Wav files generated are 0kb in size with no error

Question

Wav files generated are 0kb in size with no error

Zack T 0

I have been using this small script for weeks to generate wav audio files. However, yesterday, all the wav files that are generated have a 0kb file size. I have access to the directory that the file is written in and also it doesn't matter if it is an .mp3 or .wav file the created file always has 0kb size. I am using the free tier in azure. Could I have hit a limit? I am not sure why all of a sudden it will no longer generate the file.

using Microsoft.CognitiveServices.Speech.Audio;
using Microsoft.CognitiveServices.Speech;

namespace TextToSpeech
{
    class Program
    {
        static async Task Main()
        {
            await SynthsizeAudioAsync();
        }

static async Task SynthsizeAudioAsync()
{
    var config = SpeechConfig.FromSubscription("***", "***");
    config.SpeechSynthesisVoiceName = "en-US-ChristopherNeural";

    AudioConfig audioConfig = AudioConfig.FromWavFileOutput("***");
    using var synthesizer = new SpeechSynthesizer(config, audioConfig);


    await synthesizer.SpeakTextAsync("Hello world!");
}

}

@Zack T If you have exhausted all the limits of your free tier then you shouldn't be able to generate an audio file using other means like the speech studio or cli or REST API. You should also see the appropriate error code if request fails due to quota.

Could you try and check if the same issue is seen with other options?

I do not see an issue with the code snippet mentioned above, you might want to also check the usage of your resource through metrics and then change the pricing tier to standard and run the same script to see if audio is generated.

Hi, I have the same error, and I have my licenses able to generate the file.

Just the lenght of the string I think is too big for the process,

Would you please recommend me a solution?

Thank you!

thats my code:

  StringBuilder textToSpeech = new StringBuilder();
  textToSpeech.Append("LongTexttttttttttttttttttttttttttttttttttttttt (about 70000 characters\r\n");
  var speechConfig = SpeechConfig.FromSubscription(speechKey, speechRegion);
  speechConfig.SpeechSynthesisVoiceName = "es-MX-BeatrizNeural";
  using var audioConfig = AudioConfig.FromWavFileOutput(@"C:\TextoLibros\Prueba1.wav");
  using var speechSynthesizer = new SpeechSynthesizer(speechConfig, audioConfig);
  await speechSynthesizer.SpeakTextAsync(textToSpeech.ToString());
