c# - VSCode 发生异常 : CLR/System. ApplicationException

Question

我正在 VSCode 中使用 C# 开发语音转文本模型。该模型正确转录第一个文件。当我添加新文件并尝试转录时，出现以下错误:

发生异常:CLR/System.ApplicationExceptionSystem.Private.CoreLib.dll 中发生“System.ApplicationException”类型的异常，但未在用户代码中处理:“错误代码异常:0x8 (SPXERR_FILE_OPEN_FAILED)”在 Microsoft.CognitiveServices.Speech.Internal.SpxExceptionThrower.ThrowIfFail(IntPtr hr)在 Microsoft.CognitiveServices.Speech.Recognizer.FromConfig(GetRecognizerFromConfigDelegate fromConfig、SpeechConfig 语音配置、AudioConfig 音频配置)在 Microsoft.CognitiveServices.Speech.SpeechRecognizer..ctor(SpeechConfig 语音配置，AudioConfig 音频配置)在 C:\Users\admin\source\repos\AI-102-Process-Speech-master\transcribe_speech_to_text\csharp\NEST\Program.cs 中的 NEST.Program.d__1.MoveNext() 处:第 26 行在 System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(任务任务)在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(任务任务)在 System.Runtime.CompilerServices.TaskAwaiter.GetResult()在 C:\Users\admin\source\repos\AI-102-Process-Speech-master\transcribe_speech_to_text\csharp\NEST\Program.cs 中的 NEST.Program.d__0.MoveNext() 处:第 12 行

await RecognizeSpeechAsync();部分是异常发生的地方(第 12 行)。第 26 行使用 (var recognizer = new SpeechRecognizer(config, audioInput))。

我的代码是:

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

namespace NEST
{
    class Program
    {
        static async Task Main(string[] args)
        {
            await RecognizeSpeechAsync();
        }

        static async Task RecognizeSpeechAsync()
        {
            // Configure the subscription information for the service to access.
            // Use either key1 or key2 from the Speech Service resource you have created
            var config = SpeechConfig.FromSubscription("subscriptionkeyx", "regionx");

            // Setup the audio configuration, in this case, using a file that is in local storage.
            using (var audioInput = AudioConfig.FromWavFileInput("C:/Users/admin/source/repos          /AI-102-Process-Speech-master/transcribe_speech_to_text/media/whatstheweatherlike.wav"))

            // Pass the required parameters to the Speech Service which includes the configuration
            // and the audio file name that you will use as input
            using (var recognizer = new SpeechRecognizer(config, audioInput))
            {
                Console.WriteLine("Recognizing first result...");
                var result = await recognizer.RecognizeOnceAsync();

提前致谢。

SPXERR_FILE_OPEN_FAILED 表示文件未找到或打开失败。

我在文件路径中添加了一个空格来重现您的问题。 (您正在使用绝对路径。)

错误路径:

C:/Users/Administrator/source/repos   /vscodeConsole/narration.wav

正确路径

C:/Users/Administrator/source/repos/vscodeConsole/narration.wav

隐私

查看错误信息，第26行附近有错误。

You can test with my sample code 。如果运行正常，那就是你的代码有问题。我初步判断是你的文件路径附近的代码出现异常。

如果我的示例代码无法正常运行，可能是由于安装了 VSCode(包括 Extension)或 dotnet core 导致的，需要进一步排查。
