  • Abstract
  • Look Inside

 It is well know that voice theraphy is very effective in some cases of vocal cord polyp, polypoid degeneration and singer's nodule. Howevere, we have little knowledge about the total speaking time in a day, the speaking ratio per hour and the sound level during speaking in each patient. If these parameters are detected easily, it must become clear how the speaking time or pattern relates to such a voice disorder or what instruction a doctor should give to a patient. Based on such thoughts, we devised a speech accumulator which counts the vibration time of the vocal cords by a small contact microphone attached on the neck. The speaking time in any sound level is shown as digital data at any time. This handy equipement was clinically applicated to 11 persons and was found very useful. The longest speaking time in a day was 182 minutes in a bus conductress and the shortest time was 33 minutes in an office clerk.
