Final answer:
The first voice speaking to Pi in 'Life of Pi' is the figure on the saddle of rock.
Step-by-step explanation:
The first voice speaking to Pi in the given reference is the figure on the saddle of rock. This voice is described as speaking with a trembling voice and a sense of pride. It is important to note that this is a fictional reference from the book 'Life of Pi' by Yann Martel. The first excerpt suggests a white man speaking with inextinguishable pride to an unseen audience on a mountain top, likely a fictional or poetic representation. The second excerpt talks about the voice of my heart in my side or the voice of the sea, which can be interpreted as an internal or metaphorical voice. The third excerpt references a work by Jacqueline Jones Royster, discussing the concept of recognizing other voices before your own, which may be metaphorical rather than a literal, discernible first voice.
