Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] The speech recognition device provided in the embodiment of the present invention is mainly aimed at a speech interaction device with a far-field recognition function, for example, a smart picture frame, a smart home, and the like. Of course, it can also be applied to other speech recognition scenarios as required, and there is no limitation here.
[0046] Such as figure 1 As shown, it is a schematic structural diagram of a speech recognition device pr...

The invention relates to a speech recognition device and method, which are used to solve the problem that the speech recognition effect cannot be improved when many people speak in a noisy environment in the current speech recognition process. The device includes: a speech recognition module, which collects audio information and performs speech recognition; an environment judgment module, when the semantic content recognized by the speech recognition module cannot match the content in the semantic database, judges whether the audio information includes audio information of noisy environment and the user Audio information; the main control module, when the audio information includes noisy environment audio information and user audio information, determine the conditions for collecting audio information according to the input volume and voltage amplitude of the audio information, and then optimize the audio information collected next time, And when the speech recognition module collects audio information and starts the next speech recognition process, the effect of speech recognition is improved.
Description
technical field [0001] The invention relates to the technical field of speech recognition, in particular to a speech recognition device and method. Background technique [0002] Speech recognition technology refers to the technology by which a machine converts audio input into text or commands. In the speech recognition process, especially when the microphone array has a far-field recognition function, the sensitivity of audio signal acquisition will be relatively high. If there are other irrelevant people talking around the user, the microphone will collect the voices of multiple people at the same time, and the sound amplitude of the irrelevant part will be higher than the voice recognition threshold, resulting in the interaction between the user and the device and the interaction between other people around. Chatting is collected by the device, making it difficult for the speech recognition module to judge the user's intention and make a correct response. [0003] Tradi...
