    摘要： A closed caption signal processing apparatus comprises a speech recognition unit to recognize speech contents from the speech signal, a speech timing detecting unit to detect a speech timing of the speech contents, a closed caption contents acquisition unit to acquire closed caption contents from the closed caption signal associated with the speech signal, a presentation timing detecting unit to detect a presentation timing of the closed caption contents, an agreement detecting unit to detect an agreement between the speech contents and the closed caption contents, and a time difference calculating unit to calculate a time difference between the speech timing and the presentation timing that are detected on the speech contents and the closed caption contents that agree with each other, respectively.
