20 public class Speach
21 {
22 private static Speach _Instance = null;
23 private SpeechLib.SpVoiceClass voice = null;
24 private Speach()
25 {
26 BuildSpeach();

28 public static Speach instance()
29 {
30 if (_Instance == null)
31 _Instance = new Speach();
32 return _Instance;

34 private void SetChinaVoice()
35 {
36 voice.Voice = voice.GetVoices(string.Empty, string.Empty).Item(3);
