Speech interpretation method of saturation diving helium based on thesaurus learning

Abstract

The invention relates to a helium voice interpretation method for saturation diving based on lexicon learning. In a system including divers, a correction network and an interpretation network, a lexicon of working languages ​​commonly used in saturation diving operations is established, and the divers read aloud in different environments to generate The supervisory signal and vector signal of the correction network, the correction network learns the helium speech of different divers at different diving depths to obtain the network correction parameters, and corrects the diver’s helium speech to obtain the corrected speech; the interpretation network learns the corrected speech and completes the helium Interpretation of speech. The present invention introduces machine learning into helium speech interpretation by setting divers' individual speech signal characteristics and working language lexicon characteristics in different environments, solves the problem of interpretation of saturation diving helium speech, and reduces the network's requirements for learning samples. Improve the adaptability of the helium voice interpreter at different diving depths, especially suitable for the complete interpretation of helium voices in different diving depth environments.

Description

technical field [0001] The invention relates to helium speech interpretation technology, more specifically to a saturation diving helium speech interpretation method based on lexicon learning. Background technique [0002] The 21st century is the era of marine economy, we will obtain more than 50% of the clean energy and production materials needed by human beings from the ocean. Saturation diving has extremely important application value in the fields of nautical operations, ocean development, military ocean, sea rescue, etc., and is an indispensable part of the development of marine economy. [0003] Due to the particularity of the deep-sea operating environment and work content, many tasks in the ocean cannot be completed by manned deep-sea submersibles or underwater robots. Divers need to go directly into the water and be exposed to deep-sea high-pressure environments using saturation diving techniques. In order to meet the physiological needs of divers in deep-sea high...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing helium voice interpreters for saturation diving at home and abroad are interpreting the helium voice through the helium voice interpreter in the diving chamber and manually adjusting the frequency domain or delay characteristics of the interpreter, which cannot adapt to the depth of saturation diving operations. , and the interpretation effect is not ideal. When the diving depth is greater than 200 meters, the interpretation quality of the helium voice interpreter drops rapidly, especially when the diver’s diving depth is changing, it cannot effectively interpret the diver’s helium voice

Artificial intelligence-based speech interpretation technology for saturation diving helium is currently in its infancy at home and abroad, and practical technical solutions are rarely seen
