语音翻译采用语音听写接口，设置业务参数即可实现语音翻译功能。目前支持英文转中文，中文转英文，后续其他功能请注意浏览讯飞开放平台。

1. //需要实现IFlyRecognizerViewDelegate或者IFlySpeechRecognizerDelegate识别协议

3. //创建语音识别对象
4. _iFlySpeechRecognizer = [IFlySpeechRecognizer sharedInstance];

6. //必要参数设置
7. //设置为听写模式
8. [_iFlySpeechRecognizer setParameter: @"iat" forKey: [IFlySpeechConstant IFLY_DOMAIN]];
9. [_iFlySpeechRecognizer setParameter: @"1" forKey: [IFlySpeechConstant ASR_SCH]];
10. [_iFlySpeechRecognizer setParameter: @"translate" forKey: @”addcap”];

12. //中文转英文
13. [_iFlySpeechRecognizer setParameter: @"zh" forKey: @”orilang”];
14. [_iFlySpeechRecognizer setParameter: @"en" forKey: @”translang”];

16. //英文转中文
17. [_iFlySpeechRecognizer setParameter: @"en" forKey: @”orilang”];
18. [_iFlySpeechRecognizer setParameter: @"zh" forKey: @”translang”];

20. //启动服务
21. [_iFlySpeechRecognizer start];

23. //SDK的回调仍然采用IFlySpeechRecognizerDelegate协议实现。

25. //注意：当从翻译功能转换其他业务时，需要清空参数
26. //[_iFlySpeechRecognizer setParameter: @"" forKey: @”params”];
