I am interested in the phenomenon of h-dropping of the initial h. Are there any studies showing what vowels would be most likely to cause the h to be dropped?
I did find one essay by Angelika Lutz in which she notes that certain surrounding phonemes will have an effect on the likelihood of the h being dropped, but I do not think she addresses the effect of the following vowel sound. The essay was in Luick Revisited, a collection of conference paper published in 1985.
