INTERROGATIVE SPEECH PORTION EXTRACTION PROCESSING PROGRAM FOR SPEECH DATA, METHOD, AND DEVICE, AND CLIENT INQUIRY TREND ESTIMATION PROCESSING PROGRAM, METHOD, AND DEVICE USING INTERROGATIVE SPEECH PORTION OF SPEECH DATA
An interrogative speech portion extracting device (10) inputs speech dialogue data (3) in which the speeches of an operator and a client are recorded on separate channels, calculates the power value of the speech for each unit section in each of the channels, determines a person who speaks at a constant power in a predetermined section for a longer time than anyone else and speaks earlier than anyone else as a preceding leading speaker, and identifies the period in which the preceding leading speaker continuously speaks from the beginning of the speech. If the preceding leading speaker is a client, the interrogative speech portion extracting device (10) identifies the period as an interrogative speech portion and extracts interrogative speech portion data (7). A speech recognition device (20) applies a speech recognition processing to the interrogative speech portion data (7) to extract a keyword (9). A trend analysis device (25) analyzes the trend of the inquiry of customers by using the extracted keyword (9) and outputs the result as inquiry trend information (5).
