Embodiment 1
[0035] Such as figure 1 As shown, the present invention provides a test environment control system for speech recognition, including:
[0036] A playback device 10 includes: a player, which has a volume adjustment terminal, and the player can play a test voice with a current volume value. The volume adjustment terminal can receive a volume-up driving message and a volume-down driving message. The player can drive the player to play the corresponding volume according to the volume-up driving information or the volume-down driving information.
[0037] A control unit has an input terminal and a control information output terminal, and the control information output terminal is connected with the volume adjustment terminal of the player. The control information output terminal is capable of outputting volume up driving information and volume down driving information. The input terminal can acquire the target decibel value, the first threshold and the second threshold input by ...
Embodiment 2
[0055] Such as figure 2 As shown, this embodiment provides a test environment control system for speech recognition on the basis of Embodiment 1, including:
[0056] The control unit of the playback device 10 receives a set time length, the control unit obtains multiple decibel values collected by the decibel sensor 20 in real time, and calculates the decibel average value of the multiple decibel values collected by the single time length. Get the difference between the decibel average and the target decibel value.
[0057] The decibel sensor 20 collects the decibel value of the test position in real time. For example, if the set time length is 3s, all the decibel values collected by the decibel sensor for the first time length of 3s are first stored. The six sampling values are 37dB, 42dB, 41dB, 38dB, 44dB, 39dB, calculate the average decibel value of the six decibel values collected in the first time length of 3s is 40dB, and the difference between the obtained a...
Embodiment 3
[0071] This embodiment provides a test environment control method for speech recognition, including:
[0072] Configure a playback device, which includes:
[0073] A player has a volume adjustment terminal, and the player can play a test voice with a current volume value. The volume adjustment terminal can receive a volume-up driving message and a volume-down driving message. The player can drive the player to play the corresponding volume according to the volume-up driving information or the volume-down driving information.
[0074] A control unit has an input terminal and a control information output terminal, and the control information output terminal is connected with the volume adjustment terminal of the player. The control information output terminal is capable of outputting volume up driving information and volume down driving information. The input terminal can acquire the target decibel value, the first threshold and the second threshold input by the user. The fi...
