A Clinical Study: Does the voice influence how others perceive your appearance?

I ran and analyzed a clinical vocal study to determine if a person’s voice influences how others perceive their appearance. In this experiment my focus group test participants consisted of 10 people, all single men.
I split these 10 into two groups labeling them ‘Group A’ and ‘Group B.’
My testing subject is a female voice actress. I took a photo of her and edited the woman’s photo to be unattractive using Photoshop. Then I had the voice actress record two different speaking voices to use for playback in this experiment.
The first voice she recorded is a good voice, which is a clear sounding and beautiful. The second voice she recorded is a bad voice, which sounds hoarse and husky.
I let ‘Group A’ listen to the first voice (the good voice) and ‘Group B’ listen to the second voice (the bad voice). Following their observation I evaluated them by asking them this question, “This is a photo of the woman who was singing, in your opinion, do you think the woman in the photo looks attractive?”
Regarding the results of Group A (the group that heard the good voice), 2 people answered: “She looks so attractive.” 2 more people answered: “She is neither attractive nor not attractive.” The final participant from that group answered: “I don’t think she is attractive.”
On the other hand, regarding the results of Group B (the group that heard the bad voice), all 5 participants answered, “I do not think she looks attractive.”
Despite the fact that they all saw a photo of same woman, both group’s answers were different. This is because the voice significantly influences how others perceive a person’s appearance.
So the majority of both vocal study group participants were clearly influenced by the quality of the voice they heard when basing an opinion about that person’s appearance.
In conclusion, I believe that anybody can change how other people view their appearance based solely on the underlying factor of a good speaking voice.
