我们这学期刚学的凌阳61板,语音程序有A2000,S480,S2403种算法,我先给个A2000的,还需要的话发消息给我,一起学习啦!#include "A2000.h"
#define SPEECH_1 0
#define DAC1 1
#define DAC2 2
#define Ramp_UpDn_Off 0
#define Ramp_UpDn_On 3
#define Manual 0
#define Auto 1
#define Full 1
#define Empty 2
#define Mode 1
//===============================================================================================
/颤橘/ 函数： main()
// 描述：主函数
//===============================================================================================
main()
{
extern long RES_WW_24K_SA,RES_WW_24K_EA //定义语音资源的首末地址标号
long int Addr //定义地址变量
int Ret = 0 //定义获取语音数据变量并初始化
if(Mode == 1) //采用自动方式播放
{
SACM_A2000_Initial(1)//自动方式播放初始化
SACM_A2000_Play(SPEECH_1,DAC1,Ramp_UpDn_On) //销键定义语音索引号、播放通道、允许亏洞巧音量增/减调节
while(1){
F_ClearWatchdog()
SACM_A2000_ServiceLoop()} //获取语音数据并将其填入解码队列
}
if(Mode == 0)//采用非自动方式播放
{
Addr=RES_WW_24K_SA//送入语音队列的首址
SACM_A2000_Initial(0) //非自动方式播放的初始化
SACM_A2000_InitDecoder(DAC1) //开始对A2000的语音数据以非自动方式解码
while(SACM_A2000_TestQueue()!=Full) //测试并获取语音队列的状态
{
Ret=SP_GetResource(Addr) //从资源文件里获取一个字型语音数据
SACM_A2000_FillQueue(Ret) //获取语音编码数据并填入语音队列等候解码
Addr++
}
while(1)
{
if(SACM_A2000_TestQueue()!=Full)
{
Ret =SP_GetResource(Addr)
SACM_A2000_FillQueue(Ret)
Addr++
}
if(Addr<RES_WW_24K_EA ) //如果该段语音未播完，即未到达末地址时
SACM_A2000_Decoder() //获取资源并进行解码，再通过中断服务子程序送入DAC通道播放
else
SACM_A2000_Stop() //否则，停止播放
F_ClearWatchdog()//清看门狗
}
}
}
首先你要引用 DotNetSpeech然后
创建SpeechRecognitionEngine 对象
下面的伍源代码可以让此亏系统获取腔扒态语音并且识别
SRE = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("zh-CN"))//中文
SRE.LoadGrammar(new DictationGrammar())//所有语言
SRE.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(SRE_SpeechRecognized)//系统接受后的事件
SRE.SetInputToDefaultAudioDevice()//设置默认输入设备
微软MSDN里面有详细的介绍，望采纳。
