So, Speech signal processing plays an important role in modern information society. With the development of digital audio processing technology, speech technology has been widely used in real life. Voice has more advantages than other forms of interactive. Then, this technology has become increasingly close to people's lives. Therefore, spectral analysis of speech signals has important significance. Keywords: Spectrum Analysis, Fast Fourier Transform, Java, Recording 摘要 I
