<div class="h5">&gt; I&#39;ve spent the last 2-3 months on researching TTS and ASR for FS for a<br>&gt; project.  Best TTS depends on what you consider important.  Also, how<br>&gt; do you plan on using it.<br>&gt;<br>&gt; Here&#39;s some of the TTS engines I&#39;ve run across with some pros/cons:<br>

&gt;<br>&gt; Festivate Lite (flite)<br>&gt; Pros:<br>&gt; - Free (comes with FS)<br>&gt; - simple to use<br>&gt; - 16K voice sounds decent<br>&gt; - Completely customizable<br>&gt; Cons:<br>&gt; - 8K voice sounds horrible over cell phone<br>

&gt;<br>&gt; NeoSpeech (VoiceWare) (around $300/port for 1 voice + $75 each addl voice)<br>&gt; Pros:<br>&gt; - My selection for best soundig voices<br>&gt; - Recently select by Stephen Hawkings for his voice (geek points!)<br>

&gt; - Lots of Languages supported<br>&gt; - Free trial available<br>&gt; Cons:<br>&gt; - Custom C-Based API (FS interface coming soon)<br>&gt; - Large file size (Engine + SDK + 1 Voice = 900MB)<br>&gt; - Support is lacking (Company beed in Korean, time zone issues, etc)<br>

&gt;<br>&gt; Nuance ($500/port for 1 voice)<br>&gt; Pros:<br>&gt; - Wide Variety of Products<br>&gt; - Support MRCP<br>&gt; - Supports ASR as well (add&#39;l fees)<br>&gt; - Excellent support<br>&gt; - Free trial<br>&gt; - Decent sounding voices at 8K and 16K<br>

&gt; - Wide range of tuning parameters<br>&gt; Cons:<br>&gt; - Pricey<br>&gt; - Limited voice selection<br>&gt; - Limited support for 64-bit linux<br>&gt;<br>&gt; AT&amp;T (NaturalVoice) (no pricing info available)<br>&gt; Pros:<br>

&gt; - Big company (solid in marketplace)<br>&gt; - Good suppport (user and developer)<br>&gt; - ASP model means no software to maintain<br>&gt; Cons:<br>&gt; - ASP model incurs delay<br>&gt; - Voices sound too digitized<br>

&gt; - Limited support for 64-bit linux<br>&gt;<br>&gt; Loquendo ($500/port for 1 voice + 15% addl voice)<br>&gt; Pros:<br>&gt; - Good sounding voices (almost as good as NeoSpeech)<br>&gt; - Wide variety of languages<br>
&gt; - Excellent support<br>
&gt; - Has free 30 day trial<br>&gt; - Supports MRCP<br>&gt; - Support ASR and Voice Recognition as well. (add&#39;l fees)<br>&gt; - Small footprint (&lt; 150MB)<br>&gt; Cons:<br>&gt; - Pricey<br>&gt; - Complicated install process<br>

&gt; - Limited management/tuning capabilities<br>&gt;<br>&gt; In the end, it was down to NeoSpeech or Loquendo for our application.<br>&gt;  We are currently running tests with NeoSpeech and assuming all goes<br>&gt; well, we will select them.  Though don&#39;t let that color your opinion<br>

&gt; too much after several &quot;focus groups&quot; we discovered the most important<br>&gt; element in the equation is does your customer/boss like the sound of<br>&gt; the voices, and that is a completely subjective decision.<br>
