I am trying to use IBM watson api for text to speech service. The service works if I use curl command but when I try to use the srrvice using Python SDK, It throws me below error.

Traceback (most recent call last): File "/anaconda3/lib/python3.6/site-packages/ibm_cloud_sdk_core/base_service.py", line 234, in send response.status_code, error_message, http_response=response) ibm_cloud_sdk_core.api_exception.ApiException: Error: Forbidden, Code: 403 Method failed with status code 403: Forbidden

Below is the curl command

curl -X GET -u "apikey:myapiKey" --output hello_world.wav "https://api.eu-de.text-to-speech.watson.cloud.ibm.com/text-to-speech/api/v1/synthesize?accept=audio/wav&text=Hallo%20Welt&voice=de-DE_DieterVoice"

Below is the python code

from ibm_watson import TextToSpeechV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator


from ibm_watson import ApiException
import json

IBM_API_ENDPOINT = "https://api.eu-de.text-to-speech.watson.cloud.ibm.com/text-to-speech/api/v1/synthesize"


IBM_TTS_API_KEY = "myAPIKey"

authenticator = IAMAuthenticator(IBM_TTS_API_KEY)
text_to_speech = TextToSpeechV1(authenticator=authenticator)
text_to_speech.set_service_url(IBM_API_ENDPOINT)


try:
    with open('IBM.wav', 'wb') as audio_file:
        audio_file.write(text_to_speech.synthesize("Hallo world", voice='de-DE_DieterVoice', accept='audio/wav').get_result().content)

except ApiException as ex:
    print("Method failed with status code " + str(ex.code) + ": " + ex.message)

Check the Current usage ( of 10000 Thousand char). I had the same issue when I reached the maximum limit of characters per month.

This will because you are are tacking the method and the version at the end of the endpoint. As you are using the Python SDK for IBM-Watson the SDK take care of applying the method when you invoke synthesize. Consequently your endpoint should only be:

IBM_API_ENDPOINT = "https://api.eu-de.text-to-speech.watson.cloud.ibm.com"

Check the API documentation for further details - https://cloud.ibm.com/apidocs/text-to-speech/text-to-speech?code=python#service-endpoint
