Abstract

The present application discloses a speech processing circuit, comprising: an input module and a data conversion module, the output end of the input module is connected to the input end of the data conversion module; the input module is used to obtain a speech input signal, and input the speech The signal is converted into a digital signal in the form of pulse density modulation (PDM); the data conversion module is used to convert the digital signal in the form of PDM into a digital signal in the form of pulse code modulation (PCM) and output it, wherein the digital signal in the form of PDM and the form of PCM The digital signals have the same sampling rate. The application can reduce the delay when the voice processing circuit processes the voice signal, and improve the response speed of the voice processing.

Description

technical field [0001] The application belongs to the field of audio technology, and in particular relates to a voice processing circuit and electronic equipment. Background technique [0002] Generally, the voice processing circuit can collect voice signals from the outside, and convert the voice signals into digital signals in the form of pulse density modulation (PDM). In order to perform voice activity detection and keyword detection, etc., it is necessary to convert the digital signal in the form of PDM into a digital signal in the form of pulse code modulation PCM. However, in the related art, there is a certain delay in the processing of the voice signal by the voice processing circuit, resulting in a slow response speed of the voice processing. Contents of the invention [0003] Embodiments of the present application provide a voice processing circuit and electronic equipment, which can reduce the delay when the voice processing circuit processes voice signals, an...
