The exact pitch(fundamental frequency) extraction is important in speech signal processing like speech recognition, speech analysis and synthesis. However the exact pitch extraction from speech signal is very difficult due to the effect of formant and transitional amplitude. So in this paper, the pitch is detected after the elimination of formant ingredients by flattening the spectrum in freque...

Recent work has identified the physical features of smiles that accomplish three tasks fundamental to human social living: rewarding behavior, establishing and managing affiliative bonds, and negotiating social status. The current work extends the social functional account to laughter. Participants (N = 762) rated the degree to which reward, affiliation, or dominance (between-subjects) was conv...

In the present study Dutch vowel formant characteristics of laryngectomized tracbeoesophageal speakers are investigated.. Both vowels in CV nonsense syllables (/al, Iii, and /u/), and vowels of stressed syllables in read-aloud text are studied. It appeared that in the nonsense syllables the first formants were comparable to those ·of normal speakers, but that the second formants were higher tha...

This study attempts to extend the line of research on using body size projection theory to account for emotional speech. It is predicted by the theory that anger is expressed by projecting a large body size with low pitch, rough voice and long vocal tract; happiness is expressed by projecting a small body size with high pitch, breathy voice and short vocal tract. Ten native speakers of Mandarin...

In this paper, timbre of stringed instrument is analyzed and the timbre sound is synthesized. Timbre is familiar and looks well known, but it has been unknown even now what an essential factor is. And it is the most important factor for human to distinguish sounds with the same duration, loudness and pitch. The formant structure model for keeping the same timbre is proposed in this paper. The s...

PURPOSE Natural speech comes with variation in pitch, which serves as an important cue for speech recognition. The present study investigated older listeners' dynamic pitch perception with a focus on interindividual variability. In particular, we asked whether some of the older listeners' inability to perceive dynamic pitch stems from the higher susceptibility to the interference from formant c...

The chronical dysphony is the result of neural, structural or pathological effects on the vocal cords or larynx and it causes undesirable changes in the quality of speech. This paper presents a Mixed Excitation Linear Prediction (MELP) based system that reconstructs normally phonated speech from dysphonic speech, while preserving the individuality of the patient. The proposed system can be used...
