The marking position specifying unit 17 traces the time set in the retroactive time storage unit 119 from the location read out by the document / synthetic speech conversion unit 13 at the time when the DTMF signal is received by the DTMF reception unit 16, and the word, phrase, document Specify the marking range in units of. Here, the retroactive time indicates the time provided for specifying the location to be retroactively recorded for the time stored in the retroactive time storage unit 119 when DTMF is received.

  The marking document storage unit 18 stores the marked document. The proofread document storage unit 19 stores a document in which the marked portion of the marked document is proofread. The calibration site extraction unit 110 compares the marking document storage unit 18 and the proofread document storage unit 19 to extract a calibration site.

  The reading time difference detection unit 111 detects the reading time difference between the reading time of the calibration position and the marking position reading time near the calibration position every time the calibration position is detected. The reading time difference average time calculation unit 112 calculates the average time by dividing the cumulative value of the reading time difference detected by the reading time difference detection unit 111 by the number of calibration points.

  The reading interruption time setting unit 113 for each phrase unit interrupts reading for each word, phrase, reading point or phrase point of the document data, and sets a reading interruption time to be a silent time. When the average value calculated by the reading time difference average time calculation unit 112 is equal to or greater than a predetermined value, the reading interruption time setting unit 113 for each phrase unit sets the reading interruption time at the next reading of a document or reading of another document. Increase. On the other hand, when it is equal to or smaller than the predetermined value, the reading interruption time setting unit 113 for each phrase unit decreases the reading interruption time. Here, the interruption time indicates that during voice transmission, the voice transmission is interrupted for the time set in the interruption time setting unit 113 at the end of the word, the end of the phrase, before the punctuation mark, and before the punctuation mark, and the sound is silenced.

When the average value calculated by the reading time difference average time calculation unit 112 is equal to or greater than a predetermined value, the reading speed setting unit 114 for each phrase unit sets the reading speed at the next reading of the document or another document. Slow down. On the other hand, when the value is equal to or less than the predetermined value, the reading speed setting unit 114 for each phrase unit increases the reading speed.

  The document display processing unit 115 performs display processing for the documents in the created document storage unit 12, the marking document storage unit 18, and the proofread document storage unit 19. The retroactive time setting unit 116 sets the time for how far the marking is performed after receiving the DTMF signal. The reading method setting unit 117 sets whether to variably control the reading interruption time for each phrase, word, punctuation or phrase unit, or to variably control the reading speed.

  The retroactive time correction unit 118 adds or subtracts the average value of the reading time difference obtained by dividing the cumulative value of the reading time difference by the number of calibration points with respect to the time stored in the retroactive time storage unit 119. As a result, the retroactive time correction unit 118 learns the retroactive time so that the difference in reading time between the marking location and the subsequent calibration location is reduced. The retroactive time storage unit 119 stores the time set by the retroactive time setting unit 116 and the time corrected by the retroactive time correction unit 118.

  The document proofreading support apparatus 1 substitutes 0 for the proofreading location number N (S31). The document proofreading support apparatus 1 compares the pre-proofreading document and the proofread document from the beginning of the sentence, and extracts the proofreading part (S32). The document proofreading support apparatus 1 determines whether the end of the document is reached (S33). When YES in step 33, the document proofreading support apparatus 1 determines whether N exceeds 0 (S34). If YES in step 34, the document proofreading support apparatus 1 calculates an average value obtained by dividing the accumulated time difference by N (S36). The document proofreading support apparatus 1 determines whether the average value is a positive positive value or more (S37). When YES in step 37, the document proofreading support apparatus 1 increases the reading interruption time or / and decreases the reading speed or / and increases the retroactive time (S38).

  If NO in step 33, the document proofreading support apparatus 1 determines whether there is a proofreading part (S39). If YES in step 39, the document proofreading support apparatus 1 increments N (S41). The document proofreading support apparatus 1 calculates a reading time difference between the reading time of the proofreading part and the marking part reading time near the proofreading part (S42). The document proofreading support apparatus 1 accumulates the calculated reading time difference (S43).
