Electronic device and method for controlling electronic device
An electronic device including a speaker; a microphone; a memory configured to store a voice recognition model; and a processor configured to: identify, while a first sound signal is input through the microphone, whether a wake-up word is included in a second sound signal that is output through the speaker by inputting the second sound signal into a wake-up word detection model, and identify, based on identifying that the wake-up word is not included in the second sound signal, whether the wake-up word is included in the first sound signal by inputting the first sound signal into the wake-up word detection model.
1. An electronic device comprising:
a speaker;
a microphone;
a memory; and
a processor configured to:
based on a wake-up word not being included in a second sound signal that is output through the speaker and being included in a first sound signal while the first sound signal is input through the microphone, activate a voice recognition function corresponding to a voice recognition model; and
based on the wake-up word being included in the second sound signal and not being included in the first sound signal, control the voice recognition function corresponding to the voice recognition model not to be activated.
2. The electronic device as claimed in claim 1 , wherein the processor is further configured to identify whether a first wake-up word among a plurality of wake-up words corresponding to each of a plurality of voice recognition models is included in the second sound signal by inputting the second sound signal into a wake-up word detection model corresponding to each of the plurality of voice recognition models, based on the plurality of voice recognition models stored in the memory.
3. The electronic device as claimed in claim 2 , wherein the processor is further configured to, based on identifying that the first wake-up word is not included in the second sound signal, identify whether the first wake-up word is included in the first sound signal by inputting the first sound signal into the wake-up word detection model corresponding to each of the plurality of voice recognition models.
4. An electronic device comprising:
a speaker;
a microphone;
a memory configured to store a plurality of wake-up word detection models and a plurality of voice recognition models, wherein each respective wake-up word detection model of the plurality of wake-up word detection models, and each respective voice recognition model of the plurality of voice recognition models, corresponds to a respective wake-up word of a plurality of wake-up words; and
a processor,
wherein the processor is configured to:
identify whether a first wake-up word included within the plurality of wake-up words is included in a first sound signal that is input through the microphone by inputting the first sound signal into each respective wake-up word detection model of the plurality of wake-up word detection models, and
identify, based on identifying that the first wake-up word is included in the first sound signal, whether the first wake-up word is included in a second sound signal output through the speaker by inputting the second sound signal into the respective wake-up word detection model of the plurality of wake-up word detection models corresponding to the first wake-up word.
5. The electronic device as claimed in claim 4 , wherein the processor is further configured to, based on identifying that the first wake-up word is included in the second sound signal through the wake-up word detection model corresponding to one of the wake-up words, control the plurality of voice recognition models so as not to be activated.
6. The electronic device as claimed in claim 5 , wherein the processor is configured to, based on identifying that the first wake-up word is not included in the first sound signal, control the plurality of voice recognition models so as not to be activated.
7. A method for controlling an electronic device including a memory that stores a voice recognition model, the method comprising:
based on a wake-up word not being included in a second sound signal that is output through a speaker and being included in a first sound signal while the first sound signal is input through a microphone, activating a voice recognition function corresponding to the voice recognition model; and
based on the wake-up word being included in the second sound signal and not being included in the first sound signal, controlling the voice recognition function corresponding to the voice recognition model not to be activated.
8. The method as claimed in claim 7 , wherein the identifying of whether the wake-up word is included in the second sound signal comprises identifying whether a first wake-up word among a plurality of wake-up words corresponding to each of a plurality of voice recognition models is included in the second sound signal by inputting the second sound signal into a wake-up word detection model corresponding to each of the plurality of voice recognition models, based on the plurality of voice recognition models being stored in the memory.
9. The method as claimed in claim 8 , wherein the identifying of whether the first wake-up word among the plurality of wake-up words corresponding to each of the plurality of voice recognition models is included in the second sound signal comprises identifying whether the first wake-up word is included in the first sound signal by inputting the first sound signal into the wake-up word detection model corresponding to each of the plurality of voice recognition models based on identifying that the first wake-up word is not included in the second sound signal.
10. A method for controlling an electronic device including a memory that stores a plurality of voice recognition models and a plurality of wake-up word detection models, the method comprising:
identifying whether a first wake-up word among a plurality of wake-up words is included in a first sound signal that is input through a microphone by inputting the first sound signal into each respective wake-up word detection model of the plurality of wake-up word detection models; and
identifying, based on identifying that the first wake-up word is included in the first sound signal, whether the first wake-up word is included in a second sound signal that is output through a speaker by inputting the second sound signal into a respective wake-up word detection model of the plurality of wake-up word detection models corresponding to the first wake-up word.
11. The method as claimed in claim 10 , further comprising controlling the plurality of voice recognition models so as not to be activated based on identifying that the first wake-up word is included in the second sound signal through the wake-up word detection model corresponding to the first wake-up word.
12. The method as claimed in claim 10 , further comprising controlling the plurality of voice recognition models so as not to be activated based on identifying that the first wake-up word is not included in the first sound signal.
