I'm looking for a RESTful Speech to Text service for iOS that will allow me to attach an audio file to a POST request (with an API like AFNetworking), then receive a text response of the translated text. The AT&T API for Speech to Text seems interesting, but there doesn't seem to be any documentation about working with Objective-C.
Are there any such services, free/paid, that would offer the ability to "translate" an audio file into text through a POST request?
How about using the Nexiwave API? I've heard some pretty great stuff about it. http://nexiwave.com/index.php/site-map/119-integrate-voicemail-to-text-in-5-minutes
