关于在dotnet下，语音唤醒词kws的问题

[seredipitypsy]

@pkufool 简单描述一下。我直接用的keyword-spotting-from-microphone这个demo 但是添加唤醒词 比如输入 带有“XX室” 或者“XX础" （目前只测出这两个字有问题） 的时候会报错 初始化的时候就错误了
代码如下： public class keyword_spotting_from_microphone
{
public keyword_spotting_from_microphone()
{
var config = new KeywordSpotterConfig();
config.FeatConfig.SampleRate = 16000;
config.FeatConfig.FeatureDim = 80;
config.ModelConfig.Transducer.Encoder = "./sherpa-onnx-kws-zipformer-wenetspeech-3.3M-2024-01-01/encoder-epoch-12-avg-2-chunk-16-left-64.onnx";
config.ModelConfig.Transducer.Decoder = "./sherpa-onnx-kws-zipformer-wenetspeech-3.3M-2024-01-01/decoder-epoch-12-avg-2-chunk-16-left-64.onnx";
config.ModelConfig.Transducer.Joiner = "./sherpa-onnx-kws-zipformer-wenetspeech-3.3M-2024-01-01/joiner-epoch-12-avg-2-chunk-16-left-64.onnx";
config.ModelConfig.Tokens = "./sherpa-onnx-kws-zipformer-wenetspeech-3.3M-2024-01-01/tokens.txt";
config.ModelConfig.Provider = "cpu";
config.ModelConfig.NumThreads = 1;
config.ModelConfig.Debug = 1;
config.KeywordsFile = "./sherpa-onnx-kws-zipformer-wenetspeech-3.3M-2024-01-01/test_wavs/test_keywords.txt";
var kws = new KeywordSpotter(config);
Console.WriteLine("----------Use pre-defined keywords----------");
OnlineStream kws_s = kws.CreateStream("j ī x iè s hì @机械室"); //报错
Console.WriteLine(PortAudio.VersionInfo.versionText);
PortAudio.Initialize();

报错位置 stream.Start();
while (true)
{
while (kws.IsReady(kws_s)) //报错位置
{
kws.Decode(kws_s);
}

   var result = kws.GetResult(kws_s);
   if (result.Keyword != "")
   {
       Console.WriteLine("关键词已识别: {0}", result.Keyword);
   }

   Thread.Sleep(200); // ms
