摘要： Provided are a method and device for detecting transcription error in a speech recognition corpus. The method of detecting a transcription error in speech recognition corpus includes following steps: (a) receiving the speech recognition corpus including a speech file and a text label for the speech file; (b) performing speech recognition on the speech file of the speech recognition corpus using a speech recognition model and converting the speech recognition result into text; (c) extracting a performance evaluation index of the speech recognition model; (d) extracting a PPL(s2) for the text label and a PPL(s1) for the text using a language model; and (e) detecting a transcription error in text label of the speech recognition corpus using the extracted performance evaluation index and the PPL(s2) and PPL(s1).
