Abstract

According to one embodiment, an electronic device determines whether one or more devices should be controlled based on a second utterance input subsequent to a first utterance input from outside in accordance with the first utterance. The electronic device includes a management unit and a controller. The management unit prepares and manages a determination audio data item for determining whether the first utterance is a desired utterance by utterances input from outside at a plurality of times, and determines whether the first utterance is the desired utterance using the prepared and managed determination audio data item. The controller controls the one or more devices based on the second utterance.

Claims

1. A control method for determining whether one or more devices should be controlled based on a second utterance input subsequent to a first utterance input from outside in accordance with the first utterance, the method comprising:

determining whether the first utterance is a desired utterance using a prepared and managed determination audio data item by a management unit; and

in response to the management unit determines that the first utterance is the desired utterance, controlling the one or more devices based on the second utterance by a controller

receiving a third utterance;

in response to the third utterance being received after the second utterance within a time threshold, parsing the third utterance as a control content configured to control one or more devices;

in response to the third utterance being received after the second utterance exceed a time threshold, determining whether the third utterance is a desired utterance.

2. The control method according to claim 1, wherein the process of determining whether the first utterance is the desired utterance comprising:

receiving the first utterance;

reading recognition data;

comparing the recognition data with the first utterance; and

in response to the first utterance being recognized as a reserved expression, determining a recognition probability;

in response to the recognition probability being less than a first threshold, prompting for more utterance input.

3. A control method for determining whether one or more devices should be controlled based on a second utterance input subsequent to a first utterance input from outside in accordance with the first utterance, the method comprising:

determining whether the first utterance is a desired utterance using a prepared and managed determination audio data item by a management unit; and

in response to the management unit determining that the first utterance is the desired utterance, controlling the one or more devices based on the second utterance by a controller;

before controlling the one or more devices based on the second utterance, the method further comprising;

registering a first additional information corresponding to each of the reserved expressions in accordance with a plurality of reserved expressions; and

changing an operation of a device in accordance with the first additional information;

wherein the in response to the management unit determining that the first utterance is the desired utterance further comprising;

in response to the management unit determining that the first utterance is the desired utterance and the changed operation.

4. The control method according to claim 3, wherein changing an operation of a device in accordance with the first additional information further comprising:

in response to the first additional information is a first preset information, extending a first time threshold.
