Apps wrapped with AppConnect 4.0 for iOS block the use of dictation when using the native iOS keyboard. You can override this behavior by setting a key-value pair on the app’s configuration. The key is called MI_AC_WR_ALLOW_KEYBOARD_DICTATION. If you do not include the key, dictation is not allowed. If you set the value to true, then wrapped AppConnect apps can use dictation with the native keyboard.
Apps built with the AppConnect for iOS SDK, and apps wrapped with wrapper versions prior to AppConnect 4.0 for iOS allow the use of dictation when using the native iOS keyboard. The key MI_AC_WR_ALLOW_KEYBOARD_DICTATION has no impact on those apps.
