How to implement Nuance Speechkit when using CocoaPods in Swift - ios

Question

Between the pod spec and what is currently on S.O. I had a tough time figuring out how to get speech-to-text working using SpeechKit + CocoaPod + Swift. Finally got it working so figured I'd help the next poor soul that comes looking for help! :)

Answer 1

First install the CocoaPod: https://cocoapods.org/pods/SpeechKit
Add #import <SpeechKit/SpeechKit.h> to your bridging header
Login to Nuance's dev portal and create an app: https://developer.nuance.com/
Clean up the demo code so that is is more organized. I just wanted as much of the code to be in one place as possible so you can see a fully working implementation.
Then create a UIViewController and add the following code with the correct credentials:
import UIKit
import SpeechKit
class SpeechKitDemo: UIViewController, SKTransactionDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//!!link this to a corresponding button on the UIViewController in I.B.
#IBAction func tappedButton(sender: AnyObject) {
// All fields are required.
// Your credentials can be found in your Nuance Developers portal, under "Manage My Apps".
let SKSAppKey = "[Get this from the nuance app info page]";
let SKSAppId = "[Get this from the nuance app info page]";
let SKSServerHost = "[Get this from the nuance app info page]";
let SKSServerPort = "[Get this from the nuance app info page]";
let SKSLanguage = "eng-USA";
let SKSServerUrl = "nmsps://\(SKSAppId)#\(SKSServerHost):\(SKSServerPort)"
let session = SKSession(URL: NSURL(string: SKSServerUrl), appToken: SKSAppKey)
//this starts a transaction that listens for voice input
let transaction = session.recognizeWithType(SKTransactionSpeechTypeDictation,
detection: .Short,
language: SKSLanguage,
delegate: self)
print(transaction)
}
//required delegate methods
func transactionDidBeginRecording(transaction: SKTransaction!) { }
func transactionDidFinishRecording(transaction: SKTransaction!) { }
func transaction(transaction: SKTransaction!, didReceiveRecognition recognition: SKRecognition!) {
//Take the best result
let topRecognitionText = recognition.text;
print("Best rec test: \(topRecognitionText)")
//Or iterate through the NBest list
let nBest = recognition.details;
for phrase in (nBest as! [SKRecognizedPhrase]!) {
let text = phrase.text;
let confidence = phrase.confidence;
print("\(confidence): \(text)")
}
}
func transaction(transaction: SKTransaction!, didReceiveServiceResponse response: [NSObject : AnyObject]!) { }
func transaction(transaction: SKTransaction!, didFinishWithSuggestion suggestion: String!) { }
func transaction(transaction: SKTransaction!, didFailWithError error: NSError!, suggestion: String!) { }
}
