Remarks
An SFSpeechRecognizer asynchronously processes SFSpeechRecognitionRequest objects, generating SFSpeechRecognitionResult objects.
Apps that use speech recognition must add the following key, with appropriate descriptions, in their info.plist file:
<key>NSSpeechRecognitionUsageDescription</key>
<string>Speech recognition will be used to determine which words you speak into this device's microphone.</string>
If an application does not have this key, the operating system will execute a "silent" shutdown at runtime, with no exception or ability to log the mistake.
Additionally, if the app uses the AVAudioEngine to access the microphone, the app must also contain a <key>NSMicrophoneUsageDescription</key> key.
