The invention discloses a semantic recognition device for tracking a target person. The device includes a microphone array module, a speaker identification module, a storage module, an audio data cache region and a semantic matching module. The microphone array module collects multichannel audio signals from an external sound field and performs voice enhancement processing, and processed audio signals only enhance the audio signals of a sound source of a specific place in the external sound field; the speaker identification module extracts the voiceprint feature collected by the microphone array module and is matched with a voiceprint model of the target person, and whether the specific sound source signal obtained after the enhancement process of the microphone array module comes from thetarget person or not is judged; the semantic matching module recognizes semantic information in audio, and the semantic information is output in a certain form. A voiceprint extraction module and a sound source positioning module, the sound source position of the target person can be positioned in the noisy external sound field, and the voice signal of the target person is converted into semanticinformation of the target person through the audio data cache region and the semantic matching module.
Description
technical field [0001] The invention relates to the field of semantic recognition, in particular to a semantic recognition device for tracking a target person. Background technique [0002] The current general-purpose semantic recognition device is often affected by the interference sound source, and cannot achieve a high recognition success rate in noisy occasions; the recognition target is not optional, and it is not suitable for occasions that need to recognize the semantics of a specific person; When the target sound source moves, it is not easy to achieve a high recognition success rate. [0003] The domestic application publication number is CN105529026A, the patent titled "Speech Recognition Device and Speech Recognition Method". It includes a collector, a first memory, a learner, a second memory, a feature vector extractor, a speech recognizer, and is dedicated to providing the advantages of generating a personal acoustic model based on speaker's speech data and per...
