9在Swift上实现Nuance语音识别，无法监听onResult、onError...事件 [英] 9Implementing Nuance Speech Recognition on Swift, cannot listen to onResult, onError... events

问题描述

我的 Speech Recon 项目有两部分与 Nuance，模块的 .h 文件 (ObjectiveC) 和 ViewController (swift).

I have two parts of my Speech Recon project with Nuance, the .h file of a module (ObjectiveC) and aViewController (swift).

我想在我的swiftviewController中设置一个SpeechRecognition对象，并监听onBegin、onStop...等方法.

I want to set up aSpeechRecognition object in my swiftviewController, and listen to onBegin, onStop... and such methods.

使其编译的唯一方法是使用 nil 作为委托参数来初始化 SpeechRecon 对象.显然这不好，因为我的 onStart... 和 onFinish 函数不会触发.

The only way to make it compile is to use nil as the delegate parameter to initialize the SpeechRecon object. Obviously this is not good because my onStart... and onFinish functions don´t trigger.

我已经为 SKRecogniser 文件实现了一个协议，并将我的 ViewController 类扩展到 SKReconDelegate...但是如果我使用self"作为委托来初始化对象，编译器会说UIViewController 不是一个有效的类.我知道我需要在两个类之间建立一些委托，但我是一名 android 开发人员，我的 iOS 技能仍然不够敏锐.这是代码，如果我错过了一些重要的部分，请告诉我.我将非常感谢您的帮助.

I have implemented a protocol to theSKRecogniser file, and extended my ViewController class to SKReconDelegate... but if I use "self" as a delegate to initialize object, the compiler will say thatUIViewController is not a valid class. I know I need to establish some delegate between both classes, but I am an android developers, and my iOS skills are still not sharp enough. Here is the code, if I missed some important piece just let me know. I will be very thankful for your help.

//ViewController code, in SWIFT
//NO PROTOCOLS NEEDED HERE!

class ViewController:  UIViewController, SpeechKitDelegate, SKRecognizerDelegate{

override func viewDidLoad() {
        super.viewDidLoad()
        SpeechKit.setupWithID( "NMDPTRIAL_nuance_chch_com9999",
            host:"sandbox.nmdp.nuancemility.net",
            port:443,
            useSSL:false,
            delegate:self) //error said "self" is of an invalid ViewController type :( because I was NOT implementing all 4 methods BELOW:
   }
//a bit ahead, I have the same problem with a button
@IBAction func btnmicaction(sender: AnyObject) {
   self.voiceSearch=SKRecognizer(type: "websearch", detection: 2, language: langType as String, delegate: self) //error said "self" is of an invalid ViewController type :( because I was NOT implementing all 4 methods BELOW:
   }


//IMPLEMENT ALL THESE 4 FUNCTIONS, AS SUGGESTED BY THE SOLUTION
func recognizerDidBeginRecording(recognizer:SKRecognizer){
        println("************** ReconBeganRecording")
        }

func recognizerDidFinishRecording(recognizer:SKRecognizer){
        println("************** ReconFinishedRecording")
        }

func recognizer(recognizer: SKRecognizer!, didFinishWithResults results: SKRecognition!){
    //The voice recognition process has understood something
    }

func recognizer(recognizer: SKRecognizer!, didFinishWithError error: NSError!, suggestion: String!){
   //an error has occurred
   }
}

以防万一，这是我的桥头:

Just in case, here is my Bridge header:

#ifndef Vanilla_Bridge_h
#define Vanilla_Bridge_h
#import <SpeechKit/SpeechKit.h>

更新请参阅下面的解决方案！

UPDATE SEE SOLUTION BELOW!!

推荐答案

这就是我得到的桥接头:

Here's what I've got Bridging Header:

#import <SpeechKit/SpeechKit.h>
#import "NuanceHeader.h"

NuanceHeader.h:

NuanceHeader.h:

#import <Foundation/Foundation.h>
@interface NuanceHeader : NSObject
@end

NuanceHeader.m

NuanceHeader.m

#import "NuanceHeader.h"
const unsigned char SpeechKitApplicationKey[] = {...};
@implementation NuanceHeader
@end

说到使用这一切的 UIViewController:

When it comes to the UIViewController that uses all this:

class MyViewController: UIViewController, SpeechKitDelegate, SKRecognizerDelegate
{
    var voiceSearch: SKRecognizer?

    override func viewDidLoad()
    {
       //Setup SpeechKit
       SpeechKit.setupWithID("...", host: "sandbox.nmdp.nuancemobility.net", port: 443, useSSL: false, delegate: self)
    }

    func someAction()
    {
        self.voiceSearch = SKRecognizer(type: SKSearchRecognizerType, detection: UInt(SKLongEndOfSpeechDetection), language:"eng-USA", delegate: self)

    }

    func recognizerDidBeginRecording(recognizer: SKRecognizer!)
    {
        //The recording has started
    }

    func recognizerDidFinishRecording(recognizer: SKRecognizer!)
    {
        //The recording has stopped
    }

    func recognizer(recognizer: SKRecognizer!, didFinishWithResults results: SKRecognition!)
    {
        //The voice recognition process has understood something
    }

    func recognizer(recognizer: SKRecognizer!, didFinishWithError error: NSError!, suggestion: String!)
    {
       //an error has occurred
    }
}

没有别的了，检查每一步，这部分很简单

There is nothing else to it, check every step, this part is pretty straight forward
