//this.audioPlayer = PlayerFactory.CreateAudioPlayer(0, 16000, 2, 16, 3);
}

public static SpeakerHelper getIns()
{
return speaker;
}

/// <summary>
/// 播放数据
/// </summary>
/// <param name="buffer"></param>
public void speak(byte[] buffer)
{
if (this.audioPlayer != null)
{
//Debug.WriteLine("audioData :" + audioData.Length);
this.audioPlayer.Play(buffer);
}
}

public void stop()
{
if (this.audioPlayer != null)
{
this.audioPlayer.Clear();
this.audioPlayer.Dispose();
this.audioPlayer = null;
}
}
}
}

如果音频播放没有声音，请查看麦克风与扬声器的音量是否为零或禁用了，查看方式为进入控制面板-声音-扬声器(如果没有接设备可能没有)-属性-级别
