Wwise 帮助文档

In addition to the speechEngine plug-in library, voices dynamic libraries are required at runtime such as vt_eng.dll or vt_fre.dll for English and French on Windows.

要在构建阶段复制所需的库，请使用 Unity Editor 辅助脚本。该脚本位于 Unity 工程的以下目录中：SDK/Plugins/speechEngine/Unity/Editor/SpeechEnginePluginImporterScript.cs。

Any text you send at runtime must use UTF-8 character encoding. Depending on the platform, you might have to convert text from a different type of encoding to UTF-8. The following code samples for Unity and Unreal demonstrate how to convert UTF-16 encoding (the default on Windows) to UTF-8. You might have to modify the code for other platforms depending on the type of encoding they use.

Unity:

public byte[] ConvertUtf16ToUtf8Bytes(string utf16String)
{
	// Get the UTF-8 encoding
	Encoding utf8 = Encoding.UTF8;

	// Convert the UTF-16 string to a UTF-8 byte array
	byte[] utf8Bytes = utf8.GetBytes(utf16String);

	return utf8Bytes;
}

byte[] textArray = ConvertUtf16ToUtf8Bytes(Text);
System.Runtime.InteropServices.GCHandle pinned = System.Runtime.InteropServices.GCHandle.Alloc(textArray, System.Runtime.InteropServices.GCHandleType.Pinned);
IntPtr address = pinned.AddrOfPinnedObject();
AkUnitySoundEngine.SendPluginCustomGameData(0, this.gameObject, AkPluginType.AkPluginTypeSource, 312, 1, address, (uint)textArray.Length + 1);
pinned.Free();
				

Unreal:

FString utf16_text = TEXT("This is a UTF-16 string at its core.");
FStringView fStringView(utf16_text);
auto ConvertedTemp = StringCast<UTF8CHAR>(fStringView.GetData(), fStringView.Len());
auto utf8_text = ConvertedTemp.Get();
SoundEngine->SendPluginCustomGameData(0, 100, AkPluginTypeSource, 312, 1, utf8_text, ConvertedTemp.Length() + 1);
				

speechEngine 插件不支持 Mac 平台。但若通过 Wwise Unreal/Unity Integration 来生成 SoundBank，将自动为 Mac 生成 SoundBank，而这可能会导致发生错误。因此，建议针对 Mac 以显式方式从工程中弃用所有 speechEngine 元素以避免此类错误。有关详细信息，请参阅从平台中弃用工程元素。

要编译 IntegrationDemo 的 speechEngine 插件页面，您需要修改随 Wwise SDK 一并提供的 Xcode 工程。
