SpeakSsmlAsync返回USP错误，超时以获取第一个音频块

问题描述

调用SpeakSsmlAsync（Microsoft Speech SDK）时，返回以下错误消息：

CANCELED: 
Reason=Error,ErrorCode=NoError,ErrorDetails=[USP error,timeout to get the first audio chunk.]

using (var stream = AudioOutputStream.CreatePushStream(callback))
{
    // Creates a speech synthesizer using audio stream output.
    using (var streamConfig = AudioConfig.FromStreamOutput(stream))
    {
        using (var synthesizer = new SpeechSynthesizer(config,streamConfig))
        {
            // Receives a text from console input and synthesize it to pull audio output stream.
            using (var result = await synthesizer.SpeakSsmlAsync(text))
            {
                if (result.Reason == ResultReason.SynthesizingAudioCompleted)
                {
                    logger.Info($"Speech synthesized for text [{text}],and the audio was written to output stream.");
                }
                else if (result.Reason == ResultReason.Canceled)
                {
                    var cancellation = SpeechSynthesisCancellationDetails.FromResult(result);

                    if (cancellation.Reason == CancellationReason.Error)
                    {
                        Console.WriteLine($"CANCELED: Reason={cancellation.Reason}," +
                            $"ErrorCode={cancellation.ErrorCode}," +
                            $"ErrorDetails=[{cancellation.ErrorDetails}]");
                    }
                }
            }
