>
> Here's some of the TTS engines I've run across with some pros/cons:
>
> Festivate Lite (flite)
> Pros:
> - Free (comes with FS)
> - simple to use
> - 16K voice sounds decent
> - Completely customizable
> Cons:
> - 8K voice sounds horrible over cell phone
>
> NeoSpeech (VoiceWare) (around $300/port for 1 voice + $75 each addl voice)
> Pros:
> - My selection for best soundig voices
> - Recently select by Stephen Hawkings for his voice (geek points!)
> - Lots of Languages supported
> - Free trial available
> Cons:
> - Custom C-Based API (FS interface coming soon)
> - Large file size (Engine + SDK + 1 Voice = 900MB)
> - Support is lacking (Company beed in Korean, time zone issues, etc)
>
> Nuance ($500/port for 1 voice)
> Pros:
> - Wide Variety of Products
> - Support MRCP
> - Supports ASR as well (add'l fees)
> - Excellent support
> - Free trial
> - Decent sounding voices at 8K and 16K
> - Wide range of tuning parameters
> Cons:
> - Pricey
> - Limited voice selection
> - Limited support for 64-bit linux
>
> AT&T (NaturalVoice) (no pricing info available)
> Pros:
> - Big company (solid in marketplace)
> - Good suppport (user and developer)
> - ASP model means no software to maintain
> Cons:
> - ASP model incurs delay
> - Voices sound too digitized
> - Limited support for 64-bit linux
>
> Loquendo ($500/port for 1 voice + 15% addl voice)
> Pros:
> - Good sounding voices (almost as good as NeoSpeech)
> - Wide variety of languages
> - Excellent support

> - Support ASR and Voice Recognition as well. (add'l fees)
> - Small footprint (< 150MB)
> Cons:
> - Pricey
> - Complicated install process
> - Limited management/tuning capabilities
>
> In the end, it was down to NeoSpeech or Loquendo for our application.
> We are currently running tests with NeoSpeech and assuming all goes
> well, we will select them. Though don't let that color your opinion
> too much after several "focus groups" we discovered the most important
> element in the equation is does your customer/boss like the sound of
> the voices, and that is a completely subjective decision.
