Apple released today the fifth beta of iOS 7.1 to registered developers, and it’s available via OTA ( over-the-air ) or through Apple’s developer center website. The new updated brings new natural-sounding Siri voices for English (Australia), English (United Kingdom), Japanese, and Chinese (Mandarin – China). The releases notes mention that a compact version of Siri is bundled with the release for the new languages but after you have configured a WiFi network and have the device connected to a power source, iOS will automatically download and install a higher quality version. iOS 7.1 beta 5 also includes a redesigned shift and caps lock keys.
NOTE: Jailbreakers stay away from this update
