使用语音识别播放随机wav文件 [英] play random wav file using voice recognition

问题描述

我拥有所需的所有语音项目，因为项目将使用语音命令运行并以应有的方式响应。这是代码的一小部分。当我把它分配给表格上的一个按钮时，它会播放一个ramdom wav，它们最多只有10秒钟。我想移动到当我说其中一个关键词时它会像按下按钮时一样响应。我想我需要一行代码，但无法理解。





我正在处理语音请求程序当我说一个关键词时，我正试图让它播放一个随机的.wav文件。这是我到目前为止所做的，如果你按下表格上的一个按钮，它确实有效但我希望它在听到其中一个单词时播放。但无法获得最后的平安，任何帮助都会很棒。还在学习：

  case    for：
  case    help：
  case    now：
  string  [] files = Directory.GetFiles（ @  C：\ Users\chuck\voice< /跨度>）; 
 Random rnd =  new  Random（Guid.NewGuid（）。GetHashCode（））; 
  int  choice = rnd.Next（ 0 ，files.Length  -   1 ）; 
  string  soundFile = files [choice]; 
 System.Media.SoundPlayer player =  new  System.Media.SoundPlayer（soundFile）; 
 player.Play（）; 

我在C＃

解决方案

您可以使用 System.Speech.Recognition ：

http://msdn.microsoft.com/en-us/library/system .speech.recognition％28v = vs.110％29.aspx [ ^ ]。



替代方案是： SpeechRecognizer 或 SpeechRecognitionEngine ：

http://msdn.microsoft.com/en-us/library/system.speech.recognition.speechrecognizer（v = VS。 110）.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.speech.recognition.speechrecognitionengine(v = vs.110）.aspx [ ^ ] 。



第一个请求STA线程公寓状态，第二个请求MTA。因此，如果您使用需要STA的WPF，您可以在单独的MTA线程中使用 SpeechRecognitionEngine ;和其他应用程序类型可以使用主线程中的任何公寓状态。这是通常的困难，因为微软没有正确记录这种微妙之处;其他一切或多或少都是直截了当的。而且，对于大语法集的识别质量是非常值得怀疑的，但只需要一些命令就足以让它变得可行。

i have all speech items needed as the project will run with voice commands and respond the way it should. this is a small piece of the code. when i had this assigned to a button on the form it would play one ramdom wav, they are only about 10 seconds long at the most. i want to move to when i say one of the key words it will respond the same as when you push the button. i think i need one line of code but can't figure it out.


I'm working on a speech req program and I'm trying to get it to play a random .wav file when i say a key word. this is what i have so far and it does work if you push a button on the form but i want it to play when it hears one of the words spoken. but can't get the last peace, any help would be great. still learning:

case "for":
case "help":
case"now":
    string[] files = Directory.GetFiles(@"C:\Users\chuck\voice");
    Random rnd = new Random(Guid.NewGuid().GetHashCode());
    int choice = rnd.Next(0, files.Length - 1);
    string soundFile = files[choice];
    System.Media.SoundPlayer player = new System.Media.SoundPlayer(soundFile);
    player.Play();

I'm doing this in C#

解决方案

You can use System.Speech.Recognition:
http://msdn.microsoft.com/en-us/library/system.speech.recognition%28v=vs.110%29.aspx[^].

The alternatives are: SpeechRecognizer or SpeechRecognitionEngine:
http://msdn.microsoft.com/en-us/library/system.speech.recognition.speechrecognizer(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.speech.recognition.speechrecognitionengine(v=vs.110).aspx[^].

First one requites STA thread apartment state, and second one MTA. So, if you use WPF which requires STA, you can work SpeechRecognitionEngine in a separate thread set to MTA; and other application types could use any apartment state in the main threads. This is the usual difficulty, because this subtlety is not documented by Microsoft properly; everything else is more or less straightforward. And, well… quality of recognition of big grammar sets is quite questionable, but with just a set of few commands it's good enough to make it doable.
