If you use Apple's EarPods, or certain other headphones with an inline remote control for listening to your music, then you can probably benefit from a new jailbreak tweak called Headphone Assistant by iOS developer Jea.
Headphone Assistant will make it so that you can use some of the controls on your inline remote to perform additional functions. For example, telling the current time, reading your notifications, and even telling the caller name from phone calls or FaceTime calls. Everything can be done while the device is locked in your pocket.
The tweak adds a preferences pane to your Settings application where you can enable or disable the tweak on demand. Also, the settings are divided into four sections: Voice, Current Time, Notification, and Caller Name.
From the Voice section, you can choose the language of the voice that is used to speak to you, configure the pitch of the voice, the rate of the voice, and the post delay of the voice. There is even a "Test Speak" button included in here so that you can test out the voice each time you make changes to the settings.
From the Current Time section, you can enable or disable this feature, choose to use the feature only when the Lock Screen is dimmed (or when the Lock Screen is undimmed too), choose to use the feature while reading notifications, and configure the time format that you would like to have read to you.
From the Notification section, you can enable or disable this feature, choose to use the feature only when the Lock Screen is undimmed (or when the Lock Screen is dimmed too), choose whether the feature will repeat notifications more than once, choose the maximum number of read counts, and configure a format that you would like to have your notifications read to you in.
And finally, from the Caller Name section, you can enable or disable this feature, choose to use the feature only in headphone mode, and configure the repeat count.
Headphone Assistant works best with Apple-branded EarPods, but will work will some third-party headphones as well. We tested with Apple's EarPods, as well as some JVC headphones that we bought from Walmart.
If you'd like to give Headphone Assistant a try, it's available in Cydia's BigBoss repository right now for $1.99. Both iOS 6 and iOS 7 are supported.
iOS 6.0-7.0.6, headphones with inline remote
iPhone 5 running iOS 7.0.6 with Apple EarPods
