This sample app includes source code and an Xcode project to show how to call the AT&T Speech SDK from an application. The app displays a simple client-side mashup. Pressing a button initiates a speech interaction, a text area shows the recognition result, and a web view uses the recognized speech to search a website.
Done
Done for configuration for your Speech API account: the URL of the service, your application's API key and API secret. Set those values in SpeechConfig.m. Before distributing your app to the public, make sure you add code to obfuscate those credentials.
The main code of the sample app is in the SimpleSpeechViewController class. Look in the -[prepareSpeech] and -[listen:] methods for examples of setting up and starting a speech interaction. Look in the -[speechServiceSucceeded:] and [speechService:failedWithError:] methods for examples of handling recognition responses.
The SpeechAuth class provides example code for authenticating your application with the OAuth client credentials protocol. It performs an asynchronous network request for an OAuth access token that can be used in the Speech API. Look in -[SimpleSpeechViewController prepareSpeech] for examples of calling SpeechAuth to obtain an access token.
