When the method in the above embodiment is actually applied, any existing speech enhancement algorithm can be used as a speech enhancement algorithm used by the speech recognition device during operation as data support, and the existing speech enhancement algorithm is selected as an example as follows:
auditory masking method
The auditory masking effect means psychologically that when a strong signal is present in the vicinity of a weaker signal, the weak signal will not be perceived, i.e. the perception threshold of sound X is increased by the presence of sound B, a phenomenon known as the auditory masking effect of the human ear. For example, in a factory building with a noisy machine sound, the workers need to increase the voice to make the other party hear the voice. In the auditory masking effect, the maximum sound pressure level of the masked imperceptible signal is called the masking threshold, below which all signals will be masked. Due to the presence of the masking sound, signals in the vicinity of which only below the masking threshold, even if their energy is not zero, cannot be perceived because of the masking effect. Currently, there are three main types of speech enhancement methods based on auditory masking: the method based on the probability of the noise being masked: when the noise component is masked by the voice, the voice signal with the noise is not processed, and when the noise component is not masked by the voice, the voice is processed by using a voice enhancement algorithm. Auditory masking effects are combined with spectral subtraction: the noise weight coefficient a and the power smoothing coefficient b in the spectral subtraction are dynamically adjusted through the auditory masking threshold, and the balance is achieved between noise reduction and distortion reduction. The perceptual filter method comprises the following steps: the perception filter does not completely eliminate the residual noise, and utilizes the masking effect of human ears to control the residual noise to be below a masking threshold, so that the residual noise is not perceived by the human ears, and the distortion of voice can be reduced while the noise is suppressed.
There are three main categories of current speech enhancement methods based on auditory masking.
1. The method based on the probability of the noise being masked: when the noise component is masked by the voice, the voice signal with the noise is not processed, and when the noise component is not masked by the voice, the voice is processed by using a voice enhancement algorithm.
2. Auditory masking effects are combined with spectral subtraction: the noise weight coefficient a and the power smoothing coefficient beta in the spectral subtraction are dynamically adjusted through the auditory masking threshold, and balance is achieved between noise reduction and distortion reduction.
3. The perceptual filter method comprises the following steps: the perception filter does not completely eliminate the residual noise, and utilizes the masking effect of human ears to control the residual noise to be below a masking threshold, so that the residual noise is not perceived by the human ears, and the distortion of voice can be reduced while the noise is suppressed.
In summary, the deployment areas of the industrial devices can be effectively identified through the above embodiments, so that a local area network is further constructed in the identified deployment areas of the industrial devices, and the subsequent voice recognition devices deployed on the industrial devices have interconnection and data sharing conditions, so that a user can issue a control command of any industrial device at any deployment position of the voice recognition device in the deployment areas of the industrial devices; in the execution process of the steps, by identifying and acquiring the position information of each industrial device, a plurality of groups of voice recognition devices can be further configured in the specified range of the industrial device deployment area, so that the aim of issuing the industrial device control command by a convenient user through the voice recognition devices is fulfilled; meanwhile, the voice recognition equipment deployed on the industrial equipment can be continuously coordinated twice, so that the voice recognition equipment is suitable for the industrial equipment, and the application quantity of the voice recognition equipment is more suitable, so that the aim of saving the cost for configuring the voice recognition equipment for system implementation is fulfilled; in addition, the robust speech enhancement algorithm-based industrial equipment speech control system described in the embodiment can provide necessary step execution conditions for the step execution of the method, so that the speech recognition equipment deployed on the industrial equipment can have a specified speech recognition function, and the industrial equipment is driven to operate by the specified speech recognition function.
