I was unable to find a video of this speech. I could only find a written transcript of what Alice Walker said on April 11, 1987 at Spelman College in Atlanta. Having only a written transcript of this speech makes analyzing it a bit more difficult because the written speech is incapable of delivering to the reader the pieces of non-verbal communication that Alice Walker used during her delivery of the message. We can't hear her usage of vocal variety. We can't see her usage of eye contact or platform movement. A great deal of what makes a speech an excellent speech is non-verbal communication.
What you can successfully analyze in Walker's speech is her introduction and how she is able to draw her audience in while establishing her own credibility. A speaker has to convince audiences of various things, and speakers can use logos, pathos, and ethos. Ethos is the speaker's credibility, and Walker uses it very much to her advantage. She lets her audience know right away that she understands them and their situation. Walker attended Spelman College. She knows what it is like to be a student there and listen to speakers like herself. Audiences are drawn to respect and listen to the speaker more closely if they feel a sort of kinship with the speaker, and Walker draws that out of the audience right away.
She continues to speak about her own personal experiences, but her final paragraph asks the audience to take ownership of her message and apply it to their lives. This is a wonderful conclusion because a speaker's conclusion should always try to steer an audience into believing something or doing something, and Walker does a nice job of pushing her audience to believe that joy in creation can always be found "within and about the self."
