Problems solved by technology
[0002] In the prior art, household electrical appliances are generally controlled by multiple sets of mechanical switches or remote control boards, which are inhumane to use, and the remote control boards are often not found and unclear. It is inconvenient to operate during the control process and prone to errors. Operating situation
[0003] Voice control technology can partly solve this problem, but the existing voice chip recognition depends on the remote server, and the local voice control circuit must be connected to the server or the cloud through wired or wireless methods. Transmission module, the network signal is susceptible to interference, and the transmission distance is limited

Embodiment Construction
[0012] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0013] The voice recognition control circuit of the present invention includes a voice local control chip and an audio decoding chip, a crystal oscillator and a memory connected to its signal, the audio decoding chip is connected to the speaker signal through a power amplifier chip, and the audio decoding chip is also connected with a microphone.
[0014] like figure 1 In the specific embodiment shown, the audio decoding chip adopts ES8388, the voice local control chip adopts CI1006; the memory adopts Flash memory W25Q64JVSSIG.
[0015] After the user sends a voice command, it is collected by the microphone as an analog signal and input to the audio decoding chip ES8388. The audio decoding chip ES8388 digitizes the analog signal and sends it to the voice local recognition chip for recognition and comparison. After local recognition, ...

A voice recognizing control circuit comprises a voice local control chip, and an audio decoding chip, a crystal oscillator and a memorizer which are in signal connection with the voice local control chip. The audio decoding chip is in signal connection with a horn through a power amplification chip. The audio decoding chip is connected with a microphone. By means of the voice recognizing control circuit, human voice commands can be understood, an executing instruction is output to an operation unit, and the friendly voice interaction is realized; local recognizing and learning are realized through the voice local control chip, no network module is needed, and the use mode is simplified.
Description
technical field [0001] The invention belongs to the field of electronic circuits and relates to an artificial intelligence circuit, in particular to a speech recognition control circuit. Background technique [0002] In the prior art, household electrical appliances are generally controlled by multiple sets of mechanical switches or remote control panels, which are not user-friendly in use, and the remote control panels are often not found and cannot be clearly distinguished. It is inconvenient to operate during the control process and prone to errors. operating conditions. [0003] Voice control technology can partially solve this problem, but the existing voice chip recognition relies on a remote server, and the local voice control circuit must be wired or wirelessly connected to the server or the cloud. To achieve voice recognition, it is generally necessary to configure the network Transmission module, the network signal is susceptible to interference, and the transmiss...
