PHONETIC TIME AXIS CONVERSION DEVICE |
| 摘要 |
PURPOSE: To provide a phonetic time axis conversion device capable of converting an acoustic signal into a signal having the speech speed more than a reproducing speed and less than a recording time while holding an interval at the recording time when an acoustic signal is reproduced at the speed or below at the recording time. CONSTITUTION: A sound M-multiple speed (0<M<1) reproduced from a recording/reproducing part 101 is written in an input buffer 103 after converted into a digital signal by an A/D converter at a period T/M. This signal is sound/ silence-decided by a sound/silence decision part 104. A time axis control part 105 revises an elongation ratio according to the decision result of sound/silence parts to perform time axis elongation for the data read out from the input buffer 103 and to write in an output buffer. A remaining data monitor part 109 measures the remaining data stored without being read out from the output buffer to a D/A converter to impart them to an elongation ratio control part 110. The elongation ratio control part decides independently the elongation ratios of a sound part to a silence part by a conversion rule answering to the remaining data and silence contents to impart to the time axis control part. |
