title: [Analysis of results of fundamental frequency and voice parameter in healthy young people].
abstract: OBJECTIVE
  To study and analyzing the parameter values of voice in normal healthy young people.
  
  
  METHODS
  In present paper, voice quality of 153 cases were collected and analyzed with Dr. Speech software.
  
  
  RESULTS
  Jitter was (0.18 +/- 0.07)%, Shimmer (1.60 +/- 0.74)%, HNR (Harmonics-to-Noise Ratio) (25.34 +/- 3.12) dB, SNR (Signal-to-Noise Ratio) (25.39 +/- 3.09) dB and NNE (Normalized Noise Energy(-16.95 +/- 3.57) dB. Average of fundamental frequency in male was (160.81 +/- 24.27) Hz, in female was (297.42 +/- 35.89) Hz and in all was (206.35 +/- 70.77) Hz. At the same time, the results of some correlative parameter about voice was taken.
  
  
  CONCLUSIONS
  We considered that there were significant differences between gender about fundamental frequency in parameter values of voice. Three formant produced at 4.5 times, 8.64 times, 17.04 times of the fundamental frequency in male, at 2.07 times, 4.96 times, 7.28 times in female. This data was usefulness to evaluate voice results of normal or abnormal.
