眨眼之間又是好久沒有寫部落格了，佩服那些寫了很多部落格的大神，堅持和耐心值得我學習

這次寫的是一個知名的語音識別sdk，就是科大訊飛的語音識別，其實也沒有多複雜，但是由於我是用swift語言，期間出了很多差錯 ，搞了好久，在這裡就慢慢記錄下來吧。

使用步驟: （有很多步驟網上都已經有了，我大概寫一下主要的步驟，最主要還是把自己遇到的問題說出來，供大家參考）

1、首先是去訊飛官網建立應用，下載SDK，這些都不復雜，百度一大堆
2、下載好之後，把 iflyMSC.framework 拖入到專案中，這地方推薦是把它拷貝到專案資料夾下，然後在工程中add進去。
3、很重要的一個步驟，就是要新增很多相關的庫，如果新增不全，就會報很奇葩的錯誤，而且找不到頭緒，本人就是傻傻的在這裡出了好多錯……
4、新增完檔案之後，由於是swift語言，還要建立一個橋接檔案，然後把SDK的標頭檔案包含進去：

#import "iflyMSC/IFlySpeechRecognizerDelegate.h"
#import "iflyMSC/IFlySpeechRecognizer.h"
#import "iflyMSC/IFlyRecognizerViewDelegate.h"
#import "iflyMSC/IFlyRecognizerView.h"
#import "iflyMSC/IFlyContact.h"
#import "iflyMSC/IFlyUserWords.h"

#import "iflyMSC/IFlyDataUploader.h"

#import "iflyMSC/IFlySpeechSynthesizerDelegate.h"
#import "iflyMSC/IFlySpeechSynthesizer.h"

#import "iflyMSC/IFlySpeechUtility.h"
#import "iflyMSC/IFlySpeechConstant.h"
#import "iflyMSC/IFlySpeechError.h"

#import "iflyMSC/IFlySpeechUnderstander.h"
#import "iflyMSC/IFlyTextUnderstander.h"

#import "iflyMSC/IFlySetting.h"
 

5、做完這些之後，就可以在你的專案中放心使用了，它分為兩種介面，一種是無語音識別介面，一種是有語音識別介面。兩種的使用方法都差不多相同

無介面：

class ViewController: UIViewController,<span style="color:#33cc00;">IFlySpeechRecognizerDelegate</span>,UITextViewDelegate {
    
    
    var iflySpeechRecognizer:<span style="color:#33cc00;">IFlySpeechRecognizer</span>!
    var resultText = ""
    var textView = UITextView()
    var backView:UIView!
    var VoiceTextView:UITextView!
    var voiceView:UIView!
    
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        var initString:String!
        initString = "appid=575fb8bb"
        IFlySpeechUtility.createUtility(initString)
        
        self.iflySpeechRecognizer = IFlySpeechRecognizer.sharedInstance() as IFlySpeechRecognizer
        self.iflySpeechRecognizer.delegate = self
        self.iflySpeechRecognizer.setParameter("iat", forKey: IFlySpeechConstant.IFLY_DOMAIN())
        self.iflySpeechRecognizer.setParameter("16000", forKey: IFlySpeechConstant.SAMPLE_RATE())
        self.iflySpeechRecognizer.setParameter("plain", forKey: IFlySpeechConstant.RESULT_TYPE())
        self.iflySpeechRecognizer.setParameter("-1", forKey: IFlySpeechConstant.SPEECH_TIMEOUT())
        self.iflySpeechRecognizer.setParameter("8000", forKey: IFlySpeechConstant.VAD_EOS())
        self.iflySpeechRecognizer.setParameter("8000", forKey: IFlySpeechConstant.VAD_BOS())
        self.iflySpeechRecognizer.setParameter("500000", forKey: IFlySpeechConstant.SPEECH_TIMEOUT())
        self.iflySpeechRecognizer.setParameter("50000", forKey: IFlySpeechConstant.NET_TIMEOUT())
        
        
        textView.frame = CGRectMake(50, 200, 200, 100)
        textView.textColor = UIColor.whiteColor()
        textView.text = "lllllll"
        self.view.addSubview(textView)
        
        let btn:UIButton = UIButton(frame:CGRectMake(100,100,100,100))
        btn.backgroundColor = UIColor.redColor()
        btn.setTitle("語音識別", forState: UIControlState.Normal)
        btn.addTarget(self, action: #selector(startVoiceBtn), forControlEvents: UIControlEvents.TouchUpInside)
        self.view.addSubview(btn)
    }

其實沒有多少注意的地方，就是遵循那個代理，然後實現兩個代理方法就行了，真機測試之後就會發現，在onReaults中就能打印出識別的文字了，然後根據自己的需求不同來對字串進行處理，這裡特別注意的是聯網，真機測試，然後用普通話說出想要識別的文字，如果光發出聲響，他就會一直報識別錯誤的錯。

有介面:

import UIKit

class voiceViewController: UIViewController,IFlyRecognizerViewDelegate {

    var iflyRecognizerView:IFlyRecognizerView!
    
    var isRecongnizer = false
    var resultText = ""
    var textView = UITextView()
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        
        var initString:String!
        initString = "appid=575fb8bb"
        IFlySpeechUtility.createUtility(initString)
        
        self.iflyRecognizerView = IFlyRecognizerView.init(center: self.view.center)as IFlyRecognizerView
        self.iflyRecognizerView.delegate = self
        self.iflyRecognizerView.setParameter("iat", forKey: IFlySpeechConstant.IFLY_DOMAIN())
        self.iflyRecognizerView.setParameter("16000", forKey: IFlySpeechConstant.SAMPLE_RATE())
        // | result_type   | 返回結果的資料格式 plain,只支援plain
        self.iflyRecognizerView.setParameter("plain", forKey: IFlySpeechConstant.RESULT_TYPE())
        
        
        textView.frame = CGRectMake(50, 200, 200, 100)
        textView.backgroundColor = UIColor.grayColor()
        textView.textColor = UIColor.whiteColor()
        textView.text = "lllllll"
        self.view.addSubview(textView)
        
        let btn:UIButton = UIButton(frame:CGRectMake(100,100,100,100))
        btn.backgroundColor = UIColor.redColor()
        btn.setTitle("語音識別", forState: UIControlState.Normal)
        btn.addTarget(self, action: #selector(startVoiceBtn), forControlEvents: UIControlEvents.TouchUpInside)
        self.view.addSubview(btn)

    }
    
    func startVoiceBtn() {
        print("開始識別")
        iflyRecognizerView.start()
        
    }
    
    func onResult(results: [AnyObject]!,isLast: Bool) {
        var resultStr : String = ""
        if results != nil {
            let resultDic : Dictionary<String, String> = results[0] as! Dictionary<String, String>
            
            for key in resultDic.keys {
                resultStr += key
            }
        }
        
        if resultText != "" {
            if (resultText as NSString).substringWithRange(NSMakeRange( resultText.characters.count - 1, 1)) != "," {
                resultText += ","
            }
        }
        
        resultText += resultStr
        textView.text = resultText
        
        if isRecongnizer {
            iflyRecognizerView.start()
        } else {
            iflyRecognizerView.cancel()
            if resultText != "" {
                resultText = (resultText as NSString).substringWithRange(NSMakeRange( 0, resultText.characters.count - 1)) + "。"
                textView.text = resultText
            }
        }
    }
    
    func onError(error: IFlySpeechError!) {
        print("識別出錯：\(error.errorCode)")
    }
    

6、兩種方法就是遵循的代理不同，然後用到的類不同，其實也沒有多複雜的地方，只是剛開始的時候有點蒙，用起來就好了
