The purpose of this work is to evaluate and to compare the acoustic properties of oesophageal voice and voice prosthesis speech production. A group of 14 Italian laryngectomized patients were considered: 7 with oesophageal voice and 7 with tracheoesophageal voice (with phonatory valve). For each patient the spectrogram obtained with the phonation of vowel /a/ (frequency intensity, jitter, shimm...


 This essay seeks to link Terry Eagleton’s work as a novelist and playwright with his over many years, in theory, philosophy, literary criticism. The several pieces discussed here shimmer raw energy, innovative technique, deep grasp of the tangled histories England Ireland. ability both critical creative modes is rare constantly shifting boundaries considered indicate desire carve out gen...

We present an investigation of the representation of voice source aperiodicities in the Multi-Band Excitation (MBE) speech model for the compression of narrowband speech. The MBE model is a fixed-frame based analysis-synthesis algorithm which combines harmonic and stochastic components to reconstruct speech from estimated model parameters. Pitch cycle perturbations, such as jitter and shimmer, ...

The aim of the present study was to investigate the difference between measured spectral and cepstral values of normal adults and those of Amyotrophic lateral sclerosis (ALS) speakers in Korea. Subjects were 8 women with ALS and 20 normal women with no difficulty in physical activities as control group. As the result of independent t-test, measured spectral and cepstral value had significant di...

Tracheoesophageal (TE) speech has been the current preferred treatment for speech rehabilitation after total laryngectomy, but due to the lack of objective evaluation criteria, it is tough to operate a qualitative analysis on the effects of postoperative speech rehabilitation. The present paper advanced an objective evaluation system involving acoustic characteristics parameters such as fundame...

Acoustic models of emotions may benefit from considering the underlying voice production mechanism. This study sought to describe emotional expressions according to physiological variations measured from the inverse-filtered glottal waveform in addition to standard parameter extraction. An acoustic analysis was performed on a subset of the /a/ vowels within the GEMEP database (10 speakers, 5 em...

Acoustic differences between the vowels in filled pauses and ordinary lexical items such as nouns and verbs were examined to know if there was systematic difference of voice-quality. Statistical test of material taken from the Corpus of Spontaneous Japanese showed that, in most cases, there was significant difference of acoustic features like F0, F1, F2, intensity, jitter, shimmer, TL, H1-H2, H...

During conversations, speakers are assumed to provide information about their emotional state. This study is a systematic investigation of the voice characteristics of the emotion of anxiety. For this purpose speech samples of 63 subjects were collected in a situation which induced mild anxiety. On the basis of the acoustic measurements it appears that anxiety affects vocal parameters and showe...
