Formant estimation based on temporal synchronous analysis
The accuracy of formant frequency estimation on voiced speech in frame-based linear predictive analysis is affected by the position of the analysis frame relative to the instant of onset of vocal tract excitation. An automatic waveform-dependent point-wise analysis which employs a weighted least-square lattice (WLSL) algorithm to minimise these errors is described here. Experiments on both synt...
متن کاملPitch-synchronous time-scaling for prosodic and voice quality transformations
Current time-domain pitch modification techniques have well known limitations for large variations of the original fundamental frequency. This paper proposes a technique for changing the pitch and duration of a speech signal based on time-scaling the linear prediction (LP) residual. The resulting speech signal achieves better quality than the traditional LP-PSOLA method for large fundamental fr...
متن کاملPitch-synchronous time-scaling for high-frequency excitation regeneration
The goal of bandwidth extension of speech (BWE) is to extrapolate the missing low or high frequency components of the wide-band speech (50-8000 Hz) based entirely on information contained in a narrow-band signal (300-3400 Hz). In this paper we propose a new method for high-frequency regeneration of the excitation signal, using the correlation between the shape of the glottal flow waveform and t...
متن کاملtask-based language teaching in iran: a mixed study through constructing and validating a new questionnaire based on theoretical, sociocultural, and educational frameworks
جنبه های گوناگونی از زندگی در ایران را از جمله سبک زندگی، علم و امکانات فنی و تکنولوژیکی می توان کم یا بیش وارداتی در نظر گرفت. زبان انگلیسی و روش تدریس آن نیز از این قاعده مثتسنی نیست. با این حال گاهی سوال پیش می آید که آیا یک روش خاص با زیر ساخت های نظری، فرهنگی اجتماعی و آموزشی جامعه ایرانی سازگاری دارد یا خیر. این تحقیق بر اساس روش های ترکیبی انجام شده است.پرسش نامه ای نیز برای زبان آموزان ...
A HMM-Based Pitch Tracker for Audio Queries
In this paper we present an approach to the transcription of musical queries based on a hidden Markov model (HMM). The HMM is used to model the audio features related to the singing voice, and the transcription is obtained through Viterbi decoding. We report our preliminary work on evaluation of the system.
