摘要： Disclosed are a self-attention-based speech quality measuring method and system for real-time air traffic control, including following steps: acquiring real-time air traffic control speech data and generating speech information frames; detecting the speech information frames, discarding unvoiced information frames of the speech information frames, generating a voiced long speech information frame; performing mel spectrogram conversion, attention extraction and feature fusion on the long speech information frame to obtain a predicted mos value.

摘要： An evaluation method and system of an air traffic control (ATC) speech recognition system are provided, the method includes: S1, obtaining, grading and inputting ATC speech data; S2, constructing an evaluation index system; S3, determining weights of utility layer indexes and support layer indexes under different levels ATC speech data; S4, calculating a utility layer score and a support layer score, and adding the scores of the utility layer and the support layer to obtain comprehensive scores of the utility layer and the support layer; S5, determining, weights of the utility layer and the support layer; S6, adding a product of the utility layer weight with the utility layer comprehensive score and a product of the support layer weight with the support layer comprehensive score to obtain a comprehensive score of the speech recognition system; and S7, determining a level of the recognition performance of the speech recognition system.
