Efficient Speech Synthesis System using the Deterministic plus Stochastic Model
نویسندگان
چکیده
In this paper, a high-quality concatenative synthesis system using the deterministic plus stochastic model of speech is described, in which the prosodic modifications are performed by means of very simple and efficient operations, as we reported in a previous work [11]. In particular, pitchsynchrony is not necessary, and linear interpolations substitute other types of estimation. The method for the concatenation of units has been improved in order to avoid waveform and spectral mismatches.

Voice quality transformation using an extended source-filter speech model
In this paper we present a flexible framework for parametric speech analysis and synthesis with high quality. It constitutes an extended source-filter model. The novelty of the proposed speech processing system lies in its extended means to use a Deterministic plus Stochastic Model (DSM) for the estimation of the unvoiced stochastic component from a speech recording. Further contributions are t...
متن کاملOn glottal source shape parameter transformation using a novel deterministic and stochastic speech analysis and synthesis system
In this paper we present a flexible deterministic plus stochastic model (DSM) approach for parametric speech analysis and synthesis with high quality. The novelty of the proposed speech processing system lies in its extended means to estimate the unvoiced stochastic component and to robustly handle the transformation of the glottal excitation source. It is therefore well suited as speech system...
متن کاملA Pitch-Asynchronous Simple Method for Speech Synthesis by Diphone Concatenation using the Deterministic plus Stochastic Model
One of the most common approaches to speech synthesis is the concatenation of diphones, extracted from a previously recorded database. The prosodic parameters of the recorded speech fragments have to be adapted to the specifications of the new utterances to be synthesized. In this paper, the deterministic plus stochastic model of speech is used to modify and smoothly concatenate the analyzed di...

The optimal reactive power dispatch (ORPD) is a very important problem aspect of power system planning and is a highly nonlinear, non-convex optimization problem because consist of both continuous and discrete control variables. Since the power system has inherent uncertainty, hereby, this paper presents both of the deterministic and stochastic models for ORPD problem in multi objective and sin...
متن کاملA generalized super-efficiency model for ranking extreme efficient DMUs in stochastic DEA
In this current study a generalized super-efficiency model is first proposed for ranking extreme efficient decision making units (DMUs) in stochastic data envelopment analysis (DEA) and then, a deterministic (crisp) equivalent form of the stochastic generalized super-efficiency model is presented. It is shown that this deterministic model can be converted to a quadratic programming model. So fa...
