ios - 在 Swift 中使用 CocoaPods 时如何实现 Nuance Speechkit

Question

在 pod 规范和目前的 SO 之间，我很难弄清楚如何使用 SpeechKit + CocoaPod + Swift 实现语音到文本的工作。终于让它工作了，所以我想我会帮助下一个寻求帮助的可怜的灵魂！:)

Answer 1

1. 首先安装 CocoaPod：https ://cocoapods.org/pods/SpeechKit
2. 添加#import <SpeechKit/SpeechKit.h>到您的桥接头
3. 登录 Nuance 的开发门户并创建一个应用程序：https ://developer.nuance.com/
4. 清理演示代码，使其更有条理。我只是希望尽可能多的代码在一个地方，这样你就可以看到一个完整的工作实现。

然后创建一个 UIViewController 并使用正确的凭据添加以下代码：

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!) {  }



}
