F1 and Spectral Correlates of Secondary Stress in Brazilian Portuguese
Vowel opening and spectral emphasis are investigated as possible acoustic correlates of secondary stress in Brazilian Portuguese. F1 and energy difference between frequency bands were measured for vowel /a/ in fiveand six-syllable stress groups. Results for F1 indicate greater opening for vowels in initial and stressed positions. As for the spectral feature, relative emphasis in bands B2 (0.5 t...
متن کاملSecondary stress in Brazilian Portuguese: the interplay between production and perception studies
This paper reports experiments on speech production showing that secondary stress in Brazilian Portuguese (BP) can be best described as phrase-initial prominence cued by greater duration and pitch accent excursion in initial position. It also reports a perception experiment in which clicks were associated to consecutive V-to-V positions in stress groups. Mean click detection RTs are gradient, b...
متن کاملIntensity and fundamental frequency control in tracheoesophageal voice.
Tracheo-oesophageal voice prostheses are currently widely used following total laryngectomy. Data on maximum phonation time and spectrum have been studied by various Authors and are well known. On the contrary, intensity and fundamental frequency control have received little attention. Intensity and fundamental frequency play an important role in the prosodic aspects of speech. Fundamental freq...
متن کاملNeural correlates of lexical stress: mismatch negativity reflects fundamental frequency and intensity
Neural correlates of lexical stress were studied using the mismatch negativity (MMN) component in event-related potentials. The MMN responses were expected to reveal the encoding of stress information into long-term memory and the contributions of prosodic features such as fundamental frequency (F0) and intensity toward lexical access. In a passive oddball paradigm, neural responses to changes ...
متن کاملStress assignment in Brazilian Portuguese: a usage-based approach
The major debate on primary stress assignment in Brazilian Portuguese (BP) concerns whether it is lexically given or predictable by a set of principles. This paper presents a contribution to this debate by suggesting a usage-based approach to stress assignment in BP. It is argued that stress assignment is better accounted for as the result of generalizations over exemplars, and these generaliza...
