Microsoft Project Oxfordには、優れた音声認識 API と、IOS 上の Objective-C に関する説明があります。入門ガイドに従って簡単にビルドします。ただし、Swift 言語に変換するのに苦労しています。
最初に迅速なプロジェクトを作成しました。ブリッジ ヘッダー ファイル (ProjectName-Bridging-Header.h) を作成し、このファイルに次のコードを挿入しました。
#import "SpeechRecognitionService.h"
Objective-C のヘッダー ファイルと実装ファイルの両方を ViewController.swift に変換したいと考えています。
ViewController.h の内容:
#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 の内容:
#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 */

私はiosプログラミングの初心者です。これについて何か助けていただければ幸いです。ありがとう。
