1. A television receiving apparatus, comprising:
a broadcast signal receiving and processing unit configured to process broadcast signals according to broadcast standards;
a communication unit configured to connect with a network and communicate with one or more servers and one or more external devices;
a monitor configured to display an image;
a speaker configured to output voice;
a microphone configured to receive a voice input;
an interface unit configured to receive a command signal from outside or output a signal to an external device;
a control unit in connection with the interface unit, the communication unit, the monitor, the speaker, the broadcast signal receiving and processing unit and configured to:
detect a voice input to the microphone based on voice data input via the interface unit;
in response to a voice period over a first period of time with voice input being detected, determine that a first piece of voice data in the voice period is received;
send a first time point of the voice period as a trigger signal of the first piece of voice data, wherein the first time point of the voice period is a start time point or an end time point of the voice period;
send the first piece of voice data for voice recognition and language processing;
obtain a second time point associated with first command data corresponding to the first piece of voice data, wherein the first command data is a command content generated after the voice recognition and language processing;
generate a first control signal for a target controlled object based on the command data and a delay time associated with a difference between the first time point of the voice period and the second time point associated with the first command data;
send the first control signal to the target controlled object to implement a control operation corresponding to the first piece of voice data.
