A long time ago, I purchased a TTS product from Loquendo and I was looking at updating to the product they demo here: http://www.loquendo.com/en/demo-center/tts-demo/english/
As an aside, the only other TTS that I have found with even better quality is: http://www.ispeech.org/
but it is an expensive SAAS solution. I provide this URL as an FYI only.
It is important that it is stand-alone (NOT SAAS) and allows for multiple languages. The above Loquendo demo URL is quite remarkable. Unfortunately, they offer no method of actually purchasing these products (nor the voices). They provide a link to Nuance but the Nuance site doesn't even mention TTS products. I am confused?!? Email request go unanswered... yet they continue to leave that amazing demo page up (about 2 years old now). Does the product (that created these audio demos) exist or is it actually vaporware?
Anyhow my questions are:
1. How can I purchase this Loquendo [Windows based) TTS product and various voices?
2. If Q1 is unlikely, than what other TTS product (of similar or better output) is available for purchase?
3. Why does it seem as though TTS development has come to standstill? The URLs provided are both from about two years ago and I haven't seen any improvements since that time.
NOTE: I have already reviewed the TTS Wikipedia information, checked out IVONA and a few others listed there. CereProc is pretty amazing and may actually answer my EE question. However, I am hopefully looking for someone to add to what is already available on this Wiki entry and what I already know.
