Abstract: Disclosed are a speech recognition verification device and a speech recognition verification method, which verify speech recognition results by executing artificial intelligence (AI) algorithms and/or machine learning algorithms in a 5G environment connected for Internet-of-Things. According to an embodiment, the speech recognition verification method includes converting a verification target text item to a verification target spoken utterance by applying a preset utterance condition, analyzing the verification target spoken utterance and outputting a recognition result text item corresponding to an analysis result, and verifying speech recognition performance through comparison between the verification target text item and the recognition result text item. According to the present disclosure, the speech recognition result may be verified objectively by using a spoken utterance generated with random text and various utterance conditions as input of speech recognition.

Abstract: According to an embodiment of the present invention, there is provided a terminal including a memory which stores a prosody correction model; a processor which corrects a first prosody prediction result of a text sentence to a second prosody prediction result based on the prosody correction model and generates a synthetic speech corresponding to the text sentence having a prosody according to the second prosody prediction result; and an audio output unit which outputs the generated synthetic speech.
