Sapi Speech Dynamic Linking Library

SapiSpeech.dll - A Wrapper for Microsoft Speech API
Download it -> SapiSpeech

Overview :

SapiSpeech.dll is a dynamic linking library written by Ammar Qammaz to simplify the process of importing Speech without using managed-code :) in non Visual-Studio compiled applications.

The library contains very few calls , and in the future I plan to also provide an interface for speech recognition ( right now , only computer speech is included )

In order to use it , you will need a PC with Windows 9x/XP/Vista and The Speech API redistributables..
You can download version 5.1 The Speech API redistributables here , you propably want SpeechSDK51.exe ( Windows Vista users have 5.3 preinstalled so you don`t need it)

SapiSpeech.dll was compiled using Visual Studio 2003

Exports :

//BASIC FUNCTIONALITY
bool _stdcall InitSpeech() // Required one time at the start of the program
bool _stdcall UnInitSpeech() // Required one time at the end of the program

//SPEAKING
// consists of two parts , (1) passing a string to the library and (2) order the Sapi to speak

// PASSING STRINGS (For languages that do not have a char array data type)
void _stdcall Speech_PassNewString(unsigned int charlen) // Pass new string with a total of "charlen" characters
unsigned int _stdcall Speech_GetStringLength() // Get Length of string currently loaded
char _stdcall Speech_GetStringChar(unsigned int thech) // Return Character with character number "thech" (First character is character 0 , last character is character Speech_GetStringLength() -1 )
void _stdcall Speech_SetStringChar(unsigned int thech,char theval) // Pass Character with character number "thech" and value "theval" (First character is character 0 , last character is character Speech_GetStringLength() -1 )

//SPEAKING
void _stdcall SaySomething()
void _stdcall SayString(const char * thestr)
