No module named speexdsp

I am using ReSpeaker 6-Mic with Raspberrypi 4B,according to the WIKI https://wiki.seeedstudio.com/ReSpeaker_6-Mic_Circular_Array_kit_for_Raspberry_Pi/#doa-with-keywords,when I run "python aec_ns_kws_doa.py "(~/voice-engine/examples/respeaker_6mic_array_for_pi/),the following problems arise:

Traceback (most recent call last):
File “aec_ns_kws_doa.py”, line 11, in
from voice_engine.ec import EC
File “/home/pi/.local/lib/python2.7/site-packages/voice_engine/ec.py”, line 17, in
from speexdsp import EchoCanceller
File “build/bdist.linux-armv7l/egg/speexdsp/init.py”, line 3, in
ImportError: No module named speexdsp

I try to re-install speexdsp module,but it doesn’t work,the above error still appears.
‘’‘
sudo apt install libspeexdsp-dev
git clone https://github.com/xiongyihui/speexdsp-python.git
cd speexdsp-python
python setup.py install
’‘’

Does anyone encounter this problem?How to solve it?
