In contrast to widely used waveform concatenation methods, the presented approach to speech synthesis relies on a parametric analysis–re-synthesis technique, where the features extracted in the analysis stage are modeled by hidden Markov models (HMMs). Many important improvements in the last decade have helped this approach to reach impressive performance. Additionally, its inherent flexibility...

Segmental evaluation of HTS HTS is a parametric speech synthesis system based on the use of Hidden Markov Models (HMM). HTS is now widely used but very few studies have been conducted to analyze the influence of parameters on the quality of the synthetic speech. The aim of this paper is to provide an objective evaluation of the quality of the synthetic speech produced by HTS in order to assess ...

This paper describes the Text-to-Speech (TTS) systems presented by the Buceador Consortium in the Blizzard Challenge 2011 evaluation campaign. The main system is a concatenative hybrid one that tries to combine the strong points of both statistical and unit selection synthesis (i.e. robustness and segmental naturalness respectively). The hybrid system has reached results significantly above ave...

Our purpose is to evaluate the efficiency of MPEG-7 basis projection (BP) features vs. Mel-scale Frequency Cepstrum Coefficients (MFCC) for speaker recognition in noisy environments. The MPEG-7 feature extraction mainly consists of a Normalized Audio Spectrum Envelope (NASE), a basis decomposition algorithm and a spectrum basis projection. Prior to the feature extraction the noise reduction alg...

background: since psychological tests such as questionnaire or drawing tests are almost qualitative, their results carry a degree of uncertainty and sometimes subjectivity. the deficiency of all drawing tests is that the assessment is carried out after drawing the objects and lots of information such as pen angle, speed, curvature and pressure are missed through the test. in other words, the ps...

The wireless power terminals are deployed in harsh public places and lack strict control, facing security problems. Thus, they faced with problems such as illegal counterfeit terminal access, unlawful control of connected terminals, etc. intrusion detection system based on machine learning artificial intelligence significantly improve the side’s abnormal capacity. In this article, we aim at ide...

Light emitters in the vicinity of a hyperbolic metamaterial (HMM) show range quantum optical phenomena from spontaneous decay-rate enhancement to strong coupling. In this study, we integrate monolayer molybdenum disulfide (${\mathrm{Mo}\mathrm{S}}_{2}$) emitter near-field region HMM. The ${\mathrm{Mo}\mathrm{S}}_{2}$ has $A$ and $B$ excitons, which emit red visible spectrum. We find that excito...

Whilst several examples of segment based approaches to language identification (LID) have been published, they have been typically conducted using only a small number of languages, or varying feature sets, thus making it difficult to determine how the segment length influences the accuracy of LID systems. In this study, phone-triplets are used as crude approximates for a syllable-length sub-wor...
