Abstract: According to an embodiment, an electronic device, in case that a user utterance related to a date and time acquired through the input module is identified as a user utterance for performing a function, based on a date and time when the user utterance is acquired, identifies whether the date and time detected in the user utterance are interpreted as a plurality of dates and times. According to an embodiment, the electronic device, in case that the date and time detected in the user utterance are interpreted as the plurality of dates and times, changes the date detected in the user utterance if a first condition for changing the date is satisfied, and changes the time detected in the user utterance if user's activity record information satisfies a second condition. According to an embodiment, the electronic device recommends performing a function with the changed date or time.

Abstract: Provided is an electronic device that includes a first processor for receiving an audio signal, performing first voice recognition on the audio signal, and transferring a driving signal to a second processor based on a result of the first voice recognition. The second processor performs second voice recognition based on a voice signal by the first voice recognition or the audio signal, in response to the driving signal.

Abstract: Provided is an electronic device and a voice recognition method. The electronic device includes: a memory configured to store at least one instruction, and a processor electrically connected to the memory. The processor is and configured to execute the at least one instruction to: obtain a sound signal corresponding to an utterance, and recognize a voice signal included in the sound signal, based on a determination that a portion of the sound signal corresponds to at least one of a plurality of noise categories, the plurality of noise categories corresponding to a plurality of environments in which a plurality of voice models of voice signals are generated.

Abstract: A frequency multiplier includes a capacitor circuit having a plurality of capacitors therein, and is responsive to a differential input signal applied to an inverting input node and a non-inverting input node thereof. A frequency multiplication circuit (FMC) is provided, which has a plurality of transistors therein. The FMC is configured to receive components of the differential input signal passing through the plurality of capacitors, and multiply a frequency of the components of the differential input signal. A plurality of inductor loads are provided, which are connected to an inverting output node and a non-inverting output node of the FMC, and are configured to convert a current signal generated by the FMC into a voltage signal.
