使用IBM Watson Speech To Text未获得预期结果

Question

当尝试在标准IBM Watson S2T型号上测试mp3文件时，我得到以下输出：

<bound method DetailedResponse.get_result of <ibm_cloud_sdk_core.detailed_response.DetailedResponse object at 0x00000250B1853700>>

这不是一个错误，但也不是我想要的输出。

这是我的代码：

api = IAMAuthenticator(api_key)
speech_to_text = SpeechToTextV1(authenticator=api)
speech_to_text.set_service_url(url)
with open(mp3-file, "rb") as audio_file:
result = speech_to_text.recognize(
model='de-DE_BroadbandModel', audio=audio_file, content_type="audio/mp3"
).get_result
print(result)

我对这个话题很陌生，还没有真正弄清楚参数是什么。我希望有一个像一样的输出

{'result': [...]}

我遵循了本教程。我做错了什么？

Answer 1

get_result是一个方法，所以你需要调用它。你打印出的是方法，而不是调用它。因此你的输出显示

<bound method DetailedResponse.get_result ...

几个支架应该可以修复它。

with open(mp3-file, "rb") as audio_file:
result = speech_to_text.recognize(
model='de-DE_BroadbandModel', audio=audio_file, content_type="audio/mp3"
).get_result()

Answer 2

以下是使用示例audio_file2.mp3为我工作的代码

import json
from os.path import join, dirname
from ibm_watson import SpeechToTextV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator
authenticator = IAMAuthenticator('{api_key}')
speech_to_text = SpeechToTextV1(
authenticator=authenticator
)
speech_to_text.set_service_url('{url}')
with open(join(dirname(__file__), './.', 'audio-file2.mp3'),
'rb') as audio_file:
speech_recognition_results = speech_to_text.recognize(
audio=audio_file,
content_type='audio/mp3',
word_alternatives_threshold=0.9
).get_result()
print(json.dumps(speech_recognition_results, indent=2))

步骤：

1. 创建Watson语音转文本服务后
2. 用语音到文本服务凭据替换Python代码中的{url}和{api_key}
3. 将带有代码的文件保存为speech-to-text.py
4. 从命令提示符或终端，运行pip install ibm-watson，然后运行python speech-to-text.py，可以看到类似于下面所示的结果
