The invention provides a construction device and a construction method of a self-learning speech recognition system. The construction device is applied to a speech recognition system; the speech recognition system comprises a microphone and a speech recognition module applying the construction device; the microphone is connected with the speech recognition module; the construction device comprisesan analysis unit which is used for analyzing the output signal of the microphone to obtain a plurality of signal parameters, and an identification unit which is connected with the analysis unit and judges whether the output signal is a preset activation speech or not according to the signal parameters. The construction device and the construction method have the beneficial effects that a power supply module, an ADC and a CPU in the standby process are enabled to sleep by activating the speech to wake up, so that energy consumption in the standby process is reduced.
Description
technical field [0001] The invention relates to the technical field of voice recognition, in particular to a construction device and a construction method of a self-learning speech recognition system. Background technique [0002] With the rapid development of computer application technology, the application of speech or other types of sound recognition technology is becoming more and more extensive, and the demand for sound recognition is also increasing. The current ultra-high-definition smart TVs and smart speakers still need to retain the voice wake-up function during standby, so the voice recognition system still needs to work, that is, the power module, ADC (Analog-to-Digital Converter, analog-to-digital converter), CPU ( Central Processing Unit (central processing unit) are still in the working mode, so that a large amount of energy is consumed in the standby process. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, a dev...
