摘　　要：Based on the spectrograms analysis and the individual frequency bands of speech under G-force, in this pa-per, a new Mel frequency scale is proposed, and the related MFCC (Mel Frequency Cepstrum Coefficient) is adoptedas the features for recognition of stressed speech under G-force. It is shown from the experiments that the proposedmethod is better than other methods of Mel-based features for stressed speech recognition.Based on the spectrograms analysis and the individual frequency bands of speech under G-force, in this paper, a new Mel frequency scale is proposed, and the related MFCC (Mel Frequency Cepstrum Coefficient) is adopted as the features for recognition of stressed speech under G-force.
