Type and Talk

You mean you want the iphone to speak the time?

If so your out of luck unless you record somebody saying every single possible minute and hour.

 

On a Mac yes, on an iPhone no (at least at a level you can use in your own code).

 

This has been answered above: there is no speech synthesiser you can use on the iPhone. You can choose to record voice samples for all the words/phrases you need and play them yourself as required.

 

I know on a mac you could use the terminal command. But for iPhone you might have to record it on a computer and play it back on an iPhone.

 

There currently is no public speech synthesizer API in the iPhone OS. Whether or not you can use the existing private speech synthesizer API built into the iPhone depends on whether you want an app to be approved for App store distribution or not. (e.g. is your app for personal use?)

There are also at least a couple 3rd party speech synthesizer libraries that you could include with your app. These may or may not be expensive to license.

 

You might have luck with this open source library (released under the MIT license) that I found after scouring the web.
