Abstract FREQUENTLY heard are remarks which imply that when one has a cold one's speech sounds "different." This commonly alleged difference has evidently been so generally accepted that scientific investigators have not been stimulated to evaluate it; at least, a search that I made through the literature revealed few observations other than what might be furnished by any man on the street. I felt that some attempt should be made to obtain more definite information about the influence a cold might have on speech not only because of the frequency of opportunities that any such relationship has to exert itself, but also because information concerning it might add to the understanding of other voice problems. By way of initiating such an attempt, a number of victims of coryza were found and several possible effects of that condition on their speech were studied. The purpose of this paper is to report findings References 1. Dr. Calvin J. Curts (MC) U.S.N. furnished the evaluations. 2. Haagen, C.

Since the second recording of each subject was made within several minutes of the first, it is possible that there was an adaptation effect which diminished the variation among the means. 5. Chi-square values were 1.34 (P = 0.25) for the first discrepancy mentioned and 2.16 (P = 0.15) for the second. 6. Nasal-including words—i. e., those containing m, n or ng—constituted about 35 per cent of the total in most of the lists used. 7. Vrw/Vrws = 1.77 (P > 0.05). 8. Vr/Vrs = 2.19 (P > 0.05). 9. Vw/Vws = 8.92 (P < 0.01). 10. Mason, H.

Of possible interest here is the fact that the number of paired speech samples correctly judged by a listener in one comparison was not a good indication of the number he might judge right in the other comparison (r = −0.061). 13.
