RecognizeOnceAsync finish before audio is finished

Question

Hi, i'm using a wav file that has a little silence. The method RecognizeOnceAsync stops converion to text until that point. How can i force the method to listen ALL the audio?

This is my code:
async static Task<string> RecognizeFromMic(SpeechConfig speechConfig)
{
using var audioConfig = AudioConfig.FromWavFileInput("Ejemplo de pedido.wav");
using var recognizer = new SpeechRecognizer(speechConfig, audioConfig);

            var result = await recognizer.RecognizeOnceAsync();
            switch (result.Reason)
            {
                case ResultReason.RecognizedSpeech:
                    Console.WriteLine($"RECOGNIZED: Text={result.Text}");
                    break;
                case ResultReason.NoMatch:
                    Console.WriteLine($"NOMATCH: Speech could not be recognized.");
                    break;
                case ResultReason.Canceled:
                    var cancellation = CancellationDetails.FromResult(result);
                    Console.WriteLine($"CANCELED: Reason={cancellation.Reason}");

                    if (cancellation.Reason == CancellationReason.Error)
                    {
                        Console.WriteLine($"CANCELED: ErrorCode={cancellation.ErrorCode}");
                        Console.WriteLine($"CANCELED: ErrorDetails={cancellation.ErrorDetails}");
                        Console.WriteLine($"CANCELED: Did you update the subscription info?");
                    }
                    break;
            }
            return result.Text;
        }

Thanks

No, i have an audio wav file. I do not need continous as i do not want to show progress or listen all time.

The docs are clear :

The end of a single utterance is determined by listening for silence at the end, or until a timeout period has elapsed

The question is how to set this timeout or threshold silence....

I have an azure suscription and i would like to know if there is some sort of option to set more time. I'm subscribed to S0 Standard...

Thanks

I've changed the code to use your StartContinuousRecognitionAsync. and now all the wav is processed.

But, very strange. Look at my code:

recognizer.Recognizing += (s, e) =>
                    {
                        text = e.Result.Text;

                        Console.WriteLine($"RECOGNIZING: Text={e.Result.Text}");

                        Dispatcher.Invoke(()=>this.ctText.Text=e.Result.Text);
                    };

When recognition arrives at 30 s the variable text holds the text converted.
But THEN, e.Result.Text starts again!!!!

So, if full text should be 'hello i'm your friend and i would like to .............. Glad to see you again'

At second 29, text is:

text=hello i'm your friend and i would like to....

Then at second 30 text is:

text=Glad to see you again

Do have my account some sort of limitation= That's not normal...
