Python 中的 IBM Watson Speech to Text 在使用模型参数时给出 404

Question

我正在使用 Python 测试 IBM Watson Speech to Text 的使用。我能够成功地测试用英语转录音频，但是当我输入模型参数以更改我的语言的语言模型时，会出现 404 未找到错误。我已经多次查看 IBM page 解释模型参数的使用，但我不明白缺少什么。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()

错误信息：

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

Answer 1

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()

把我用过的完整代码贴出来供大家参考

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,
        content_type='audio/mp3',
        word_alternatives_threshold=0.9,
        model='fr-FR_BroadbandModel'
    ).get_result()
print(json.dumps(speech_recognition_results, indent=2))
