Source-filter separation of speech signal in the phase domain
Deconvolution of the speech excitation (source) and vocal tract (filter) components through log-magnitude spectral processing is well-established and has led to the well-known cepstral features used in a multitude of speech processing tasks. This paper presents a novel source-filter decomposition based on processing in the phase domain. We show that separation between source and filter in the l...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولRobust Source-Filter Separation of Speech Signal in the Phase Domain
In earlier work we proposed a framework for speech sourcefilter separation that employs phase-based signal processing. This paper presents a further theoretical investigation of the model and optimisations that make the filter and source representations less sensitive to the effects of noise and better matched to downstream processing. To this end, first, in computing the Hilbert transform, the...
متن کاملSignal separation for robust speech recognition based on phase difference information obtained in the frequency domain
In this paper, we present a new two-microphone approach that improves speech recognition accuracy when speech is masked by other speech. The algorithm improves on previous systems that have been successful in separating signals based on differences in arrival time of signal components from two microphones. The present algorithm differs from these efforts in that the signal selection takes place...
متن کاملWavelet analysis of speech signal
This paper concerns the issue of wavelet analysis of signals by continuous and discrete wavelet transforms (CWT – Continous Wavelet Transform, DWT – Discrete Wavelet Transform). The main goal of our work was to develop a program which, through the CWT and the DWT analyses, would obtain graph of time-scale changes and would transform it into the spectrum, that is a graph of frequency changes. In...
