使用 python 进行基于说话人识别的项目，并在查找MFCC.

Traceback (most recent call last):
File "neh1.py", line 10, in <module>
    complexSpectrum = numpy.fft(signal)
TypeError: 'module' object is not callable

这是代码的一部分：

import numpy
from scipy.fftpack import dct
from scipy.io import wavfile
sampleRate, signal = wavfile.read("/home/neha/Audio/b6.wav")
numCoefficients = 13 # choose the sive of mfcc array
minHz = 0
maxHz = 22.000
complexSpectrum = numpy.fft(signal)
powerSpectrum = abs(complexSpectrum) ** 2
filteredSpectrum = numpy.dot(powerSpectrum, melFilterBank())
logSpectrum = numpy.log(filteredSpectrum)
dctSpectrum = dct(logSpectrum, type=2) 

会出现什么问题呢？
