Я ищу способ узнать, когда espeak закончил, он говорит. Кто-то сказал использовать espeakEVENT_MSG_TERMINATED. Но когда я пытаюсь поместить эту часть в мой код, это дает мне эту ошибку:
#include <espeak/speak_lib.h>
espeak_EVENT_TYPE;
if( espeak_EVENT_TYPE == espeakEVENT_MSG_TERMINATED)
{
do something;
}
application.cpp: 31: 1: ошибка: объявление ничего не объявляет
[-fpermissive] espeak_EVENT_TYPE; ^ application.cpp: в функции
'Void speech (char *)': application.cpp: 116: 27: ошибка: ожидается
первичное выражение перед токеном ‘==’
if (espeak_EVENT_TYPE == espeakEVENT_MSG_TERMINATED)
РЕДАКТИРОВАТЬ: я использую этот простой код для использования 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;
}
