Question

我们正在制作iPhone应用程序，客户希望将提醒作为语音消息。

要求是用户将设置他们想要提醒的时间和文本。

使用文字，我会转换为语音，并在触发提醒时播放音频文件。

为此，我计划使用谷歌服务

http://www.translate.google.com/translate_tts?tl=ar&q=%D9%85%D8%B1%D8%AD%D8%A8%D8%A7%20%D8%B5%D8%AF%D9%8A%D9%82%D8%8C%20%D9%83%D9%8A%D9%81%20%D8%AD%D8%A7%D9%84%D9%83%D8%9F

http://www.translate.google.com/translate_tts?tl=en&q=helloE%20friend

播放这些文字并下载相同的音频文件。

NSString* userAgent = @"Mozilla/5.0";

NSURL *url = [NSURL URLWithString:[@"http://www.translate.google.com/translate_tts?tl=en&q=helloE%20friend" 
                                   stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];


NSMutableURLRequest* request = [[[NSMutableURLRequest alloc] initWithURL:url] autorelease];

[request setValue:userAgent forHTTPHeaderField:@"User-Agent"];


NSURLResponse* response = nil;
NSError* error = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:request
                                     returningResponse:&response
                                                 error:&error];



[data writeToFile:@"/var/tmp/tts.mp3" atomically:YES];

我可以使用这些代码，但客户不想上网。

是否有任何图书馆可以在没有互联网的情况下进行文字转语音转换（如siri正在做的那样）？

关于此的任何信息都会很棒。

Answer 1

使用AVSpeechSynthesizer

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Some random text that you want to be spoken"];
[utterance setRate:0.7];
[synthesizer speakUtterance:utterance];

Answer 2

这仅适用于iOS 7以上

以下是我使用的代码。

NSString *myStr;

//    myStr = @"Hello friend, how are you?";
myStr = @"مرحبا صديق، كيف حالك؟";

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];

AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:myStr];
[utterance setRate:0.2f];
//    utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-us"];
utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"ar-SA"];
[synthesizer speakUtterance:utterance];
