おはよう、

googleTTS を使用して文字列を音声に変換する次の iPhone アプリがあり、ダウンロードしたデータを実際に再生することに固執しています。誰かが私が何も聞こえない理由を理解するのを手伝ってくれませんか.

    googleTTS = [[RJGoogleTTS alloc]init];

    [googleTTS convertTextToSpeech:@"How are you today user?"];

}

    NSLog(@"here are the bytes downloaded, %d", [self.downloadedData length]);


    NSString *txt = [[NSString alloc] initWithData:downloadedData encoding: NSASCIIStringEncoding];

ARCを使用していますか？その場合、自動的に nil に設定されないようにオーディオを保持する必要があります。次のプロパティを rjgoogletts のヘッダー ファイルに追加すると、出来上がりです! @property (nonatomic, strong) AVAudioPlayer *audioPlayer; お役に立てれば。ジム
