Azure API Not Working(sorry for the title I have no idea what's wrong)-CodePudding

As I said already sorry for the title. I have never worked with Azure API and have no idea what is wrong with the code, as I just copied from the documentation and put in my information.

Here is the code:

from azure.cognitiveservices.speech import AudioDataStream, SpeechConfig, SpeechSynthesizer, SpeechSynthesisOutputFormat
from azure.cognitiveservices.speech.audio import AudioOutputConfig

speech_config = SpeechConfig(subscription="ImagineHereAreNumbers", region="westeurope")


speech_config.speech_synthesis_language = "en-US"
speech_config.speech_synthesis_voice_name = "ChristopherNeural"

audio_config = AudioOutputConfig(filename=r'C:\Users\TheD4\OneDrive\Desktop\SpeechFolder\Azure.wav')

synthesizer = SpeechSynthesizer(speech_config=speech_config, audio_config=audio_config)
synthesizer.speak_text_async("A simple test to write to a file.")

Well as I run this I get no error and in fact, get in my desired folder a .wav file, but this file has 0 bytes and it looks corrupted.

Now here is why I have no idea of what's wrong because if I remove this

speech_config.speech_synthesis_language = "en-US"
speech_config.speech_synthesis_voice_name = "ChristopherNeural"

So it becomes this

from azure.cognitiveservices.speech import AudioDataStream, SpeechConfig, SpeechSynthesizer, SpeechSynthesisOutputFormat
from azure.cognitiveservices.speech.audio import AudioOutputConfig

speech_config = SpeechConfig(subscription="ImagineHereAreNumbers", region="westeurope")


audio_config = AudioOutputConfig(filename=r'C:\Users\TheD4\OneDrive\Desktop\SpeechFolder\Azure.wav')

synthesizer = SpeechSynthesizer(speech_config=speech_config, audio_config=audio_config)
synthesizer.speak_text_async("A simple test to write to a file.")

It now works all of the sudden, but with what I assume to be the basic/common voice.

So here is my question: how do I choose a voice that I want(btw is this one "en-US-JennyNeural" style="customerservice" or something among these lines)

Thank You in advance!

CodePudding user response：

ChristopherNeural is not a valid voice name. The actual name of the voice is en-US-ChristopherNeural.

speech_config.speech_synthesis_voice_name = "en-US-ChristopherNeural"

This is well-documented on the Language support page of the Speech services documentation.

For other, more fine-grained control over voice characteristics, you'll require the use of SSML as outlined in text-to-speech-basics.py.
