需要安装pyaudio库。

直接上代码：

import pyaudio
import wave

AUDIO_FILE = '录音文件.wav'

def get_audio(filepath, audio_time): #录音

CHUNK = 256  
FORMAT = pyaudio.paInt16  
CHANNELS = 1                # 声道数  
RATE = 16000                # 采样率  
RECORD\_SECONDS = audio\_time  
WAVE\_OUTPUT\_FILENAME = "录音文件.wav"  
p = pyaudio.PyAudio()

stream = p.open(format=FORMAT,  
                channels=CHANNELS,  
                rate=RATE,  
                input=True,  
                frames\_per\_buffer=CHUNK)

print("\*"\*10, "开始录音：请在%d秒内输入语音"% (audio\_time))  
frames = \[\]  
for i in range(0, int(RATE / CHUNK \* RECORD\_SECONDS)):  
    data = stream.read(CHUNK)  
    frames.append(data)  
print("\*"\*10, "录音结束\\n")

stream.stop\_stream()  
stream.close()  
p.terminate()

wf = wave.open(WAVE\_OUTPUT\_FILENAME, 'wb')  
wf.setnchannels(CHANNELS)  
wf.setsampwidth(p.get\_sample\_size(FORMAT))  
wf.setframerate(RATE)  
wf.writeframes(b''.join(frames))  
wf.close()

if __name__ == '__main__':
get_audio(AUDIO_FILE,10)
