Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0039] like figure 1 , as shown in 2, the main idea of the present invention is to form a real-time speech enhancement system by integrating the speech enhancement algorithm in a dedicated chip, and by designing the interface and data transmission between the chip and the corresponding microphone. The voice signal is collected by the microphone and directly processed by the voice enhancement algorithm in the chip to obtain an enhanced signal, which is output for secondary use.
[0040] The basic steps of speech enhancement algorithm among the present invention are as follows:
[0041] 1. Use a microphone to receive external signals;
[0042] 2. The signal is sent to the chip, and the analog-to-digital conversion is completed first (if a digital microphone is used, this step can be omitted);
[0043] 3. Perform voice enhancement processing on the ob...
