Specifically, a full-house distributed voice gateway system with 2 rooms and 3 voice panels installed in each room is taken as an example, and a frame diagram thereof is shown in fig. 1.
The voice control is as follows:
if the user sends voice in the room 1 and the voice content is a wake-up word, the wake-up word is collected by the voice recognition modules of the slave voice panel 1, the slave voice panel 2 and the master voice panel 1, and the voice panel 1 and the slave voice panel 2 send the wake-up word to the master voice panel 1, so that the master voice panel 1 judges the position of the user according to the voice intensity of the received wake-up word, the position and the positioning angle of the slave voice panel 1 and the position and the positioning angle of the slave voice panel 2, calculates the quotient of the voice intensity collected from the voice panel 1 and the distance between the slave voice panel 1 and the position of the user, and the quotient of the voice intensity collected from the voice panel 2 and the distance between the slave voice panel 2 and the position of the user, wakes up the slave voice panel corresponding to the largest of the two quotients, and performs voice interaction with the user.
If a user sends a voice to turn on the air conditioner in the room 1, the voice recognition modules of the slave voice panel 1, the slave voice panel 2 and the master voice panel 1 collect the voice to turn on the air conditioner, the slave voice panel 1 and the slave voice panel 2 send the voice to the master voice panel 1, and the master voice panel 1 judges the position of the user according to the received voice intensity of turning on the air conditioner, the position and the positioning angle of the slave voice panel 1 and the position and the positioning angle of the slave voice panel 2 because the air conditioner is turned on and is a control command without specific equipment, wherein the positioning basis is as follows: the intersection point of the extension lines of the positioning angles of the two voice panels is the position of the voice sender, and as a result, the user is in the room 1, and then the control is executed according to the voice to turn on the air conditioner in the room 1. In addition, the quotient of the voice intensity collected from the voice panel 1 and the distance between the voice panel 1 and the user position and the quotient of the voice intensity collected from the voice panel 2 and the distance between the voice panel 2 and the user position can be calculated, the largest quotient is awakened from the voice panel, and the voice interaction is performed with the user, such as replying "receiving", so that the user experience is improved.
Specifically, the voice recognition modules of the slave voice panel 21, the slave voice panel 22 and the main voice panel 2 may receive the voice "turn on the air conditioner", but the result calculated by the main voice panel 2 is that the user is not in the room 2, and thus, the voice recognition module is not executed.
If a user sends a voice to turn on the air conditioner in the room 2 in the room 1, the voice recognition modules of the slave voice panel 1, the slave voice panel 2 and the master voice panel 1 all collect the voice to turn on the air conditioner in the room 2, the slave voice panel 1 and the slave voice panel 2 send the 'turn on the air conditioner in the room 2' to the master voice panel 1, because the 'turn on the air conditioner in the room 2' contains specific equipment, the master voice panel 1 sends the 'turn on the air conditioner in the room 2' to the master voice panel 2, and the master voice panel 2 receives the 'turn on the air conditioner in the room 2' and performs the turn on of the air conditioner. In addition, the main voice panel 1 judges the position of the user according to the received voice intensity of 'opening the air conditioner of the room 2', the position and the positioning angle of the auxiliary voice panel 1 and the position and the positioning angle of the auxiliary voice panel 2, calculates the quotient of the voice intensity collected from the voice panel 1 and the distance between the voice panel 1 and the position of the user and the quotient of the voice intensity collected from the voice panel 2 and the distance between the voice panel 2 and the position of the user, awakens the auxiliary voice panel corresponding to the largest of the two quotients, and performs voice interaction with the user.
In addition, the voice recognition modules of the slave voice panel 21, the slave voice panel 22 and the master voice panel 2 may also receive the voice "turn on the air conditioner of the room 2", and the master voice panel 2 performs the turning on of the air conditioner since the room 2 is the room where the master voice panel 2 is located.
Specifically, for repeated voices, it is possible to determine whether to perform voice control according to the operation state of the device, such as if the air conditioner of room 2 is turned on but the "turn on room 2 air conditioner" transmitted from the main voice panel of room 1 is received, and not performed, or if the "turn on air conditioner" transmitted from the voice panel 21 and the "turn on air conditioner" transmitted from the voice panel 22 in room 2 is received, and not performed.
