Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It is to be understood that the terminology used herein is for the purpose of describing particular example embodiments only, and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "including," and "having" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order described or illustrated, unless specifically identified as an order of performance. It should also be understood that additional or alternative steps may be used.

Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as "first," "second," and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

For convenience of description, spatially relative terms, such as "inner", "outer", "lower", "below", "upper", "above", and the like, may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features. Thus, the example term "below … …" can include both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1 to 10, according to an embodiment of the present invention, a voice processing apparatus 100 is provided, the voice processing apparatus 100 includes a panel 10, a rear casing 20, a sound pickup module 30, and a sound insulation assembly, at least two sound holes 11 are opened on the panel 10, the at least two sound holes 11 are spaced apart from each other along a propagation direction of a voice command, the panel 10 is fitted with the rear casing 20, and a mounting space is formed between the panel 10 and the rear casing 20, the sound pickup module 30 is disposed in the mounting space, the sound pickup module 30 includes a main board 31 and microphones 32 having the same number as the sound holes 11, the microphones 32 are disposed on the main board 31, sound pickup ports of the microphones 32 are disposed corresponding to the sound holes 11, the sound insulation assembly is provided with a sound insulation structure, the sound insulation assembly is disposed at least outside the sound pickup module 30, and the sound holes 11 are communicated with the sound pickup ports through the sound insulation structure.

Specifically, when the speech processing device 100 is used for the vehicle 1000 and the vehicle 1000 needs to be controlled, the user issues a speech control command, and since at least two sound holes 11 (one microphone 32 is correspondingly arranged for each sound hole 11) are arranged at intervals along the propagation direction of the speech command, the speech command is determined through the time difference of capturing the speech command by each microphone 32, and other interference noise is discarded to ensure the accuracy of speech input, thereby ensuring the effectiveness of controlling the vehicle 1000.

It is to be understood that in the present invention, the arrangement of at least two microphones 32 forms an end-fire microphone 32 array, and this configuration is referred to as a differencing array when the front microphone 32 in the array (the first microphone 32 to which sound propagating on the axis arrives) is summed with the inverted and delayed signal from the rear microphone 32. This can be used to create cardioid, hypercardioid or hypercardioid pick-up modes in which sound behind the array is greatly attenuated.

When the distance and time delay between microphones 32 are chosen correctly, the beam forming for aliasing frequency response delay superposition with small frequencies is a cardioid, or hypercardioid, pattern. The front-end array of cardioid modes has no signal attenuation and, in theory, at the 180 ° position, the incident sound pressure can be completely neglected. For example, a first order (two microphones 32) delay and a signal attenuation of 6db across the beamformer.

In addition, the sounds received by different microphones 32 in the endfire array differ only in arrival time, and the differential array beamformer does not have a flat frequency response, but rather a high pass filter response characteristic up to zero frequency. The response of the first order beamformer (two microphone elements) increases with increasing frequency, tending to flatten out at the aliasing frequency.

It should be noted that, in the embodiment of the present invention, the microphones 32 are arranged along the same straight line, as shown in fig. 1, P in fig. 1 indicates a propagation direction of the voice command, and the voice command may propagate from left to right or from right to left, an installation indication mark is arranged on the voice processing apparatus 100, and installation is performed according to the direction of the installation indication mark, so as to ensure that after the installation of the voice processing apparatus 100 is completed, there is a single direction when capturing the voice command, so as to ensure the accuracy of voice input, and thus ensure the effectiveness of controlling the vehicle 1000.
