Problems solved by technology

[0005] The object of the present invention is to provide a kind of digital string speech recognition method based on airborne equipment, mainly propose a kind of solution for the problem that the digital string recognition performance is poor in speech recognition, especially considering that the pilot is in the narrow cockpit space The factor of inconvenient operation minimizes the time for them to lower their heads to operate digital string input on the touch screen, thereby improving flight safety and reducing the pilot's control load

Embodiment Construction

[0014] The invention improves the performance of digit string speech recognition from two aspects. 1. Use the framework of two-pass recognition to make a second confirmation of the voice with the number string, and use a digital-specific model for recognition during the second confirmation process, thereby improving the recognition accuracy of the number string. 2. Use partial voice re-input to modify the wrongly recognized number strings, increase the probability of all input content being correctly recognized by reducing the recognition content, and reduce the operation time for correcting wrong recognition. The above solution will be described in detail below with a specific example.

[0015] Assuming that the pilot wants to set the longitude of the navigation destination through voice input, he needs to say the following: "Set the longitude of the destination, east longitude 135 degrees 36 minutes and 48 seconds." (For comparison, we split the above content into two The v...

Abstract

The invention discloses a numerical string voice identification method based on the airborne equipment. According to the method, a two-times-identification framework is employed at an identification stage to carry out secondary confirmation for the voice with a numerical string, in a secondary confirmation process, a numerical special-purpose model is utilized for identification, and the numerical string identification accuracy rate is improved, at an a result confirmation stage, a local voice re-input mode is employed to modify a wrongly-identified numerical string, the possibility that the input content is completely identified accurately is improved through reducing the identification content, and the operation time for modifying identification errors is reduced. Through a man-machine interaction flow of improving the numerical string identification performance and ameliorating the error identification result, the time that a pilot keeps one's head low to input a numerical string on a touch screen can be shortened as much as possible, so flight safety guarantee is improved, and thereby the control load of the pilot is reduced.

Description

technical field [0001] The invention belongs to the field of voice recognition, and in particular relates to a voice recognition method for digital strings based on airborne equipment, which is mainly used for quickly inputting digital strings on the airborne equipment and quickly modifying wrongly recognized numbers. Background technique [0002] The cockpit space of the aircraft is small and the control is complicated. The use of voice recognition can improve the ergonomics of the pilot's control of the aircraft and reduce the pilot's operating load. Speech recognition is a technology that recognizes the audio digital signal of human speech as the text information of the speech content. Using this technology, manual input can be replaced by voice input in some occasions where information needs to be input to the machine, providing humans with a A new way of human-computer interaction. [0003] Speech recognition belongs to the category of pattern recognition, and its func...
