Significance Of Vowel Onset Point For Speech Analysis

by S. R. Mahadeva Prasanna, Suryakanth V. Gangashetty, B. Yegnanarayana - in Signal Processing and Communications (Biennial Conf., IISc , 2001
"... In this paper we discuss the significance of Vowel Onset Point (VOP) for speech recognition in particular, and for accurate speech analysis in general. Vowel onset point is the instant at which the vowel part starts in a ConsonantVowel (CV) utterance. The syllable-like CV utterances are basic units ..."

Begin-End Detection Using Vowel Onset Points

by Mahadeva Prasanna Jinu, R. Mahadeva Prasanna, Jinu Marjam Zachariah, B. Yegnanarayana
"... This paper proposes a method for detecting begin and end points of a speech utterance using the knowledge of Vowel Onset Points (VOPs). VOP is defined as the instant at which the onset of vowel takes place. An algorithm for VOP detection in continuous speech is discussed. VOP helps in overcoming the ..."

Detection of Vowel Onset Point Events u

by S. R. Mahadeva Prasanna
"... This paper proposes a method for the detection of Vowel On-set Point (VOP) events in speech using excitation information. VOP event is defined as the instant at which the onset of vowel takes place. For syllable-like units such as Consonant Vowel (CV) type, VOP event is the instant at which the cons ..."

1Duration modification using Glottal Closure Instants and Vowel Onset Points

by K. Sreenivasa, Rao Member, B. Yegnanarayana, Senior Member
"... This paper proposes a method for duration (time scale) modification using Glottal Closure Instants (GCI, also known as instants of significant excitation) and Vowel Onset Points (VOP). In general, most of the time scale modification methods attempt to vary the duration of speech segments uniformly o ..."

Shapes of the Power Spectrum of Intermittent Turbulence near Its Onset Point

by Kazuhisa Shobu, Tomoaki Ose, Hazime Morl , 1983
"... A general theorY of shapes of the power spectrum of intermittent turbulence is developed from a phenomenological point of view by assuming that bursts at different times are statistically indeperident of each other. It is found that bursts in phase and amplitude give shapes of different types. Near ..."
Abstract - Add to MetaCart
the onset point, the spectrum consists of a number of Lorentzian lines with equal spacing. If the fluctuation of phase jumps by bursts is smaIl, then the envelope of the Lorentzian lines obeys the power law 1 / Iw- wol ' or 1/lw-woI2 in a small frequency-region around the eigenfrequency Wo

Automatic Vowel Onset Point Detection Based on Auditory Frequency Response

by Xian Zang, Hagtae Kim, Kil To Chong
"... Abstract This paper presents a vowel onset point (VOP) detection method based on the human auditory system. This method maps the “perceptual ” frequency scale, i.e. Mel scale onto a linear acoustic frequency, and then establishes a series of Triangular Mel-weighted Filter Bank simulate the function ..."

P-Wave Onset Point Detection for Seismic Signal Using Bhattacharyya Distance

by Bikash Ch, Ra Sahana, M. M Choudhary, Bikash Chandra Sahana, M. M Choudhary
"... In seismology Primary p-wave arrival identification is a fundamental problem for the geologist worldwide. Several numbers of algorithms that deal with p-wave onset detection and identification have already been proposed. Accurate p- wave picking is required for earthquake early warning system and de ..."
