Abstract

Studied in this paper study the net cash flow for corporation investment via grey calamity prediction model. Corporation raises enough cash according to the prediction value, and the development of item is ensured, thus reducing the invest risk largely brought about by the cash shortage. The model is effective and the application foreground is broad in cash risk prediction of corporation investment. [ABSTRACT FROM AUTHOR]

30. Speech Emotion Feature Analysis Based on Emotion Fingerprints

Author

Jiang, Yuantao, Deng, Kaifa, and Wu, Chunxue

Abstract

The speech recognition has caught the attention of more and more researchers as the important branch of artificial intelligence. However, speech recognition just can recognize the neutral meaning and ignore the important emotion information. So, this paper proposes an emotion fingerprint extraction algorithm. The speech signal is decomposed by lifting wavelet packets. And combining singular value entropy and sample entropy as the feature vector to characterize the speech time-frequency matrix coefficient. Then adopting the statistical values to extract emotion fingerprints. The experiments show that this algorithm can reflect the emotion information of the speech fully and distinguish several major emotions well.
