In this paper, we present a multiplication table game that automatically detects and recognizes handwritten digits written on the white board. The result of the multiplication of two numbers would not only be displayed on the monitor, but it would be also spoken by the Text To Speech (TTS). The proposed application is divided into three stages: 1) detect a white board; 2) segment candidate regions...
An automated speaker recognition system for home service robots is proposed in this paper. In an uncontrolled environment, a speech classifier should be adaptive to different users and robust to noisy environments. It is usually observed that specific features and classifiers are more appropriate to parts of the problem domain than others; therefore, we propose a self-optimizing approach in which...
Ambient noise caused by room acoustics usually degrades quality and reliability of speech recognition for the service robot application. In this paper, we propose enhancing the robustness of speech recognition for home service robots by combining blind equalization with classification. In particular, the linear predictive code (LPC) is used for feature extraction. The constant modulus algorithm (CMA)...
