如何在 Azure 中返回简单的时间戳输出？

Question

我正在尝试减少从我正在使用的 Azure 语音到文本模型中获取的数据。第 21 行是指定输出格式的地方，我已将其更改为“简单”，但我仍然得到详细的输出。我使用的代码是：

using System;
using System.Threading.Tasks;
using Microsoft.CognitiveServices.Speech;
using Microsoft.CognitiveServices.Speech.Audio;

namespace NEST
{
class Program
{


    static void Main(string[] args)
    {
        var key = "";
        var region = "";
        var audioFilePath = @"C:/Users/MichaelSchwartz/source/repos/AI-102-Process-Speech-master/transcribe_speech_to_text/media/narration.wav";
        var speechConfig = SpeechConfig.FromSubscription(key, region);

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

        var stopRecognition = new TaskCompletionSource<int>();

        // Calls the audio file
        var audioConfig = AudioConfig.FromWavFileInput(audioFilePath);
        var recognizer = new SpeechRecognizer(speechConfig, audioConfig);


        //Display Recognized
        recognizer.Recognized += (s, e) =>
        {
            if (e.Result.Reason == ResultReason.RecognizedSpeech)
            {
                Console.WriteLine($"RECOGNIZED :{e.Result.Properties.GetProperty(PropertyId.SpeechServiceResponse_JsonResult)}");
            }
            else if (e.Result.Reason == ResultReason.NoMatch)
            {
                Console.WriteLine($"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 });

        do
            {
                Console.WriteLine("Press Enter to stop");
            } while (Console.ReadKey().Key != ConsoleKey.Enter);

            // Stops recognition.
            recognizer.StopContinuousRecognitionAsync().ConfigureAwait(false);

    }
}
}

返回什么时间单位？偏移量：173800000？该模型运行几秒钟，而不是几小时。 “偏移”和“持续时间”是什么意思？

有没有办法在消息级别而不是单词级别添加时间戳？或者至少是一种专注于指示每个话语何时开始的词级数据子集的方法？我正在转录更长的话语，而且是几个小时的音频。

Session stopped event.

另外，为什么输出重复结果 5 次？我希望尽可能地减少它以进行数据分析。有没有办法将度量单位更改为对用户更友好的单位，例如秒？

Answer 1

第一季度：

为什么输出重复5次？

其实你可以通过问题从STT FAQ找到答案：

我得到了每个短语的多个结果以及详细的输出格式。 我应该使用哪一个？

在设计上，您可以在NBest 的JSON 响应中获得多个不同置信度分数的结果，默认情况下，系统会选择第一个作为显示结果。您可以根据需要选择结果，例如置信度得分最高的结果。

第二季度：

有没有办法将测量单位更改为更易于使用的单位，例如秒？

事实上，Azure 没有提供任何进一步的方法来使用结果。但是我根据你的代码写了一个简单的demo：

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 = "";
            var 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 + " duraction:" + 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 });


        }

    }

    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; }
    }
}

结果：

如果指定时间长的.wav文件，结果会分成多方。
