我怎样才能发送音频使用websocket微软翻译

Question

我已经创建了一个应用程序来翻译文本到文本和语音文本。 我已经把文字和文字做成了speech.i，我没有把语音翻译成文本。

我使用这个演示https://github.com/bitmapdata/MSTranslateVendor它只会将文本转换为文本和文本到语音。

我在堆栈溢出搜索它会给我像使用websocket发送音频的解决方案，但我不知道如何发送它。而且我是新的websocket编程。

请帮助我如何使用websocket发送音频。

我创建音频像下面的方法，但我不知道如何发送它。

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    settings = [[NSMutableDictionary alloc] init]; 
    [settings setValue:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey]; 
    [settings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; 
    [settings setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey]; 
    [settings setValue:[NSNumber numberWithInt: 16] forKey:AVLinearPCMBitDepthKey]; 
    [settings setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsBigEndianKey]; 
    [settings setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsFloatKey]; 
    [settings setValue:[NSNumber numberWithInt: AVAudioQualityHigh] forKey:AVEncoderAudioQualityKey]; 


    NSArray *pathComponents = [NSArray arrayWithObjects: 
           [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], 
           @"Sohil.wav", 
           nil]; 
    outputFileURL = [NSURL fileURLWithPathComponents:pathComponents]; 
    NSLog(@"Record URL : %@",outputFileURL); 

    // Setup audio session 
    AVAudioSession *session = [AVAudioSession sharedInstance]; 
    [session setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; 

    // Initiate and prepare the recorder 
    recorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:settings error:nil]; 
    recorder.delegate = self; 
    recorder.meteringEnabled = YES; 
    [recorder prepareToRecord]; 
} 

- (IBAction)recordStart:(id)sender { 

    AVAudioSession *session = [AVAudioSession sharedInstance]; 
    [session setActive:YES error:nil]; 
    [recorder record]; 

} 

- (IBAction)recordStop:(id)sender { 
    [recorder stop]; 
    AVAudioSession *audioSession = [AVAudioSession sharedInstance]; 
    [audioSession setActive:NO error:nil]; 

} 

，并将其转换：

-(NSData*) stripAndAddWavHeader:(NSData*) wav { 
    unsigned long wavDataSize = [wav length] - 44; 

    NSData *WaveFile= [NSMutableData dataWithData:[wav subdataWithRange:NSMakeRange(44, wavDataSize)]]; 

    NSMutableData *newWavData; 
    newWavData = [self addWavHeader:WaveFile]; 

    return newWavData; 
} 
- (NSMutableData *)addWavHeader:(NSData *)wavNoheader { 

    int headerSize = 44; 
    long totalAudioLen = [wavNoheader length]; 
    long totalDataLen = [wavNoheader length] + headerSize-8; 
    long longSampleRate = 22050.0; 
    int channels = 1; 
    long byteRate = 8 * 44100.0 * channels/8; 



    Byte *header = (Byte*)malloc(44); 
    header[0] = 'R'; // RIFF/WAVE header 
    header[1] = 'I'; 
    header[2] = 'F'; 
    header[3] = 'F'; 
    header[4] = (Byte) (totalDataLen & 0xff); 
    header[5] = (Byte) ((totalDataLen >> 8) & 0xff); 
    header[6] = (Byte) ((totalDataLen >> 16) & 0xff); 
    header[7] = (Byte) ((totalDataLen >> 24) & 0xff); 
    header[8] = 'W'; 
    header[9] = 'A'; 
    header[10] = 'V'; 
    header[11] = 'E'; 
    header[12] = 'f'; // 'fmt ' chunk 
    header[13] = 'm'; 
    header[14] = 't'; 
    header[15] = ' '; 
    header[16] = 16; // 4 bytes: size of 'fmt ' chunk 
    header[17] = 0; 
    header[18] = 0; 
    header[19] = 0; 
    header[20] = 1; // format = 1 
    header[21] = 0; 
    header[22] = (Byte) channels; 
    header[23] = 0; 
    header[24] = (Byte) (longSampleRate & 0xff); 
    header[25] = (Byte) ((longSampleRate >> 8) & 0xff); 
    header[26] = (Byte) ((longSampleRate >> 16) & 0xff); 
    header[27] = (Byte) ((longSampleRate >> 24) & 0xff); 
    header[28] = (Byte) (byteRate & 0xff); 
    header[29] = (Byte) ((byteRate >> 8) & 0xff); 
    header[30] = (Byte) ((byteRate >> 16) & 0xff); 
    header[31] = (Byte) ((byteRate >> 24) & 0xff); 
    header[32] = (Byte) (2 * 8/8); // block align 
    header[33] = 0; 
    header[34] = 16; // bits per sample 
    header[35] = 0; 
    header[36] = 'd'; 
    header[37] = 'a'; 
    header[38] = 't'; 
    header[39] = 'a'; 
    header[40] = (Byte) (totalAudioLen & 0xff); 
    header[41] = (Byte) ((totalAudioLen >> 8) & 0xff); 
    header[42] = (Byte) ((totalAudioLen >> 16) & 0xff); 
    header[43] = (Byte) ((totalAudioLen >> 24) & 0xff); 

    NSMutableData *newWavData = [NSMutableData dataWithBytes:header length:44]; 
    [newWavData appendBytes:[wavNoheader bytes] length:[wavNoheader length]]; 
    return newWavData; 
} 

Answer 1

您可以使用Microsoft Cognitive-Speech-STT-iOS工作完美语音到文本。

1）首先你不会对Register App

2）现在，你想订阅的关键兵语音注册您的应用程序 - 预览使用此键在您的演示项目上setting.plist提交其做工精细。你可以得到两把钥匙使用任何一把钥匙。
