This paper proposes interactive game elements for children : contents, design, sound, gesture recognition, and speech recognition. Interactive games for early children must use the contents which reflect the educational needs and the design elements which are all bright, friendly, and simple to use. Also the games should consider the background music which is familiar with children and the narration which make easy to play the games. In gesture recognition and speech recognition, the interactive games must use gesture and voice data which hits to the age of the game user. Also, this paper introduces the development process for the interactive skipping game and applies the child-oriented contents, gestures, and voices to the game.

Use of voice-based interfaces that can interact with users is increasing as AI technology develops. To date, however, most of the research on voice-based interfaces has been technical in nature, focused on areas such as improving the accuracy of speech recognition. Thus, the voice of most voice-based interfaces is uniform and does not provide users with differentiated sensibilities. The purpose of this study is to add a emotional factor suitable for the AI interface. To this end, we have derived emotional factors that should be considered in designing voice interface. In addition, we looked at voice trends that differed from country to country. For this study, we conducted interviews with voice industry experts from Finland and Norway, countries that use their own independent languages.

기존의 조명제어는 주로 밝기의 제어를 목적으로 하였으나 최근에는 스마트폰을 이용하거나 스마트 홈 디바이스를 이용하는 등 다양한 방법으로 조도 및 색온도를 사용자가 직접 조작할 수 있는 형태로 발전하고 있다. 또한 사용자의 감성이나 능률에도 영향을 미칠 수 있는 조명 시스템에 대한 연구도 활발히 진행되고 있다. 그러나 기존의 조명 제어 서비스는 조명의 색과 밝기 제어가 가능하지만 현재의 조명 환경에 대한 적합 여부는 고려되지 않는 경우가 많았다. 본 논문에서는 스마트폰을 이용한 음성 인식 기반의 사용자 맞춤형 조명제어 시스템을 제안한다. 제안 시스템은 사용자가 제공받고 있는 조명의 특성을 스마트폰을 통해 계측하여 확인하고 스마트폰 어플리케이션 기반의 제어 또는 음성인식 기반의 제어를 통해 사용자 맞춤형 조명 서비스를 제공한다.

IT(Information Technology)분야의 발전과 함께 RT(Robot Technology)분야도 21세기의 유망한 첨단기술로 손꼽히고 있다. 현재의 로봇은 그동안 주류를 이루던 산업용 로봇과는 달리 소프트컴퓨팅, 인간친화 인터페이스, 상호작용기술, 음성인식, 물체인식, 사용자 의도파악 등 갖가지 최첨단 기술들이 요구되는 퍼스널 로봇이 각광을 받고 있으며, 특히 오락용, 교육용 로봇들로 대표되는 엔터테인먼트 로봇(Entertainment Robot)분야가 요즘 국내·외에서 활발히 연구되고 있는 실정이다. 엔터테인먼트 로봇은 정형화된 작업만을 하는 것이 아니라 다양한 환경에서 여러 가지 작업을 해야만 한다. 따라서, 장난감 로봇처럼 인간과의 감정대화가 가능한 지능 시스템을 갖춰야만 한다. 그러므로 본 논문에서는 IT분야와 RT분야의 접목으로 시너지 효과를 크게 얻을 수 있는 새로운 기술 개념인 RCP(Robotic Cellular Phone)에 대한 개념을 정의하고, RCP의 기능성 모듈 중 하나인 감성발향 모듈에 대한 기본적인 이론과 실험적 결과를 통하여 로보틱 셀폰의 감성발향 모듈의 우수성을 확인한다.

In this paper, we present a FAES(a Facial Animation with Emotion and Speech) system for speech-driven face animation with emotions. We animate face cartoons not only from input speech, but also based on emotions derived from speech signal. And also our system can ensure smooth transitions and exact representation in animation. To do this, after collecting the training data, we have made the database using SVM(Support Vector Machine) to recognize four different categories of emotions: neutral, dislike, fear and surprise. So that, we can make the system for speech-driven animation with emotions. Also, we trained on Korean young person and focused on only Korean emotional face expressions. Experimental results of our system demonstrate that more emotional areas expanded and the accuracies of the emotional recognition and the continuous speech recognition are respectively increased 7% and 5% more compared with the previous method.

This paper describes a Voice User Interface(VUI) method and a design guideline tool which supports the studies for domestic appliance. This issue covers specification of user requirement and selection of appropriate VUI to represent speech generation. The criteria for paper is interaction design to enhance user engagement. The studies were carried out to measure prototype of domestic appliance such as a refrigerator, a washing machine, a Gimchi refrigerator, an oven range, a dishwasher and an air conditioner. This paper is presented a study of user preferences and suitability. The results of these findings to voice interface design are discussed and it is suggested that VUI guideline and optimal prototyping can provide a useful application tools in the design process.

As the advantages of smart devices based on artificial intelligence and voice recognition become more prominent, Virtual Assistant is gaining popularity. Virtual Assistant provides a user experience through smart speakers and is valued as the most user friendly IoT device by consumers. The purpose of this study is to investigate whether there are differences in people's perception of the key virtual assistant brand voice recognition. We collected tweets that included six keyword form three companies that provide Virtual Assistant services. The authors conducted semantic network analysis for the collected datasets and analyzed the feelings of people through sentiment analysis. The result shows that many people have a different perception and mainly about the functions and services provided by the Virtual Assistant and the expectation and usability of the services. Also, people responded positively to most keywords.

In this paper, we apply several pattern recognition algorithms to emotion recognition system with speech signal and compare the results. Firstly, we need emotional speech databases. Also, speech features for emotion recognition is determined on the database analysis step. Secondly, recognition algorithms are applied to these speech features. The algorithms we try are artificial neural network, Bayesian learning, Principal Component Analysis, LBG algorithm. Thereafter, the performance gap of these methods is presented on the experiment result section. Truly, emotion recognition technique is not mature. That is, the emotion feature selection, relevant classification method selection, all these problems are disputable. So, we wish this paper to be a reference for the disputes.
