Subject: male/female voice From: herzfeld <herzfeld(at)ALUM.MIT.EDU> Date: Sun, 5 Jan 2003 12:22:12 -0500Hello List, In a most interesting paper: "Study of variations in the male and female glottal wave Randall Monsen and Maynard Engebretson, JASA 1977 62(4) 981-991" these researchers from Central Institute for the Deaf found and published the very interesting result that the phase angle between the first and second harmonics (Figure 8) is very different in the male vs female glottal wave form. The differences they found generally amounted to 20 to 30 degrees. I have not been able to find any further work specifically on the phase differences between the first and second harmonics (or other harmonics) between the male and female glottal wave or in male and female speech! My interest in this area is because I have developed an algorithm which could be used as a good tool in this kind of application and will publish as soon as patent applications are submitted. If anyone knows of any work (published or unpublished) in male/female phase differences among the partials please let me know. -- Fred Herzfeld, MIT'54 78 Glynn Marsh Drive #59 Brunswick, Ga. 31525-0504 Tel: (912) 262-1276
