c# - 如何从文件中进行语音识别，System.ApplicationException 0xa SPXERR_INVALID_HEADER

Question

我正在尝试对这样的 wav 文件进行语音识别:

var config = SpeechConfig.FromSubscription("mykey", "myregion");

using (var recognizer = new SpeechRecognizer(config, AudioConfig.FromWavFileInput(@"/Full/Path/To/File.wav")))
{
    recognizer.Recognized += (s, e) =>
    {
        if (e.Result.Reason == ResultReason.RecognizedSpeech)
        {
            Console.WriteLine(e.Result.Text);
        }
    };

    await recognizer.StartContinuousRecognitionAsync();
}

但我收到此错误:

Unhandled Exception: System.AggregateException: One or more errors occurred. (Exception with an error code: 0xa (SPXERR_INVALID_HEADER)) ---> System.ApplicationException: Exception with an error code: 0xa (SPXERR_INVALID_HEADER)

第 14 行是

using (var recognizer = new SpeechRecognizer(config, AudioConfig.FromWavFileInput(@"/Full/Path/To/File.wav")))

行

我实际上如何在文件上使用语音服务？我让它在现场麦克风输入上工作。

我刚刚再次尝试使用不同格式的文件(WAV 文件、16 kHz 采样率、单声道)，现在出现此错误:

libc++abi.dylib: terminating with uncaught exception of type
Microsoft::CognitiveServices::Speech::Impl::ExceptionWithCallStack: Exception with
an error code: 0xd (SPXERR_ABORT)

Answer 1

正如您所说 - 它似乎正在使用标准 WAV 文件......

I downloaded a wav file for the Internet and I was able to make it work with

您自制的 WAV 文件似乎不符合预期的 WAV 格式规范(WAV/PCM 16 位、16 kHz/8 kHz、单声道音频)？
