Have some of this in Sprint specs we can look up. The items on screen are read out. Mostly for accessibly but can be used by sighted users, and i f good, coin be very useful. Think about GPS directions, and how much its become a joke. Make it better! Alison's phone announces (badly!) callers with a text-to-voice. Use that as a good sample where it sorta crosses with reminders (it's a notification, with privacy etc. issues) as well as on onscreen readout, but also as an anti-pattern since it launches into it, and is un-understandable).

Basically, TTS (text to speech)

Fair bit about it being the output side of voice input, so together it's a voice control system

Problem

Solution

Mobile devices must be able to read text displayed on the screen, so it can be accessed and understood by users who cannot use the screen, for any reason.

Variations

Universal - whole interface, output side (replacing the screen) for a complete voice I/O.

Elemental - Read a document, a web page, etc. Then ends.

Selected - Read a selection

Confirmation - In a voice I/O, reads back entry to confirm that this is what is intended.

Voice output that is presented based on conditions, such as position or time, are discussed under the Voice Reminders pattern.

Interaction Details

Presentation Details

Content read must be identical to that printed on the screen. The condition that resulted in user employing Voice Readback may be temporary and transient; the user may switch between the screen and audio channels, or may even read along with the voice output. Even for users with a vision deficit, others may be accompanying them, who may also wish to use the device.
