Sound control program selection method and system for intelligent television

Abstract

The invention relates to a sound control program selection method for an intelligent television, and the method comprises the steps: S10, enabling an intelligent television terminal voice command extraction module to obtain a specific voice start instruction, starting to reduce the volume of a first loudspeaker which plays a program currently or adjusting the volume to be zero, enabling an intelligent television terminal to detect whether there is a specific voice instruction in a preset time period or not: switching to step S20 if there is the specific voice instruction in the preset time period, or else adjusting the volume of the loudspeaker which plays the current program to an original value; S20, enabling the intelligent television terminal to obtain the specific voice command, converting the original voice signal into a voice pulse sequence, extracting a voice feature vector through voice recognition, and judging the specific class of the instruction, wherein the class comprisesthe direct execution of an operation instruction and the inquiry execution of the operation instruction through the second loudspeaker; S30, outputting a corresponding control signal according to a voice recognition result, and carrying out the explanation and querying of the current state for an operator. The method is used in the intelligent television terminal, starts a sound control command through the specific voice start instruction, and is convenient and flexible in voice operation.

Description

technical field [0001] The invention relates to the field of channel selection of smart TVs, in particular to a voice-activated broadcast selection method for smart TVs and a corresponding voice-controlled broadcast selection system. Background technique [0002] Current smart TVs use a remote controller to select channels on the same TV display screen. Channel selection can be switched on the display screen, or a reduced picture-in-picture selection can be performed, or other methods occupying the main display screen can be realized. In the prior art, the channel selection methods of smart TVs on the TV display screen are all displayed on the main screen, which affects the normal viewing of programs by users. [0003] In view of the above technical problems, intelligent channel selection is realized by improving the remote control or controlling by mobile devices, such as the channel selection system for smart TV disclosed in patent CN201310729636.5, which intercepts progra...

Problems solved by technology

Although this method realizes convenient voice-controlled operation, it needs to “dialogue” with the remote controller to issue commands at close range, and cannot control channel selection anytime and anywhere, and its voice control function is limited, and the input information is rigid, requiring the operator to be familiar with its function allocation and The corresponding relationship of each field can accurately realize the operation
