Statistical survey of female pure vowel formants in Chinese (Putonghua)

In order to investigate the group characteristics of the pure vowel formants in Chinese (Putonghua), 90 female samples were tested. The formants were measured using LPC method. The averaged values and deviations of formants were given with statistical meaning. The results show the difference from the measurements done by other researchere in last century. For all pure vowels, F4/F3 and F5/F4 are generally around 1.4. For the discrimination of pure vowels, F2/F1 and F3/F2 are possibly the two new parameters besides the three lowest formants.
