Facial Expression Recognition for Speaker Using Thermal Image Processing and Speech Recognition System
نویسنده
چکیده
I investigated a method for facial expression recognition for a human speaker by using thermal image processing and a speech recognition system. In this study, we improved our speech recognition system to save thermal images at the three timing positions of just before speaking, and just when speaking the phonemes of the first and last vowels. With this method, intentional facial expressions of “angry”, “happy”, “neutral”, “sad”, and “surprised” were discriminable with good recognition accuracy. Key-Words: Facial Expression Recognition, Thermal Image Processing, Speech Recognition System, Vowel, Speaker, Discrete Cosine Transformation

Facial Expression Recognition of Speaker Using Vowel Judgment and Features of Thermal Face Image
We developed a method and a system for facial expression recognition of a speaker using vowel judgment and features of a thermal face image. In this study, a speech recognition system saves thermal images at the three timing positions of just before speaking, and just when speaking the phonemes of the first and last vowels. The face direction is estimated to select front-view faces as the targe...

متن کاملSpeaker Adaptation in Continuous Speech Recognition Using MLLR-Based MAP Estimation
A variety of methods are used for speaker adaptation in speech recognition. In some techniques, such as MAP estimation, only the models with available training data are updated. Hence, large amounts of training data are required in order to have significant recognition improvements. In some others, such as MLLR, where several general transformations are applied to model clusters, the results ar...
متن کاملClassification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...
