注解
与涉及隐私的其他因素一样，用户必须积极允许应用访问语音识别。
使用语音识别的应用必须在其 info.plist 文件中添加以下密钥以及相应的说明：
<key>NSSpeechRecognitionUsageDescription</key>
<string>Speech recognition will be used to determine which words you speak into this device's microphone.</string>
如果应用程序没有此密钥，操作系统将在运行时执行“无提示”关闭，没有异常或记录错误的能力。
字符串的值 info.plist 将呈现给用户以响应 RequestAuthorization(Action<SFSpeechRecognizerAuthorizationStatus>) 方法：
if (SFSpeechRecognizer.AuthorizationStatus != SFSpeechRecognizerAuthorizationStatus.Authorized)
{
SFSpeechRecognizer.RequestAuthorization((status) =>
{
switch (status)
{
case SFSpeechRecognizerAuthorizationStatus.Authorized:
InvokeOnMainThread(() => prepareButton.Enabled = true);
break;
case SFSpeechRecognizerAuthorizationStatus.Restricted:
case SFSpeechRecognizerAuthorizationStatus.NotDetermined:
case SFSpeechRecognizerAuthorizationStatus.Denied:
InvokeOnMainThread(() => prepareButton.Enabled = false);
break;
}
});
}
