\section{wxTTS overview}\label{ttsoverview} 
 
wxMbrola is a wrapper around Mbrola functionality under Windows, taking 
phoneme files or strings and producing audio output. wxFreePhone is a wrapper 
around the augmented FreePhone package, taking text and generating Mbrola-compatible 
phoneme strings or files. By using both these classes in a program, it is straightforward 
to produce talking English applications. 
 
\wxheading{Using the classes under Windows} 
 
You need to include {\tt tts/wxmbrola.h} and {\tt tts/freephone.h}, and link with 
 {\tt freephoneX.lib}, {\tt wxmbrolaX.lib} and {\tt mbrplay.lib} where X differs 
according to whether you are using debug, release, MFC, wxWindows or plain WIN32: 
 
{\small\begin{verbatim} 
lib/wxmbrola.lib                    ; wxMbrola library (WIN32 release) 
lib/wxmbrola_d.lib                  ; wxMbrola library (WIN32 debug) 
lib/wxmbrola_mfc.lib                ; wxMbrola library (MFC release) 
lib/wxmbrola_mfc_d.lib              ; wxMbrola library (MFC debug) 
lib/wxmbrola_wx.lib                 ; wxMbrola library (wxWindows release) 
lib/wxmbrola_wx_d.lib               ; wxMbrola library (wxWindows debug) 
lib/freephone.lib                   ; wxFreePhone library (WIN32 release) 
lib/freephone_d.lib                 ; wxFreePhone library (WIN32 debug) 
lib/freephone_mfc.lib               ; wxFreePhone library (MFC release) 
lib/freephone_mfc_d.lib             ; wxFreePhone library (MFC debug) 
lib/freephone_wx.lib                ; wxFreePhone library (wxWindows release) 
lib/freephone_wx_d.lib              ; wxFreePhone library (wxWindows debug) 
\end{verbatim} 
} 
 
Each class (wxMbrola and wxFreePhone) requires Init() to be called after the object 
is constructed. You can then use methods to produce phonemes and speech. Normally 
these objects would last the lifetime of the application (to avoid the overhead of 
multiple initialisation) but the following example uses stack objects: 
 
{\small\begin{verbatim} 
    wxFreePhone freephone("english"); // Use english.key/idx/dct files 
	freephone.Init(); 
 
    wxMbrola mbrola; 
    mbrola.Init(); 
    mbrola.SetCurrentDatabase("en1"); 
 
    char* phonemes; 
    if (freephone.TextToPhoneme("This is a test.", &phonemes)) 
        mbrola.Play(phonemes, TRUE); 
\end{verbatim} 
} 
 
\wxheading{Using MFC, native Windows, or wxWindows} 
 
You can change settings in {\tt wxmbrola.h} and {\tt freephone.h} to specify 
which framework to use, or simply use the way that the supplied VC++ makefiles use 
to specify the kind of build required: 
 
\begin{itemize}\itemsep=0pt 
\item To use plain WIN32, do nothing special. 
\item To use MFC, define _AFXDLL. 
\item To use wxWindows, define __WXMSW__. 
\end{itemize}
