Abstract: Provided is a system and method for recognizing a user's speech. A method, performed by a server, of providing a text string for a speech signal input to a device includes: receiving, from the device, an encoder output value derived from an encoder of an end-to-end automatic speech recognition (ASR) model included in the device; identifying a domain corresponding to the received encoder output value; selecting a decoder corresponding to the identified domain from among a plurality of decoders of an end-to-end ASR model included in the server; obtaining a text string from the received encoder output value using the selected decoder; and providing the obtained text string to the device.

Abstract: The clock generator is provided and includes a phase detector, a voltage generator, a voltage-to-current converter, and an oscillation circuit. The voltage generator generates a control voltage. The voltage-to-current converter converts the control voltage into an internal current having a level based on a resistance value of a resistor circuit, the resistance value set based on first control information. The oscillation circuit generates a output clock having a frequency based on the level of the internal current and a capacitance value of a capacitor circuit, the capacitance value set based on second control information. The clock generator maintains a frequency value and varies jitter characteristics of the output clock in response to the first control information and the second control information.
