Electronic device with wakeup word determined multi-mode operation

1. An artificial intelligence device comprising:

a microphone configured to receive a speech input; and

a processor configured to:

recognize a first wakeup word for calling the artificial intelligence device in response to receiving a first speech input;

recognize a second wakeup word for setting an operation mode in response to receiving a second speech input;

operate in an interaction mode based on recognizing the second wakeup word; and

process one or more commands received after the second wakeup word according to the operation mode indicated by the second wakeup word,

wherein the interaction mode is selectable from among a conversation mode, a multiple request mode, a secret mode, an application setting mode, and a specific device call mode,

wherein the conversation mode is a mode in which a command is processed in consideration of a previous conversation, and is a mode for inducing mutual conversation with a user,

wherein the multiple request mode is a mode for collectively receiving a plurality of commands and collectively performing processing on the plurality of commands,

wherein the secret mode is a mode for deleting a conversation record on the artificial intelligence device,

wherein the application setting mode is a mode in which a speech recognition agent can be set based on a speech input, and

wherein the specific device call mode is a mode for enabling only home appliances designated by the user.

2. The artificial intelligence device according to claim 1 , wherein the processor is further configured to operate in the interaction mode based on the second wakeup word being continuously recognized after the first wakeup word is recognized.

3. The artificial intelligence device according to claim 1 , wherein the processor is further configured to:

operate in a normal mode to process a first command based on the first command being received after the first wakeup word is recognized; and

process a second command based on the first wakeup word being recognized after the first command is processed and the second command is received after the first wakeup word is recognized.

4. The artificial intelligence device according to claim 3 , wherein, in the conversation mode, based on a fourth command being received within a speech waiting period after a third command is processed, the processor is further configured to process the fourth command without input of the first wakeup word,

wherein the speech waiting period in the conversation mode is longer than a speech waiting period in the normal mode.

5. The artificial intelligence device according to claim 3 , wherein, based on the second wakeup word corresponding to the multiple request mode being recognized after the first wakeup word is recognized and a fifth command and a sixth command are received after the second wakeup word is recognized, the processor is further configured to output a response corresponding to the fifth command and a response corresponding to the sixth command after the fifth command and the sixth command are received.

6. The artificial intelligence device according to claim 5 , wherein the processor is further configured to distinguish the fifth command from the sixth command by using a first identification command included in the fifth command and a second identification command included in the sixth command.

7. The artificial intelligence device according to claim 6 , wherein, based on the processor further receiving an additional response request including the first identification command, the processor is further configured to output an additional response corresponding to the additional response request and related to the fifth command by using the fifth command.

8. The artificial intelligence device according to claim 5 ,

wherein, based on a seventh command being received in the multiple request mode within a speech waiting period after the fifth command and the sixth command are processed, the processor is further configured to process the seventh command without input of the first wakeup word,

wherein the speech waiting period in the multiple request mode is longer than a speech waiting period in the normal mode.

9. The artificial intelligence device according to claim 1 , wherein, based on an end command being received in the interaction mode or a speech waiting period is ended, the processor is further configured to terminate the interaction mode.

10. The artificial intelligence device according to claim 1 , wherein the second wakeup word corresponding to the specific device call mode includes a plurality of device call words set by the user and respectively corresponding to a plurality of home appliances.

11. The artificial intelligence device according to claim 1 , wherein, based on the second wakeup word corresponding to the secret mode being recognized after the first wakeup word is recognized, the processor is further configured to delete a conversation record of the user.
