'''Speech Listener Element''' allows real-time recognition of spoken words delivered through microphone line on a sound card. The speech is recognized into a text which can be used for determining a participant response. The elements requires [^http://msdn.microsoft.com/en-us/library/ms723627%28v=vs.85%29.aspx|Microsoft Speech API (SAPI)] to be installed and properly configured on a computer.<br><br>
{TOC}

== Installation ==
Microsoft Speech API is included in Window 7 and Windows Vista. To make the element working in Window XP, Microsoft SAPI can be installed using Microsoft Office installation. Here is an [^http://support.microsoft.com/kb/306537|MS article] describing the SAPI installation process for Windows XP.
