为什么自己录的音频（共6条，有中文或英文）都能识别，但是识别的结果都不正确。而样例音频都能正确识别。这是为什么呢？

恳请各位大神指点 多谢！

from aip import AipSpeechAPP_ID =''
API_KEY=''
SECRECT_KEY=''
client = AipSpeech(APP_ID,API_KEY,SECRECT_KEY)

filePath = 'C:/Users/Jackie_Lucy/Music/I love cn_cn.wav'

'''
Read audio file
'''
def get_file_content(filePath):

with open(filePath,'rb') as fp:

return fp.read()

# fp= open(filePath,'rb')
# return fp.read()

'''
Recognize the file
'''
result = client.asr(get_file_content(filePath),'wav',16000,{'dev_pid':'1737',}) # 1536:普通话 1737：English

print(result.get('result')[0])
