I examine lexical stress and stress shift in contexts of stress clash in Brazilian Portuguese (BP) continuous speech data. I start by investigating whether an automatic speech recognition (ASR) toolkit can detect lexical stress using spectral information, as represented by the Mel Frequency Cepstral Coefficients (MFCCs) of stressed and unstressed vowels. The ASR toolkit was trained using a phonetic dictionary where each entry was labeled for primary stress, a list of phones, transcripts, and a…

ASR Inspired Syllable Stress Detection for Pronunciation Evaluation Without Using a Supervised Classifier and Syllable Level Features

This work proposes to estimate stress markings in automatic speech recognition (ASR) framework involving finite-state-transducer (FST) without using annotated stress markings and segmental information.

On the robustness of some acoustic parameters for signalling word stress across styles in Brazilian Portuguese

The parameters pattern according to stress level is very similar between interview and phrase reading styles, which points to a similar effectiveness of reading and spontaneous styles in uncovering the word stress acoustic correlates in BP.

The Relationship Between Native Speaker Judgments of Nonnative Pronunciation and Deviance in Segmentais, Prosody, and Syllable Structure

This study investigated the relationship between experienced SPEAK Test raters' judgments of nonnative pronunciation and actual deviance in segmentals, prosody, and syllable structure. Sixty reading

Primary Word Stress in Brazilian Portuguese and the Weight Parameter

In this paper, we develop an analysis of primary word stress in Brazilian Portuguese (BP). We evaluate the typological and language-specific arguments that are presented in the literature against the

Acoustic correlates of word stress: A cross-linguistic survey

Abstract The study of the acoustic correlates of word stress has been a fruitful area of phonetic research since the seminal research on American English by Dennis Fry over 50 years ago. This paper

In this account of metrical stress theory, Bruce Hayes builds on the notion that stress constitutes linguistic rhythm - that stress patterns are rhythmically organized, and that formal structures
