In this paper three different dialects of the same phrase for the voice data of spectrum analysis and comparison,we extract the three dialects of the pitch period,the frequency-weighted average in pitch period and the first formant average by using the software Praat and construct the three dialects of characteristic phalanx. Through the three dialects of the matrix eigenvalue and eigenvector of mathematical analysis,reveals the inherent law of dialects with the geographical changes in a dialect region.
