Problems solved by technology
Existing fault diagnosis and health monitoring systems mostly use real-time collection of equipment data for interpretation. The system lacks the collection and utilization of voice information in the testing process, and usually makes judgments by manually listening to passwords. Problems due to miscommunication of voice messages

Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] (1), system overview
[0043] The functions of the speech recognition system include speech preprocessing, speech recognition, user-defined thesaurus, speech analysis, and speech result storage and query functions.
[0044] Such as figure 1As shown, a kind of voice-driven testing and issuing password monitoring system provided by the present invention includes N terminal acquisition devices and voice recognition servers, and N is greater than or equal to 1. In actual use, there will be a situation where multiple people issue voice passwords at the same time. When N is greater than 1.
[0045] 1. Terminal collection equipment
[0046] The N terminal collection devices collect externally input voice passwords through microphones, and send the voice passwords to the voice recognition server.
[0047] The microphone of the terminal acq...

The invention relates to a system and method for monitoring test launch command on the basis of voice drive. According to the method, a multithread concurrence model is adopted, and N paths of audio signals corresponding to voice commands in accordance with a preset grammar file structure are circularly monitored; every time it is detected that one path of audio is input, the current moment is recorded as a voice commands receiving moment corresponding to the input of the audio, and then a voice processing sub-thread is started to execute the following steps of (1) preprocessing audio signals,eliminating noise in the audio signals, performing audio segmentation and waveform transformation on the audio signals, extracting a characteristic vector corresponding to each word, utilizing the characteristic vectors to convert the voice commands into text information in combination with a command word library customized by a user, and storing the text information; (2) carrying out semantic analysis on the text information according to the preset grammar file structure, performing word segmentation on the text information, identifying test launch command information, and converting the test launch command information into a state quantity. The method and the system improve the robustness and automation of a test launch process.
Description
technical field [0001] The invention relates to a voice-driven testing and issuing password monitoring system and method, belonging to the technical field of voice recognition. Background technique [0002] Speech recognition means converting the content and meaning of human speech into computer-readable input, such as keystrokes, binary codes, or character sequences. This differs from speaker recognition, which is primarily about identifying and validating the person speaking rather than what is contained in it. The purpose of speech recognition is to allow machines to understand the spoken language of humans, which includes two meanings: the first is to understand word by word instead of converting it into written language; the second is to interpret the commands or requests contained in the spoken language. To understand, to respond correctly, not just stick to the correct conversion of all words. [0003] In the launch test process of the launch vehicle, fault diagnosi...
