如何在Unity项目中添加语音识别?

问题描述

我目前正在使用Vuforia进行增强现实项目，该项目使用语音识别来控制Unity中的对象.我只是在寻找示例工作代码.

I am presently working on a Augmented Reality project using Vuforia that uses Speech recognition to control the objects in Unity. I was just looking for a sample working code.

推荐答案

Unity尚未内置此功能.他们已经对它进行研究很长时间了，这很可能会很快就会加入Unity.您可以从Assets商店此处获取有效的语音转文本(免费) .它是开源的，如果发现任何问题，您可以做出贡献.

Unity does not have this built in yet. They have been doing research on it for a long time and this will likely be added into Unity very soon. You can get the working Speech-to-Text(free) from the Assets store here. It is open source and you can help contribute to it if you find any problems.

请注意，几乎每个操作系统都具有语音识别API.通过将所有这些API包装到C#中的sing类中，然后使用 Unity的平台预处理程序指令确定要调用哪个操作系统，具体取决于您的游戏运行的操作系统.

As a side note, almost every OS has a Speech Recognition API. You easily make a plugin by wrapping all those API into a sing class in C# then use Unity's platform preprocessor directives to determine which one to call depending on which OS your game is running on.

Android :

SpeechRecognizer 类.

查看此项目 https://github.com/gsssrao/UnityAndroidSpeechRecognition

iOS :

SFSpeechRecognizer 类

MacOS :

NSSpeechRecognizer 类

Windows :

SpeechRecognitionEngine 类

查看此项目 https://github.com/LightBuzz/Speech-Recognition-Unity

示例:

class CrazySpeechRecognition
{
  #if UNITY_ANDROID
    Use SpeechRecognizer class
  #endif

  #if UNITY_IOS
    Use SFSpeechRecognizer class
  #endif

  #if UNITY_STANDALONE_OSX || UNITY_EDITOR_OSX
    Use NSSpeechRecognizer class
  #endif

  #if UNITY_STANDALONE_WIN || UNITY_EDITOR_WIN
    Use SpeechRecognitionEngine class
  #endif
}

来自Unity的免费语音转换令人遗憾如链接中所述已停产.

The free Speech-to-Text from Unity is sadly discontinued, as stated in the link.
