<h2>Introduction</h2>

<p>In this article I'll show you how to add Text-to-Speech (TTS) capabilities to your program.</p>

<p>You'll be able to do it with, essentially, 1 line of code, using the familiar standard <code>ostream</code> syntax.</p>

<p>Additionally, I'll show how using open source C++ tools can make
your code short (my whole code is less than 50 lines), reliable, more
robust and more general than the original APIs.</p>

<p>What I'll show:</p>

<ul>
<li>How to add simple TTS to your program. </li>

  <li>A simple use of <a href="http://synesis.com.au/software/comstl/">COMSTL</a> 
    and various other <a href="http://synesis.com.au/software/stlsoft/">STLSoft</a> 
    components. </li>

<li>A simple example of how to use <a href="http://www.boost.org/libs/iostreams/doc/index.html">boost::iostreams</a> </li>
</ul>

<h2>Background</h2>

<p>I recently had to add audio outputs to a program (running on Windows).</p>

<p><a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=5e86ec97-40a7-453f-b0ee-6583171b4530&amp;DisplayLang=en">Microsoft's SAPI SDK</a>
provides a COM interface through which wide character strings can be
spoken via SAPI's TTS engine. The Code Project has many articles
explaining how to use SAPI to varying degrees of complexity. So why
another?</p>

<p>Well, there were some additional features that I wanted that did not exist in those articles.</p>

<ol>
<li>As little or no COM hassle. Ideally, it should work within the simplest Console application. </li>

<li>Full (transparent) support for types other than wide-char. e.g. <code><span class="code-keyword">char</span>*</code>, <code>std::<span class="code-SDKkeyword">string</span></code>s and even <code><span class="code-keyword">int</span></code>s, <code><span class="code-keyword">float</span></code>s, etc. </li>

<li>Intuitive (or at least familiar) syntax </li>
</ol>

<p>To achieve these goals I developed <code>audio_ostream</code>.</p>

<p><code>audio_ostream</code> is a full-fledged <code>std::ostream</code> which supports any type that has an <code><span class="code-keyword">operator</span><span class="code-keyword">&lt;</span><span class="code-keyword">&lt;</span>()</code>.</p>
