I'm developing a little app where in this app, have to have a voice who say some words.
Can I use the voice that some programs uses like "Google Translate", "Vozme" or similar? If not, how can I do this?

AVSpeechSynthesizer Class Reference is available from iOS7. The documentation is very good. Be sure to link the AVFoundation framework to your project.
Here is a working example that speaks text entered from a UITextField when a UIButton is tapped - (assuming a UIViewController sub-class named YOURViewController)
in .h
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#interface YOURViewController : UIViewController <AVSpeechSynthesizerDelegate, UITextFieldDelegate> {
IBOutlet UITextField *textFieldInput;// connect to a UITextField in IB
}
- (IBAction)speakTheText:(id)sender;// connect to a UIButton in IB
#end
and in .m
#import "YOURViewController.h"
#interface YOURViewController ()
#end
#implementation YOURViewController
- (IBAction)speakTheText:(id)sender {
// create string of text to talk
NSString *talkText = textFieldInput.text;
// convert string
AVSpeechUtterance *speechUtterance = [self convertTextToSpeak:talkText];
// speak it...!
[self speak:speechUtterance];
}
- (void)viewDidLoad {
[super viewDidLoad];
}
- (AVSpeechUtterance*)convertTextToSpeak:(NSString*)textToSpeak {
AVSpeechUtterance *speechUtterance = [[AVSpeechUtterance alloc] initWithString:textToSpeak];
speechUtterance.rate = 0.2; // default = 0.5 ; min = 0.0 ; max = 1.0
speechUtterance.pitchMultiplier = 1.0; // default = 1.0 ; range of 0.5 - 2.0
speechUtterance.voice = [self customiseVoice];
return speechUtterance;
}
- (AVSpeechSynthesisVoice*)customiseVoice {
NSArray *arrayVoices = [AVSpeechSynthesisVoice speechVoices];
NSUInteger numVoices = [arrayVoices count];
AVSpeechSynthesisVoice *voice = nil;
for (int k = 0; k < numVoices; k++) {
AVSpeechSynthesisVoice *availCustomVoice = [arrayVoices objectAtIndex:k];
if ([availCustomVoice.language isEqual: #"en-GB"]) {
voice = [arrayVoices objectAtIndex:k];
}
// This logs the codes for different nationality voices available
// Note that the index that they appear differs from 32bit and 64bit architectures
NSLog(#"#%d %#", k, availCustomVoice.language);
}
return voice;
}
- (void)speak:(AVSpeechUtterance*)speechUtterance {
AVSpeechSynthesizer *speechSynthesizer = [[AVSpeechSynthesizer alloc] init];
speechSynthesizer.delegate = self;// all methods are optional
[speechSynthesizer speakUtterance:speechUtterance];
}
#end
