Research on Intelligent Information Collection of Business Negotiation System based on Speech Rate Change Recognition Algorithm

This paper conducts the research on intelligent information collection of business negotiation based on speech rate change recognition algorithm. The overall impact of speech speed on pitch is that the pitch decreases at a slow speed, which is mainly reflected in the lowering of the lower line of the tonal range, which is a more important factor leading to the expansion of the tonal range. A fast speech rate leads to a narrowing of the tonal range, and a narrow tonal range will inevitably lead to a decrease in the degree of distinction between tones and the convergence of the four tones. With this prior information, the designed model is selected to be the Naive Guassian model to construct the efficient algorithm of the model. The negotiation system is selected to be the testing scenario. Through the testing on the different aspects, the performance is validated.
