Abstract: A speech synthesizer includes a memory configured to store a plurality of sentences and prior information of a word classified into a minor class among a plurality of classes with respect to each sentence, and a processor configured to determine an oversampling rate of the word based on the prior information, determine the number of times of oversampling of the word using the determined oversampling rate and generate sentences including the word by the determined number of times of oversampling. The plurality of classes includes a first class corresponding to first reading break, a second class corresponding to second reading break greater than the first break and a third class corresponding to third reading break greater than the second break, and the minor class has a smallest count among the first to third classes in one sentence.

Abstract: Disclosed are a method and an apparatus for speech recognition. In a method for processing speech recognition according to an embodiment of the disclosure, a relationship of a named entity is extracted and each named entity is clustered based on the extracted relationship of the named entity. An utterance intent is grasped by considering not only information about the named entity itself, but also relationship information of the clustered named entity tagged in the named entity, which may result in improvement of accuracy of speech recognition in the apparatus for speech recognition. A user equipment of the present disclosure can be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.
