AI Technical Summary

Problems solved by technology

Nonverbal-related sounds that may often be louder than spoken commands, causing speech recognition devices to misinterpret spoken commands
[0004] Moreover, the existing technology can detect the time when the user opens his mouth as the user's speaking time, but when other non-main users speak, the system often uses the time when the user opens his mouth as the user's speaking time, so there is unnecessary information in the voice information. This increases the amount of communication traffic; in some cases, when a user speaks, the voices of other people other than the user are included in the voice information, and it is not convenient to extract the voice information of the main user

Embodiment 1

[0035] refer to figure 1 Shown, a kind of speech recognition control method, its improvement is: comprise the following steps:

[0036] Step 1: Collecting the user's fingerprint by the fingerprint collector 13;

[0037] Step 2: Extracting speech feature information from the speech database according to the user fingerprint information;

[0038] Step 3: Obtain the environmental voice information of the user's vocalization stage;

[0039] Step 4: Process the ambient voice information based on the user's voice feature information and obtain the user's voice information;

[0040] Step 5: Transmit user voice information.

[0041] In actual situations, armored vehicles carry more than one trainer. When acquiring voice information on the spot, it is often impossible to distinguish whether it is the voice information of the main speaker, resulting in inaccurate extracted voice information. The personnel of the recognition device collects fingerprints, and extracts the user's voice...

Embodiment 2

[0046] refer to image 3 , Figure 4 and Figure 6 As shown, a voice recognition control device is improved in that it includes a voice acquisition device 1, a voice recognition device 2, an information transmission device 3, a host 4 and a power supply device 5; the voice acquisition device 1 includes a The fingerprint collector 13 and the microphone 11 for receiving voice; the voice recognition device 2 includes a voice processing device 21, a voice matching device 22 and a voice conversion device 23, and the voice processing device 21 is connected with the voice acquisition device 1 for use in Receive and process the voice information transmitted by the voice acquisition device 1; the voice matching device 22 is connected with the voice processing device 21, and is used to perform voice matching on the processed voice information and obtain a voice matching result; the voice conversion The device 23 is connected with the voice matching device 22 and the voice processing d...

Embodiment 3

[0049] On the basis of embodiment 2, with reference to Figure 4 As shown, the voice acquisition device 1 further includes a trigger control device 12 for controlling whether to receive voice information, and whether to trigger the subsequent voice recognition device 2 for the received voice information. The setting of the trigger control device 12 can improve the effective audio segment for acquiring voice information.

[0050] Further, the trigger control device 12 has a built-in wake-up device 121 or a trigger button 122 . The wake-up device 121 matches the voice information sent by the user with the wake-up lexicon built in the wake-up device 121. The user needs to send twice consecutive voice information matching the information in the wake-up lexicon, then the voice acquisition device 1 and the voice recognition device 2 is triggered to start, the wake-up lexicon in the wake-up device 121 is a daily communication word used by armored vehicles, and it is a specific sente...

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a speech recognition control device and a speech recognition control method. Background technique [0002] Many vehicles are equipped with devices for voice dialogue, voice braking or voice control. A voice dialog device may perform a function, provide information, or provide a response based on spoken commands. A voice dialogue device may process or convert sound from a microphone into an audio signal or other type of signal. Speech recognition can be applied to audio signals, and the recognized speech can be processed by a semantic interpreter. Based on the interpretation of spoken commands, systems such as dialogue controls can perform actions, generate responses, or perform other functions. The response may be in the form of, for example, an audio signal, a text signal, a command signal, an action by a vehicle system, or other notification to a vehicle operator....
