The 1906 LDS large-print edition accidentally replaced the present-tense speak with the pasttense spake. Perhaps the typesetter was influenced by the preceding clause near the beginning of the verse that reads “the angel of the Lord spake unto me”. Theoretically, either tense would work in this passage, but here the earliest textual sources all support the present-tense speak.
Summary: Maintain the present-tense speak in 1 Nephi 13:34, the reading of the original manuscript.
