Question

在我的代码中（如下），当我通过STT处理它时，它只给我整个音频的第一个字母/单词。

音频有“ A B C D E F”

我想念什么？

Imports Microsoft.CognitiveServices.Speech
Imports Microsoft.CognitiveServices.Speech.SpeechConfig
Imports Microsoft.CognitiveServices.Speech.Audio

Module Module1

    Sub Main()
        Dim SpeechConfig As SpeechConfig = FromSubscription("<CHANGED>", "eastus")
        Dim audioConfig As Audio.AudioConfig = Audio.AudioConfig.FromWavFileInput("<CHANGED>.wav")
        SpeechConfig.OutputFormat = Microsoft.CognitiveServices.Speech.OutputFormat.Detailed
        Dim recognizer As New SpeechRecognizer(SpeechConfig, audioConfig)
        Dim result = recognizer.RecognizeOnceAsync().Result

        Select Case result.Reason
            Case ResultReason.RecognizedSpeech
                Console.WriteLine($"RECOGNIZED: Text={result.Text}")
                Console.WriteLine($"    Intent not recognized.")
            Case ResultReason.NoMatch
                Console.WriteLine($"NOMATCH: Speech could not be recognized.")
            Case ResultReason.Canceled
                Dim cancellation = CancellationDetails.FromResult(result)
                Console.WriteLine($"CANCELED: Reason={cancellation.Reason}")

                If cancellation.Reason = CancellationReason.[Error] Then
                    Console.WriteLine($"CANCELED: ErrorCode={cancellation.ErrorCode}")
                    Console.WriteLine($"CANCELED: ErrorDetails={cancellation.ErrorDetails}")
                    Console.WriteLine($"CANCELED: Did you update the subscription info?")
                End If
        End Select

    End Sub

End Module

此外，如果您知道在哪里可以获得更详细的STT数据，我将不胜感激。我正在寻找的东西就像一个JSON输出，其中显示开始时间和结束时间以及单词和/或句子。

非常感谢您的帮助。

更新所以异步处理程序由于某种原因对我不起作用但是，以下代码确实如此

        While True
            Dim result = recognizer.RecognizeOnceAsync().Result
            Select Case result.Reason
                Case ResultReason.RecognizedSpeech
                    Console.WriteLine($"RECOGNIZED: Text={result.Text}")
                    Console.WriteLine($"    Intent not recognized.")
                Case ResultReason.NoMatch
                    Console.WriteLine($"NOMATCH: Speech could not be recognized.")
                Case ResultReason.Canceled
                    Dim cancellation = CancellationDetails.FromResult(result)
                    Console.WriteLine($"CANCELED: Reason={cancellation.Reason}")

                    If cancellation.Reason = CancellationReason.[Error] Then
                        Console.WriteLine($"CANCELED: ErrorCode={cancellation.ErrorCode}")
                        Console.WriteLine($"CANCELED: ErrorDetails={cancellation.ErrorDetails}")
                        Console.WriteLine($"CANCELED: Did you update the subscription info?")
                    End If

                    Exit While
            End Select
        End While

RecognizeOnceAsync方法将仅识别“一次” ...包含在音频数据文件中的第一个“话语/短语”。如果您想识别多个词组，则可以执行以下两项操作之一：

重复调用RecognizeOnceAsync ...在识别出最后一个短语之后，对该方法的下一次调用将返回将result.Reason设置为Canceled的结果。
从使用RecognizeOnceAsync切换为使用StartContinuousRecognitionAsync，并将事件处理程序挂接到Recognizing事件上。通过事件回调，您可以通过检查传递的SpeechRecognitionEventArgs来查看结果，如下所示：e.Result ...

通过运行语音CLI，您可以看到这两种行为：

spx recognize --once+ --key YOUR-KEY --region YOUR-REGION --file "https://github.com/ullfindsmit/StackOverflowAssets/blob/master/abcdef.wav"
spx recognize --continuous --key YOUR-KEY --region YOUR-REGION --file "https://github.com/ullfindsmit/StackOverflowAssets/blob/master/abcdef.wav"
