Text to Speech API got a ResultReason.Canceled result.

三轮的蹬 1

Hi Guys,

I have been using Speech-to-Text API for a while and it worked fine. But recently it just stopped working so I checked the result code and it showed:
result: SpeechSynthesisResult(result_id=293e54cd8473407c93bbea90d182aa85, reason=ResultReason.Canceled, audio_length=0)

I couldn't figure out the exact reason of it so I googled and I find a way to collect more log information of it.
255401-tts.log

The error message seems to be:
[742986]: 935ms SPX_TRACE_ERROR: apple_codec_adapter.cpp:104 Error decoding audio stream: -50

Does anyone of you know the exact reason of it and how to fix it? Thank you very much.

@三轮的蹬 Thanks for the question. Can you please add more details about the audio stream that you are trying.

Actually, it is the sample code:

   import azure.cognitiveservices.speech as speechsdk  
   from azure.cognitiveservices.speech.audio import AudioOutputConfig  
     
     
   def synthesize_to_speaker():  
       # Find your key and resource region under the 'Keys and Endpoint' tab in your Speech resource in Azure Portal  
       # Remember to delete the brackets <> when pasting your key and region!  
       speech_config = speechsdk.SpeechConfig(  
           subscription="da1a807f83fb446d88a6a5a360762cd0", region="eastasia")  
       speech_config.set_property(speechsdk.PropertyId.Speech_LogFilename, "LogfilePathAndName")  
       # In this sample we are using the default speaker  
       # Learn how to customize your speaker using SSML in Azure Cognitive Services Speech documentation  
       audio_config = AudioOutputConfig(use_default_speaker=True)  
       synthesizer = speechsdk.SpeechSynthesizer(  
           speech_config=speech_config, audio_config=audio_config)  
       r = synthesizer.speak_text("Enter some text to synthesize.")  
       print("result:", r)  
     
     
   synthesize_to_speaker()
