      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Problem with SAPI Dynamic Grammars in C++

1 post in this topic

Good morning. I have been making a Speech to Text program using SAPI and am having some problems with loading, activating and deactivating dynamic grammars. Basically I am displaying a picture on the screen. If the user states the correct response, as defined by the dynamic grammar rule, then that rule is deactivated, and another picture is displayed and its corresponding grammar rule is activated.

I want the dynamic rules to be topLevel, so they just have to state the object without any prefix etc.

My problem is the rules activating/ deactivating do not seem to be consistent. Sometimes the grammar will accept any of the rules, sometimes it will accept only the correct rule.

Any help would be appreciated. If you need more info/ code please let me know. Thanks!

I am pretty sure it is something I am missing when it comes to the grammar rules/ word transition. The other thing I thought might be possible was that I am somehow creating a rule with the memory address of LPCWSTR pikk as opposed to the actual data - but that doesn't seem like it is the problem since the first parameter of GetRule is a LPCWSTR - unless I am converting incorrectly?


Loading dynamic grammar rules:

[CODE]
//curNumb = current number of exercise
//curNumbID = curNumb + numOffest (500) so I reserve #1-500 for whatever other hard-coded grammar rules I add
std::wstring stemp;
LPCWSTR pikk;
//add in the grammar:
//reserve curNumb
int reserveNum = curNumb;
//loop through all object_data and load dynamic rules into grammar:
for(int pip = 0; pip < data.numObjects.size(); pip++)
{
stemp = s2ws(data.object_data[curNumb].title);
pikk = stemp.c_str();
hr = g_cpCmdGrammar->GetRule(pikk, data.object_data[curNumb].programID, SPRAF_TopLevel, TRUE, &hStateTravel);
if(FAILED(hr))
{
ErrorDescription(hr);
}
//loop through all words in object_data
std::list<std::string>::iterator st_it = data.object_data[curNumb].words.begin();
for(; st_it != data.object_data[curNumb].words.end(); st_it++)
{
std::cout<<"adding word: "<<(*st_it)<<"\n";
stemp = s2ws((*st_it));
pikk = stemp.c_str();
hr = g_cpCmdGrammar->AddWordTransition(hStateTravel, NULL, pikk, L"", SPWT_LEXICAL, 1, NULL);
if(FAILED(hr))
{
ErrorDescription(hr);
}
}
curNumb++;
}
//reset curNumb back to reserveNum
curNumb = reserveNum;
//activate curNumb grammar rule
stemp = s2ws(data.object_data[curNumb].title);
pikk = stemp.c_str();
std::cout<<"activate new rules "<<curNumbID<<"/"<<curNumb<<" ("<<data.object_data[curNumb].title<<")\n";
hr = g_cpCmdGrammar->SetRuleIdState(curNumbID, SPRS_ACTIVE);
if(FAILED(hr))
{
ErrorDescription(hr);
std::cout<<"FAILURE at activate previous rules "<<curNumbID<<"/"<<curNumb<<" ("<<data.object_data[curNumb].title<<")\n";
}
else
{
std::cout<<"ruleActivated...\n";
}

hr = g_cpCmdGrammar->Commit(0);
[/CODE]

//deactivate old rule/ activate new rule code:
[CODE]
std::cout<<"curScore++ ("<<curScore<<"->";
curScore++;
std::cout<<curScore<<")\n";
//clear old exercise:

std::wstring stemp = s2ws(data.object_data[curNumb].title);
LPCWSTR pikk = stemp.c_str();
std::cout<<"deactivate previous rules "<<curNumbID<<"/"<<curNumb<<" ("<<data.object_data[curNumb].title<<")\n";
hr = g_cpCmdGrammar->SetRuleIdState(curNumbID, SPRS_INACTIVE);
if(FAILED(hr))
{
ErrorDescription(hr);
std::cout<<"FAILURE at deactivate previous rules "<<curNumbID<<"/"<<curNumb<<" ("<<data.object_data[curNumb].title<<")\n";
}
else
{
std::cout<<"ruleDeactivated...\n";
}
curNumb++;
if(curNumb > data.numObjects.size())
{
curNumb = 1;
}
curNumbID = curNumb + exerciseOffset;
//activate next rule:
stemp = s2ws(data.object_data[curNumb].title);
pikk = stemp.c_str();
std::cout<<"activate new rules "<<curNumbID<<"/"<<curNumb<<" ("<<data.object_data[curNumb].title<<")\n";
hr = g_cpCmdGrammar->SetRuleIdState(curNumbID, SPRS_ACTIVE);
if(FAILED(hr))
{
ErrorDescription(hr);
std::cout<<"FAILURE at activate previous rules "<<curNumbID<<"/"<<curNumb<<" ("<<data.object_data[curNumb].title<<")\n";
}
else
{
std::cout<<"ruleActivated...\n";
}
[/CODE]

I have broken everything down to its simplest form:
[url="http://www.mediafire.com/?xwevgekf8ndrrpv"]http://www.mediafire.com/?xwevgekf8ndrrpv[/url]
(should be able to download from above link without having to wait/ enter any captcha)

This project contains all the files for a simple WINAPI program utilizing SAPI speech recognition.
It was created in VS2010 using the default Win32 project settings.

*After compiling and executing the program a window will be displayed with a word (gloves).
*After saying the command "START" the program will load the first dynamic grammar word/ rule(which in this case would be the word "GLOVES")
*The program is then supposed to start listening for the word displayed. If you say "GLOVES" it will reset the dynamic grammar and load the next word. There are four words in total (gloves, fox, computer, dog).

**My issue is that the rules are not consistent. At times I can say "GLOVES" when it is supposed to only accept "COMPUTER"
