将Microsoft Project Oxford语音识别从Objective-C转换为SWIFT

Microsoft Project Oxford在iOS上有一个很好的语音识别API和Objective-C指令。 按照入门指导，我可以轻松构build它。 但是，我很难将其转换为Swift语言。

我首先创build了一个快速项目。 我创build了桥头文件（ProjectName-Bridging-Header.h）并将以下代码插入到此文件中： 

#import "SpeechRecognitionService.h"

我想将Objective-C的头文件和实现文件转换成ViewController.swift。

ViewController.h的内容： 

 #import <UIKit/UIKit.h> #import "SpeechRecognitionService.h" @interface ViewController : UIViewController<SpeechRecognitionProtocol> { NSMutableString* textOnScreen; DataRecognitionClient* dataClient; MicrophoneRecognitionClient* micClient; SpeechRecognitionMode recoMode; bool isMicrophoneReco; bool isIntent; int waitSeconds; } @property (nonatomic, strong) IBOutlet UIButton* startButton; /* In our UI, we have a text box to show the reco results.*/ @property (nonatomic, strong) IBOutlet UITextView* quoteText; /* Action for pressing the "Start" button */ -(IBAction)startButtonTapped:(id)sender; @end

ViewController.m的内容： 

 #import "ViewController.h" #import <AVFoundation/AVAudioSession.h> @interface ViewController (/*private*/) /* Create a recognition request to interact with the Speech Service.*/ -(void)initializeRecoClient; @end NSString* ConvertSpeechRecoConfidenceEnumToString(Confidence confidence); /* The Main App */ @implementation ViewController /* Initialization to be done when app starts. */ -(void)viewDidLoad { [super viewDidLoad]; textOnScreen = [NSMutableString stringWithCapacity: 1000]; recoMode = SpeechRecognitionMode_ShortPhrase; isMicrophoneReco = true; isIntent = false; waitSeconds = recoMode == SpeechRecognitionMode_ShortPhrase ? 20 : 200; [self initializeRecoClient]; } /* Called when a partial response is received. */ -(void)onPartialResponseReceived:(NSString*) response { dispatch_async(dispatch_get_main_queue(), ^{ [textOnScreen appendFormat:(@"%@\n"), response]; self.quoteText.text = response; }); } /* Called when a final response is received. */ -(void)onFinalResponseReceived:(RecognitionResult*)response { bool isFinalDicationMessage = recoMode == SpeechRecognitionMode_LongDictation && (response.RecognitionStatus == RecognitionStatus_EndOfDictation || response.RecognitionStatus == RecognitionStatus_DictationEndSilenceTimeout); if (isMicrophoneReco && ((recoMode == SpeechRecognitionMode_ShortPhrase) || isFinalDicationMessage)) { [micClient endMicAndRecognition]; } if ((recoMode == SpeechRecognitionMode_ShortPhrase) || isFinalDicationMessage) { dispatch_async(dispatch_get_main_queue(), ^{ [[self startButton] setEnabled:YES]; }); } } NSString* ConvertSpeechErrorToString(int errorCode) { switch ((SpeechClientStatus)errorCode) { case SpeechClientStatus_SecurityFailed: return @"SpeechClientStatus_SecurityFailed"; case SpeechClientStatus_LoginFailed: return @"SpeechClientStatus_LoginFailed"; case SpeechClientStatus_Timeout: return @"SpeechClientStatus_Timeout"; case SpeechClientStatus_ConnectionFailed: return @"SpeechClientStatus_ConnectionFailed"; case SpeechClientStatus_NameNotFound: return @"SpeechClientStatus_NameNotFound";

case SpeechClientStatus_InvalidArgument: return @"SpeechClientStatus_InvalidArgument"; } return [[NSString alloc] initWithFormat:@"Unknown error: %d\n", errorCode]; } /* Called when an error is received. */ -(void)onError:(NSString*)errorMessage withErrorCode:(int)errorCode { dispatch_async(dispatch_get_main_queue(), ^{ [[self startButton] setEnabled:YES]; [textOnScreen appendString:(@"********* Error Detected *********\n")]; [textOnScreen appendFormat:(@"%@ %@\n"), errorMessage, ConvertSpeechErrorToString(errorCode)]; self.quoteText.text = textOnScreen; }); } /* Event fired when the microphone recording status has changed. */ -(void)onMicrophoneStatus:(Boolean)recording { if (!recording) { [micClient endMicAndRecognition]; } dispatch_async(dispatch_get_main_queue(), ^{ if (!recording) { [[self startButton] setEnabled:YES]; } self.quoteText.text = textOnScreen; }); } /* Create a recognition request to interact with the Speech Recognition Service.*/ -(void)initializeRecoClient { NSString* language = @"en-us"; NSString* path = [[NSBundle mainBundle] pathForResource:@"settings" ofType:@"plist"]; NSDictionary* settings = [[NSDictionary alloc] initWithContentsOfFile:path]; NSString* primaryOrSecondaryKey = [settings objectForKey:(@"primaryKey")]; NSString* luisAppID = [settings objectForKey:(@"luisAppID")]; NSString* luisSubscriptionID = [settings objectForKey:(@"luisSubscriptionID")]; if (isMicrophoneReco) { if (!isIntent) { micClient = [SpeechRecognitionServiceFactory createMicrophoneClient:(recoMode) withLanguage:(language) withKey:(primaryOrSecondaryKey) withProtocol:(self)]; } else { MicrophoneRecognitionClientWithIntent* micIntentClient; micIntentClient = [SpeechRecognitionServiceFactory createMicrophoneClientWithIntent:(language) withKey:(primaryOrSecondaryKey) withLUISAppID:(luisAppID) withLUISSecret:(luisSubscriptionID) withProtocol:(self)]; micClient = micIntentClient; } } else { if (!isIntent) { dataClient = [SpeechRecognitionServiceFactory createDataClient:(recoMode) withLanguage:(language) withKey:(primaryOrSecondaryKey) withProtocol:(self)]; } else { DataRecognitionClientWithIntent* dataIntentClient; dataIntentClient = [SpeechRecognitionServiceFactory createDataClientWithIntent:(language) withKey:(primaryOrSecondaryKey) withLUISAppID:(luisAppID) withLUISSecret:(luisSubscriptionID) withProtocol:(self)]; dataClient = dataIntentClient; } } } /* Take enum value and produce NSString */ NSString* ConvertSpeechRecoConfidenceEnumToString(Confidence confidence) { switch (confidence) { case SpeechRecoConfidence_None: return @"None"; case SpeechRecoConfidence_Low: return @"Low"; case SpeechRecoConfidence_Normal: return @"Normal"; case SpeechRecoConfidence_High: return @"High"; } } /* Action for pressing the "Start" button */ -(IBAction)startButtonTapped:(id)sender { [textOnScreen setString:(@"")]; self.quoteText.text = textOnScreen; [[self startButton] setEnabled:NO]; if (isMicrophoneReco) { OSStatus status = [micClient startMicAndRecognition]; if (status) { [textOnScreen appendFormat:(@"Error starting audio. %@\n"), ConvertSpeechErrorToString(status)]; } } } /* Action for low memory */ -(void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } @end

我是ios编程的新手。 我将不胜感激任何帮助。 谢谢。

  1. 请把你的objective-c视图控制器转换成swift。 不要通过桥接头来导入它。

    2.使用以前在objective-c版本中使用的新转换类

    3.只需在桥接头中导入帧工作头文件。

将Objective-C代码转换为swift使用swiftify

编辑

这是转换的代码

两个文件都是组合的
