使用模型参数时，Python中的IBM Watson Speech to Text提供404

如何解决使用模型参数时，Python中的IBM Watson Speech to Text提供404

我正在测试将IBM Watson Speech to Text与Python结合使用。我能够成功测试英语的音频转录，但是当我输入模型参数来更改我的语言的语言模型时，会出现404 not found错误。我已经看过IBM page多次，解释了model参数的用法，但我不明白缺少了什么。有人可以帮忙吗？

我的代码：

from ibm_watson import SpeechToTextV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator

api = IAMAuthenticator("my_credential")
speech_2_text = SpeechToTextV1(authenticator=api)

speech_2_text.set_service_url("https://api.us-south.speech-to-text.watson.cloud.ibm.com/instances/20a185d6-6953-4334-9cea-e9f5ebc2267d?model=fr-FR_broadbandModel")

with open("test.mp3","rb") as audio_file:
    result = speech_2_text.recognize(
    audio=audio_file,content_type="audio/mp3"
    ).get_result()

错误消息：

ibm_cloud_sdk_core\base_service.py",line 224,in send raise ApiException(ibm_cloud_sdk_core.api_exception.ApiException: Error: Not Found,Code: 404

解决方法

模型应作为recognize方法的一部分传递

speech_recognition_results = speech_to_text.recognize(
        audio=audio_file,content_type='audio/mp3',word_alternatives_threshold=0.9,model='fr-FR_BroadbandModel'
    ).get_result()

粘贴对我有用的完整代码供您参考

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,model='fr-FR_BroadbandModel'
    ).get_result()
print(json.dumps(speech_recognition_results,indent=2))
