Chinese and English language speech recognition method and system for civil aviation air-ground call field

Abstract

The invention discloses a Chinese and English language speech recognition method and system for the civil aviation air-ground call field. The Chinese and English language speech recognition method forthe civil aviation air-ground call field includes the steps: acquiring a data set of civil aviation air-ground call speeches, including audio files, annotated texts, a pronunciation dictionary and alanguage model, as a training data set; performing feature extraction on the training data set, and converting the data to obtain a feature vector; performing language recognition training according to the feature vector to obtain a Chinese and English language recognition model; performing speech recognition training according to the feature vector to obtain a Chinese and English speech recognition model; and taking the language recognition model as a front end and taking the speech recognition model as a back end to obtain a Chinese and English language speech recognition method for civil aviation air traffic control. The Chinese and English language speech recognition method or system for the civil aviation air-ground call field can assist a controller to perform air-ground dialogue analysis to guarantee accuracy of speech recognition and improve accuracy of civil aviation air-ground calls.

Description

technical field [0001] The invention relates to the field of intelligent communication, in particular to a Chinese and English language speech recognition method and system aimed at the field of civil aviation land-air communication. Background technique [0002] Due to the rapid development of air transport, general aviation and military traffic, the air traffic control (Air Traffic Control, ATC) system is busy, and the work intensity of air traffic control is high and the working hours are long, which leads to fatigue and lack of energy of the controllers. It is easy to issue inappropriate or even wrong instructions during the call. [0003] Many air accidents worldwide are caused by ground-to-air communication errors. In 1977, the worst air disaster in the history of civil aviation occurred on the island of Tenerife, killing all 583 passengers. The crash was caused by the pilot using improper flight instructions when communicating with the controller. [0004] As an im...

AI Technical Summary

Problems solved by technology

In order to reduce the occurrence of land-air call errors, the International Civil Aviation Organization has continuously improved the terminology specifications for land-air call calls, but flight accidents caused by land-air call errors still continue to occur, which poses a severe test to civil aviation safety.
