Speech analysis and synthesis using an auditory model
Many traditional speech analysis/synthesis techniques are designed to produce speech with a spectrum that is as close as possible to the original. This may not be necessary because the auditory nerve is the only link from the auditory periphery to the brain, and all information that is processed by …

Hypernasal Speech Analysis via Emperical Mode Decomposition and the Teager-Kasiser Energy Operator
In the area of speech science, one particular problem of importance has been to develop a clear method for detecting hypernasality in speech. For speech pathologists, hypernsality is a critical diagnostic used for judging the severity of velopharyngeal (nasal cavity/mouth separation) inadequacy in …

SPONTANEOUS SPEECH ANALYSIS FOR DETECTING MILD COGNITIVE IMPAIRMENT AND ALZHEIMER’S DISEASE IN THAI OLDER ADULTS
… in language-based tests, especially spontaneous speech tasks. Three spontaneous speech tests were developed in this study, including Thai Picture description (TPD), Thai Story Recall (TSR), and Semi-structured Interview for Thai (SIT) Ninety-eight Thai older adults underwent screening tests and …

Estimation of glottal source features from the spectral envelope of the acoustic speech signal
Speech communication encompasses diverse types of information, including phonetics, affective state, voice quality, and speaker identity. From a speech production standpoint, the acoustic speech signal can be mainly divided into glottal source and vocal tract components, which play distinct roles …

Diphone Speech Synthesis Based on a Pitch-Adaptive Short-Time Fourier Transform
… of this work is to investigate a new method of speech synthesis from phonetic specifications. The investigation includes the design, computer simulation, and subjective evaluation of a speech analysis-synthesis system. The method is new in the sense that it utilizes two novel analytical …

Towards a declamatory performance in Schubert Lieder
… poems ‘Erster Verlust’ and ‘Geistes Gruß.’ PRAAT speech analysis software was used to analyse the recordings. The participants’ use of stress, emphasis and rubato was extrapolated and used (in combination with the historical evidence) to speculatively recreate several declamatory performances of …

Toward a social signaling framework : activity and emphasis in speech
… pitch, speaking rate, and other non-linguistic speech features are crucial aspects of human spoken interaction. In this thesis, we separate these speech features into two categories -- vocal Activity and vocal Emphasis -- and propose a framework for classifying high-level social behavior …

Autoimagem em hanseníase: influências na participação social
… categorized and treated according to the speech analysis. The results point inferences and impairment of self-image and social participation of the subjects. Understand the subjective and psychosocial conditions of individuals affected by leprosy enables the improvement of health …

Probabilistic generative modeling of speech
Speech processing refers to a set of tasks that involve speech analysis and synthesis. Most speech processing algorithms model a subset of speech parameters of interest and blur the rest using signal processing techniques and feature extraction. However, evidence shows that many speech parameters …

Automatic Detection of Landmark Acoustic Cues in Human Speech
… of the eight landmark acoustic cues in human speech. Landmarks are key articulatory events, produced as a result of minimal vocal tract constriction (e.g., vowels and glides) or closures and releases in the oral region (e.g., nasal, fricative, and stop consonants). A complete landmark …

Correlations Between Vowel Lengths and Emotion in Narratives
… between emotion and vowel length in spontaneous speech, specifically during narratives. It is hypothesized that during emotionally-laden speech, vowel length will be longer in duration than when in non-emotional speech. Data is drawn from the Univerisity of California, Santa Barbara linguistic …

Processing Methods for the Detection of Landmark Acoustic Cues
This paper presents work on an aspect of a new speech analysis system for lexical access, which is based on the concept of individual acoustic cues in the speech signal such as Landmarks, which are abrupt changes in the spectrum due to articulatory events associated with vowels and consonants. It …

Consonant landmark detection for speech recognition
… of abrupt acoustic discontinuities in the speech signal, which constitute landmarks for consonant sounds. Because a large amount of phonetic information is concentrated near acoustic discontinuities, more focused speech analysis and recognition can be performed based on the landmarks. Three …
