为什么我得到相同的结果，无论我是否更改文件？

Question

您好，我正在尝试使用以下 sdk：

https://github.com/watson-developer-cloud/python-sdk/blob/master/examples/speech_to_text_v1.py

为了得到一个wav文件的文字转录如下：

import json
from os.path import join, dirname
from watson_developer_cloud import SpeechToTextV1


speech_to_text = SpeechToTextV1(
    username='XXXXXXXXX',
    password='XXXXXXXXX',
    x_watson_learning_opt_out=False
)
print(json.dumps(speech_to_text.models(), indent=2))
print('I am using the spanish model for this test')
print(json.dumps(speech_to_text.get_model('es-ES_NarrowbandModel'), indent=2))

with open(join(dirname(__file__), '/Users/Downloads/python-sdk-master/examples/test.wav'),
          'rb') as audio_file:
    print(json.dumps(speech_to_text.recognize(
        audio_file, content_type='audio/wav', timestamps=True,
        word_confidence=True),
        indent=2))

问题是每次我运行请求如下：

python speech.py 

我得到了相同的结果，如果我更改参数中的文件名也没关系，我总是得到：

所以我想感谢支持来完成这个任务，

如果您要指定完全限定的文件路径，则不需要 join(dirname(__file__)。如果您想要的音频文件的路径不在相对路径中，我会尝试删除 join，但如果这是问题所在，我预计会出现文件未找到错误。
