Problems solved by technology

[0003] However, the existing voice recognition technology often can only realize the recognition of the voice directly sent by people, such as: voice control to open the door, but when the user has a courier delivered to the door, since the user is not at home, the door cannot be remotely controlled to open, and then the courier It is impossible to sign for the courier, and it is necessary to discuss with the courier to re-sign for the courier, which not only wastes the time of the courier, but also brings great changes to the user;

Embodiment 1

[0120] Use the position location unit to locate the current location of the user, use the user location analysis unit to establish a plane two-dimensional model of the area where the user is located, and use the user's address as the center of the circle to establish a plane Cartesian coordinate system, the user currently located by the location location unit The coordinates of the location are (12, 6), and the distance L between the user's current location and his address is calculated according to the following formula i Calculation:

[0121] ;

[0122] L i =13.416≥L=1, indicating that the user is far away from the address and can only open the door through remote voice recognition, and use the recognition circuit conversion unit to convert the first voice recognition circuit to recognize the user's remote voice signal;

[0123] Among them, L=1km represents the set distance threshold.

Embodiment 2

[0125] Use the position location unit to locate the current location of the user, use the user location analysis unit to establish a plane two-dimensional model of the area where the user is located, and use the user's address as the center of the circle to establish a plane Cartesian coordinate system, the user currently located by the location location unit The coordinates of the location are (0.5, 0.25), and the distance L between the user's current location and his address is calculated according to the following formula i Calculation:

[0126] ;

[0127] L i When =0.559

[0128] Among them, L=1km represents the set distance threshold.

[0129] Use the position positioning unit to continuously refresh the user's position to form a set of user position coordinates Q={(0.45, 0.22), (0.41, 0.2), (0.35, 0.1...

Abstract

The invention discloses an STM32-based intelligent speech recognition system and method, and belongs to the technical field of speech recognition. The intelligent speech recognition system comprises auser side, a communication module, a speech recognition module and a control side; the user terminal establishes remote communication with the control terminal through the communication module, the user terminal inputs and converts voice signals of a user and transmits the voice signals to the control terminal through the communication module, and the voice recognition module recognizes remote voice signals received by the control terminal. The voice recognition module sends a remote voice recognition result to the control end; the control end controls the relay to be turned on or turned offaccording to the recognition result, and through the remote voice recognition function, when a user is not at home, the door can be remotely controlled to be opened; so that a courier can directly place an express at a doorway after a user remotely controls the door to be opened through voice, the time of the courier is saved; meanwhile, sound wave frequency recognition is additionally arranged, so remote voice recognition is safer.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to an STM32-based intelligent voice recognition system and method. Background technique [0002] Speech recognition refers to the voice communication with the machine. The machine recognizes the content of people's speech and performs corresponding operations according to the content of the speech. In the past two decades, speech recognition technology has made remarkable progress, and it has begun to move from the laboratory to the market. The development of speech recognition technology has changed people's way of life and made people's life more convenient; [0003] However, the existing speech recognition technology often can only realize the recognition of the speech directly sent by people, such as: voice control to open the door, but when the user has a courier delivered to the door, since the user is not at home, the door cannot be opened by remote control, and the...
