title: [Comparison of the results obtained through manual and automatic phonetogram].
abstract: BACKGROUND
  The phonetogram (F) is the graphic representation of a person phonatory potential. The F carried out with a sonometer and a frequency analyser is what is called "manual phonetogram" (MPh), and the one obtained by means of a computer is called the "automatic phonetogram" (APh).
  
  
  METHODS
  We have carried out in 12 lyrical singers a standard MPh and an APh with the program Dr. Speech Science 3.0.
  
  
  RESULTS
  It was showed a significant difference with a p < 0.0005 in 14 of the 15 measures compared, and a p < 0.05 for the other one, being in general the results of the automatic test different from those of the manual in excess, with a correlation between the results obtained through both methods.
  
  
  CONCLUSIONS
  The APh obtained with the program Dr. Speech Science 3.0 is a faster and easier way to obtain the phonetogram than the one used to obtain the MPh, showing however big differences in excess compared with the ones of the MPh in all the usual phonetometric parameters.
