Azure Speech to Text 在 3-4 分钟后停止工作

问题描述

我正在尝试转录大约 10-20 分钟的音频文件。 Azure Speech to Text 在大约 3 分 20 秒后停止。我正在使用连续识别，但我不确定问题是什么。这篇文章中的解决方案现已失效链接：

Azure Speech to Text stops working after 3 to 4 minutes in Android SDK Version 1.2.2

我的代码是：

using Microsoft.CognitiveServices.Speech;
using Microsoft.CognitiveServices.Speech.Audio;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Linq;

namespace STTwithTime
{
class Program
{


    static void Main(string[] args)
    {
        var key = "subscriptionkey";
        var region = "region";
        var audioFilePath = @"";
        var speechConfig = SpeechConfig.FromSubscription(key,region);

        // Generates timestamps
        speechConfig.RequestWordLevelTimestamps();
        speechConfig.OutputFormat = OutputFormat.Detailed;

        var stopRecognition = new taskcompletionsource<int>();

        var audioConfig = AudioConfig.FromWavFileInput(audioFilePath);
        var recognizer = new SpeechRecognizer(speechConfig,audioConfig);

        //display Recognized
        recognizer.Recognized += (s,e) =>
        {
            if (e.Result.Reason == ResultReason.RecognizedSpeech)
            {
                
                var result = JsonConvert.DeserializeObject<Result>(e.Result.Properties.GetProperty(PropertyId.SpeechServiceResponse_JsonResult));
                
                var maxConfidenceValue = result.NBest.Max(item => item.Confidence);
                var maxConfidence =  result.NBest.Find(item => item.Confidence == maxConfidenceValue);
                Console.WriteLine("================================");
                Console.WriteLine("Confidence:"+maxConfidence.Confidence);
                Console.WriteLine("RECOGNIZED :" + maxConfidence.display);
                Console.WriteLine("Duration: :" + Convert.Todouble(result.Duration) / 10000000);
                Console.WriteLine("Words:");
                foreach (var word in maxConfidence.Words) {
                    Console.WriteLine(word.word + "=> offset:" + Convert.Todouble(word.Offset) / 10000000 + " duration:" + Convert.Todouble(word.Duration) / 10000000);
                }
                
            }
            else if (e.Result.Reason == ResultReason.NoMatch)
            {
                Console.WriteLine($"NOMATCH: Speech Could not be recognized.");
            }
        };

        recognizer.Canceled += (s,e) =>
        {
            Console.WriteLine($"CANCELED: Reason={e.Reason}");

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

            stopRecognition.TrySetResult(0);
        };

        recognizer.SessionStopped += (s,e) =>
        {
            Console.WriteLine("\n    Session stopped event.");
            stopRecognition.TrySetResult(0);
        };

        recognizer.StartContinuousRecognitionAsync().GetAwaiter().GetResult();

        // Waits for completion. Use Task.WaitAny to keep the task rooted.
        Task.WaitAny(new[] { stopRecognition.Task });

        // Keeps external console from closing too quickly
        string v = Console.ReadLine();


    }

}

public class Word
{
    public int Duration { get; set; }
    public int Offset { get; set; }
    public string word { get; set; }
}

public class NBest
{
    public double Confidence { get; set; }
    public string display { get; set; }
    public string ITN { get; set; }
    public string Lexical { get; set; }
    public string MaskedITN { get; set; }
    public List<Word> Words { get; set; }
}

public class Result
{
    public string displayText { get; set; }
    public int Duration { get; set; }
    public string Id { get; set; }
    public List<NBest> NBest { get; set; }
    public int Offset { get; set; }
    public string RecognitionStatus { get; set; }
}
}

我该如何解决这个问题？我需要转录整个音频文件。有什么解决方法吗？提前致谢。
