Abstract

A voice control circuit and a smart television, the voice control circuit comprises a smart television SOC chip, a digital audio signal processor, a first interface module, a second interface module and a recovery module, the first interface module is connected with the digital audio signal processor and the smart television SOC chip, and is used for an internal voice interface of the smart television; the second interface module is connected with the digital audio signal processor and the smart television SOC chip and is used for an external voice interface of the smart television, and the recovery module is used for sending a sound signal output by a smart television power amplifier to the first interface module and the second interface module as an echo cancellation reference signal. The recovery function is started when the second interface module is connected to the intelligent voice device, or the recovery function is closed when the second interface module is connected to the non-intelligent voice device, so that the problems that the voice input path is single and the standby power consumption exceeds the standard in the scheme that a traditional intelligent television SOC chip is matched with an external DSP to achieve intelligent voice control are solved.

Description

technical field [0001] The application belongs to the field of smart TVs, and in particular relates to voice control circuits and smart TVs. Background technique [0002] With the development of intelligent voice technology, more and more smart devices begin to support intelligent voice control. As a necessary smart product for the family, smart TV has an indispensable function of intelligent voice control. Existing smart TVs support intelligent voice in different ways, and the prior art provides the following implementation schemes: using a smart TV system-on-chip (SOC) with a third-party software development kit (Software Development Kit, SDK) ) algorithm to achieve intelligent voice control, directly using the SOC to run the algorithm has high requirements on the performance of the SOC, and the performance of some low-end SOCs cannot be satisfied, especially when the SOC runs software to decode audio and video, its central processing unit (Central Processing Unit, CPU) A...
