Abstract:
Emotion recognition by analysis of speech signal is a recent area of research. â€˜n-bitâ€™ rank, for some fixed n, of
symbolic dynamics has already been applied in connection with one-dimension signals. However, it is completely a new
approach in connection with distinction of emotions through speech signals. The present paper considers four bit rank of
symbolic dynamics of speech signals in both anger and normal state. It proves that two emotion states are significantly
different from each other.
