You can customize the announce message anyway you want. Create your own message with variables which will be replaced in real-time with the notification title, subtitle, message or app name which caused the notification.
Choose from many speak conditions including:
- Bluetooth only
- Earphones only
- At specific time
- Per app specific
You can also configure the speak behavior, like disabling the notification sound when the speak is enabled or the possibility to stop the speaking with the power button.
If you are listening to music then the music will automatically pause when the announce starts and resumes after the announce ends.
Speak Notification will work any iOS 7 device. It doesn't require Siri but it does require banner notifications be enabled for any app you want to use it with. Configuration is performed from the Settings.app.
You can purchase Speak Notification from the Cydia Store for $1.49.
