That is very disappointing. Dectalk linux isn't going to go very far if the SDK costs $1700. This is really sad, I want to write applications for software synth, but there isn't much to choose from. I don't like the sound of festival. I will do it with viavoice but that is not a great alternative either. The eloquence SDK (viavoice actually uses that) is not cheap either). All I would need from the dectalk sdk is the damn .h header files! And there is only three of them! So I guess they are over $500 each. -- Doug > You have to buy the SDK which they will sell you for around $1700
