Embodiment 1

[0044] Embodiment 1 of the present invention provides a voice wake-up method, the step flow of the method can be as follows figure 1 shown, including:

[0045] Step 101, receiving a voice signal.

[0046] In this step, a voice signal used by the user to wake up the intelligent voice interaction device may be received.

[0047] Step 102, compare.

[0048] In this step, the received voice signal may be compared with the pre-stored voice signal including keywords.

[0049] That is, in this embodiment, the user is required to input a voice signal including keywords in advance, for example, small cells.

[0050] Comparing the received speech signal with the pre-saved speech signal including keywords, it can be understood that the speech feature is extracted from the received speech signal, and the speech feature can be but not limited to spectrum or cepstral coefficient The pre-saved speech feature models corresponding to speech signals including keywords are compared to obtain...

Embodiment 2

[0062] Embodiment 2 of the present invention provides a voice wake-up method, and the step flow of the method can be as follows figure 2 shown, including:

[0063] Step 201, receiving a voice signal.

[0064] In this step, a voice signal used by the user to wake up the intelligent voice interaction device may be received.

[0065] Step 202, performing comparison.

[0066] The voice signal received for the first time in the wake-up process of this round may be referred to as voice segment 1 . Comparing the speech segment 1 with the pre-saved speech signal including keywords, the obtained similarity rate can be represented by ρ1.

[0067] Step 203, wake up.

[0068] If ρ1>=α, at this time, it can be considered that the environmental noise is small or the wake-up sound source is close, and the smart voice interactive device can be directly triggered to enter the wake-up state. The smart voice interactive device wakes up successfully, and this process ends, ending the current...

Embodiment 3

[0089] Embodiment 3 of the present invention provides a voice wake-up device, the structure of which can be as follows image 3 shown, including:

[0090] Receiving module 11 is used for receiving speech signal;

[0091] Comparison module 12 is used for comparing the speech signal received by the receiving module with the pre-saved speech signal including keywords;

[0092]The wake-up module 13 is used for if the similarity rate obtained by the comparison module comparison is lower than the first threshold value set, but not lower than the second threshold value set, and the number of times of comparison does not reach the set number of times, then prompting needs Continue to wake up, and trigger the receiving module to receive voice signals again until the number of comparisons reaches the set number of times, triggering the intelligent voice interaction device to enter the wake-up state.

[0093] The wake-up module 13 is also configured to trigger the intelligent voice int...

Abstract

The invention relates to a voice wake up method and device, a medium and equipment. According to the scheme provided by the embodiment of the invention, multiple times of wakeups can be included in each round of wakeup process. In one round of the wake up process, the received voice signal corresponding to one time of wake up is compared with a pre-stored voice signal comprising a keyword to obtain a similarity rate; if the similarity rate is lower than a set first threshold and is not lower than a set second threshold value, and the comparison frequency does not reach the preset frequency, it is prompted that wakeup needs to be continued and then wakeup continues to be carried out once; if the comparison frequency reaches the preset frequency, it is determined that the intelligent voiceinteraction equipment can be waken up, and the intelligent voice interaction equipment is triggered to enter a wakeup state, thereby realizing wakeup of the intelligent voice interaction equipment. Thus, even in the presence of interference, the wake-up confidence can be ensured in a multi-comparison mode, wake-up of the intelligent voice interaction equipment in the presence of interference is completed, and the success rate of voice wake-up is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent voice interaction, in particular to a voice wake-up method, device, medium and equipment. Background technique [0002] At present, intelligent voice interaction devices, such as smart speakers and robots, are more and more widely used. These devices can generally be awakened by the user with a certain keyword. After awakening, the user's direction can be found, and the voice of the user's direction can be enhanced to further recognize the user's voice command. [0003] At present, the wake-up of intelligent voice interactive devices depends on the quality of voice signals including keywords. For pure voice signals, intelligent voice interactive The wake-up success rate of voice interactive devices is low. Contents of the invention [0004] Embodiments of the present invention provide a voice wake-up method, device, medium and equipment, which are used to solve the problem of low success r...
