我正在寻找一种方法来知道espeak何时结束发言。有人告诉使用espeakEVENT_MSG_TERMINATED。但是，当我尝试将此部分放到我的代码中时，它给了我这个错误:
#include <espeak/speak_lib.h>
espeak_EVENT_TYPE;
if( espeak_EVENT_TYPE == espeakEVENT_MSG_TERMINATED)
{
do something;
}
编辑:我用这个简单的代码来使用
espeak:#include <string.h>
#include <malloc.h>
#include <espeak/speak_lib.h>
espeak_POSITION_TYPE position_type;
espeak_AUDIO_OUTPUT output;
char *path=NULL;
int Buflength = 1000, Options=0;
void* user_data;
t_espeak_callback *SynthCallback;
espeak_PARAMETER Parm;
char Voice[] = {"English"};
char text[30] = {"this is an english text"};
unsigned int Size,position=0, end_position=0, flags=espeakCHARS_AUTO, *unique_identifier;
int main(int argc, char* argv[] )
{
output = AUDIO_OUTPUT_PLAYBACK;
espeak_Initialize(output, Buflength, path, AUDIO_OUTPUT_SYNCHRONOUS ); //Options );
espeak_SetVoiceByName(Voice);
const char *langNativeString = "en";
espeak_VOICE voice = {0};
// memset(&voice, 0, sizeof(espeak_VOICE));
voice.languages = langNativeString;
voice.name = "US";
voice.variant = 2;
voice.gender = 1;
espeak_SetVoiceByProperties(&voice);
Size = strlen(text)+1;
espeak_Synth( text, Size, position, position_type, end_position, flags,unique_identifier, user_data );
espeak_Synchronize( );
return 0;
}

错误:
最佳答案
espeak_EVENT_TYPE;
这行对编译器不敏感。
espeak_EVENT_TYPE是一种数据类型。它不是可以与espeakEVENT_MSG_TERMINATED这样的值进行比较的变量。为了声明变量，语法为:espeak_EVENT_TYPE an_event_type {};
if (an_event_type == espeakEVENT_MSG_TERMINATED) {
/* ... */
但是，如果执行此操作，那么刚才创建的
an_event_type变量实际上将不包含有关任何真实espeak事件的任何信息。而且，对于任何实际消息是否已终止，它当然不会说什么。从espeak接收真实事件信息
为了获取有关消息是否终止的信息，程序需要从espeak库中获取
espeak_EVENT_TYPE类型的变量。浏览this header，将
espeak_EVENT_TYPE用作espeak_EVENT结构的一部分。要接收espeak_EVENT通知，有必要编写一个将由espeak库调用的函数。 (这称为“回调”功能)。然后，通过调用espeak_SetSynthCallback将回调函数注册到库中。从同一 header ，回调函数的原型(prototype)必须如下所示:
放在一起，我们需要一个函数，它像一个数组一样循环遍历
events变量，直到遇到类型为0的事件为止。然后该函数需要返回0才能继续语音 Activity 。int receive_espeak_events(short *wav, int numsamples, espeak_EVENT *event)
{
while (event->type != espeakEVENT_LIST_TERMINATED) {
if (event->type == espeakEVENT_MSG_TERMINATED) {
/* do something */
}
++event; // Examine the next event.
}
return 0; // Continue speaking.
}
要告诉espeak调用此函数，请在开始任何综合操作之前将该函数传递给
espeak_SetSynthCallback。espeak_SetSynthCallback(receive_espeak_events);
