运行以下代码时出现语法错误。我已经研究过，语法错误是无缘无故发生的。语法错误是：文件“src/cloudspeech_demo.py”，第 49 行 elif 'repeat after me' in text: TabError: 缩进中制表符和空格的使用不一致 ^
这是我的代码：

if text is None:

else:
print('You said "', text, '"')
if 'turn on the light' in text:
led.set_state(aiy.voicehat.LED.ON)
elif 'turn off the light' in text:
led.set_state(aiy.voicehat.LED.OFF)
elif 'blink' in text:
led.set_state(aiy.voicehat.LED.BLINK)
elif 'repeat after me' in text:
to_repeat = text.replace('repeat after me', '', 1)
aiy.audio.say(to_repeat)
elif 'goodbye' in text:
break
if __name__ == '__main__':
main()
请告诉我我需要做什么来修复这个错误。
