Air traffic control communication (ATCC) speech corpora and their use for ASR and TTS development

The paper introduces the motivation for creating dedicated speech corpora of air traffic control communication, describes in detail the process of preparation of corpora for both automatic speech recognition and text-to-speech synthesis, presents an illustrative example of speech recognition system&#x...

Design of Rao-Blackwellized Point-Mass Smoother for Conditionally Linear and Gaussian Models

This paper deals with the state estimation of nonlinear stochastic dynamic systems. Stress is laid on the numerical solution to the functional recursive relations providing conditional probability density functions of the state. In particular, a novel Rao-Blackwellized point-mass smoother with tw...

A unified curvature-driven approach for weathering and hydraulic erosion simulation on triangular meshes

The significant properties of the maximum likelihood (ML) estimate are consistency, normality, and efficiency. While it has been proven that these properties are valid when the sample size approaches infinity, the behavior of an ML estimator when working with small sample sizes is ...

Kontrola výroby a regulační diagramy

Control diagrams belong to the group of preventive tools of quality control. In general, Shewhart control diagrams are used to control production quality but have limited validity in the real world. Therefore, we should also use other procedures that allow effective control of prod...

Decentralised estimation with correlation limited by optimal processing of independent data

Decentralised estimation aims at providing the best combination of multiple estimates. Since the exact solutions are expensive in terms of computation and communication requirements, the mean square error optimality is traded for the bound optimality. Fusion under unknown correlations has been&#x...

Effect of n-3 fatty acids supplementation during life style modification in women with overweight

The marine n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) exert numerous beneficial effects on health, but their potency to defend against development of peripheral insulin resistance of healthy person with overweight remains poorly characterized. We aimed to evaluate&...

Polomnožiny a emergence v umělé inteligenci

The principle of emergence is, today, a key paradigm in the area of the development of systems of artificial intelligence. This article sketches the prospects for tackling emergence in artificial intelligence using Vopěnka’s alternative set theory applied to a model of interaction betwe...

On continuous space word representations as input of LSTM language model

Artificial neural networks have become the state-of-the-art in the task of language modelling whereas Long-Short Term Memory (LSTM) networks seem to be an efficient architecture. The continuous skip-gram and the continuous bag of words (CBOW) are algorithms for learning quality distributed v...

Initial experiments on automatic correction of prosodic annotation of large speech corpora

Most modern speech synthesis systems utilize large speech corpora to learn new voices. These speech corpora usually contain several hours of speech spoken by talented speakers who are able to record such an amount of speech data in a sufficient quality. An appropriate phonetic ...

Experiments with automatic segmentation of liver parenchym using texture description

This paper provides summary of our experiments with automatic segmentation of liver parenchym. It presents methods and classifiers that we used on computer tomography medicine data. In introduction there are a description of our motivation to do this research. Second part contains infor...

Online speaker adaptation of an acoustic model using face recognition

We have proposed and evaluated a novel approach for online speaker adaptation of an acoustic model based on face recognition. Instead of traditionally used audio-based speaker identification we investigated the video modality for the task of speaker detection. A simulated on-lin...

On the impact of labialization contexts on unit selection speech synthesis

This paper presents a study on coarticulatory labialization and the significance of its respecting/violation during selection and concatenation of speech units in the unit selection speech synthesis. The aim of this study is to improve the overall speech quality, especiall...

A way of segmentation of speech recorded simultaneously by two microphones

This paper deals with a problem of segmentation of speech that was recorded by two microphones simultaneously. We suppose that we have a stereo record of an interview between two speakers. The interview is recorded in such a way that each speaker has his/her own micr...

Goubej, Martin , Škarda, Radek , Schlegel, Miloš
Input shaping filters for the control of electrical drive with flexible load

This paper deals with control of flexible mechanical systems. The goal is to modify the input signal in order to minimize the residual vibrations excited during a motion of a system with flexible parts. The filter is designed in the time domain via impulse function analys...

Czech senior COMPANION: wizard of Oz data collection and expressive speech corpus recording and annotation

This paper presents part of the data collection efforts undergone within the projectCOMPANIONS whose aim is to develop a set of dialogue systems that will be ableto act as an artificial "companions"' for human users. One of these systems, being developed in Czech lang...

Local binary pattern based features for sign language recognition

In this paper we focus on appearance features describing the manual component of Sign Language particularly the Local Binary Patterns. We compare the performance of these features with geometric moments describing the trajectory and shape of hands. Since the non-manual component is also...
