em CD. A análise Fonético Acústica compreende a medição da pausa por meio do software Praat. Os resultados mostram o uso das pausas pelo locutor-ator em função do texto poético ou heteronímico. As pausas, em leitura de poesia, têm o papel de colaborador da arquitetura da interpretação oral ou de expressão dos efeitos de sentidos

The theoretical foundation is sustained on the postulates of Camara Jr. (1970 ), Mateus (1982), de Morais Barbosa (1994) and Moraes and Wetzels (1992), concerning nasality in Portuguese, especially in Brazilian Portuguese. The theoretical framework of Acoustic Phonetics is composed mainly by the work of Ladefoged (2003, 2006 and 2007), Ladefoged, Johnson (2008), Mateus et al. (2005), Delgado-Martins (1988), Morais Barbosa (1994), Malmberg (1998), Medeiros (2007), Medeiros et al. (2008) and Sousa, E. (1994). The informants used as subjects in this research, both Brazilian and Portuguese, are people with low education, low turnover, 50 years of age or older. The Brazilian informants were born and lived most of their lives in rural Fortaleza dos Nogueiras; the Portuguese live in the outskirts of Lisbon. The speech data in Brazil are a result of our field research conducted in 2011. The data from Portugal were provided by the Instituto de Linguística da Universidade de Lisboa and form part of the speech collection of ALEPG (Linguistic and Ethnographic Atlas of Portugal and Galicia). The acoustic-phonetic analysis of the data is made through the program of Speech Station by Sensimetrics for visualization of expectograms and to extract measurements of F1 and F2. We present the values of formants 1 and 2 of the oral and nasal vowels and these are compared in order to show what happens with the nasal vowel in relation to the corresponding oral; we highlight the acoustical characteristics of oral and nasal vowels; we show the articulatory triangle of vowels of the informants of the research highlighting the contours the vowels assume in articulation and the frequency bands in which each vowel stands. Finally, we carry out a comparative investigation of oral and nasal vowels in these two varieties of Portuguese. / Este trabalho apresenta uma análise fonético-acústica das vogais orais e nasais do português brasileiro, mais especificamente da comunidade de fala de Fortaleza dos Nogueiras, Maranhão e do português europeu, em alguns dados de fala da região de Lisboa, Portugal. O embasamento teórico pauta-se nos postulados de Camara Jr. (1970), de Mateus (1982), de Morais Barbosa (1994) e de Moraes e Wetzels (1992), acerca da nasalidade na língua portuguesa, especialmente, no português brasileiro. O referencial teórico de Fonética Acústica compõe-se, principalmente, pelos trabalhos de Ladefoged (2003, 2006 e 2007), Ladefoged; Jonhson (2008), Mateus et al. (2005), Delgado-Martins (1988), Morais Barbosa (1994), Malmberg (1998), Medeiros (2007), Medeiros et al. (2008) e Sousa, E. (1994). Os informantes sujeitos desta pesquisa, tanto brasileiros como portugueses, são pessoas com baixa escolaridade, baixa rotatividade, que têm a partir de 50 anos de idade. Os brasileiros nasceram e viveram a maior parte de suas vidas na zona rural de Fortaleza dos Nogueiras; os portugueses são moradores do entorno de Lisboa. Os dados de fala do Brasil são resultado de nossa pesquisa de campo realizada em 2011. Os de Portugal foram-nos cedidos pelo Instituto de Linguística da Universidade de Lisboa e fazem parte do acervo de fala do ALEPG (Atlas Linguístico e Etnográfico de Portugal e da Galiza). A análise fonético-acústica dos dados é feita por meio do programa Speech Station da Sensimetrics, para a visualização dos expectogramas e para a extração das medidas de F1 e de F2. Apresentam-se os valores dos formantes 1 e 2 das vogais orais e nasais e estes são comparados com o intuito de mostrar o que acontece com a vogal nasal em relação à correspondente oral; evidenciam-se quais as características acústicas das vogais orais e nasais; apresenta-se o triângulo articulatório das vogais desses informantes da pesquisa com evidência para os contornos que elas assumem na articulação e para as faixas de frequência em que cada vogal se posiciona. Por fim, realiza-se uma investigação comparativa das vogais orais e nasais nessas duas variedades da língua portuguesa.
