I paraphrased what I previously read on the web site. I just visited the site and find that the quote I used has been removed, but a whole section on performance has been added. In short, Flite is faster to start up and FreeTTS is faster to process text and speak it. Here is the section from the site: How does FreeTTS perform? We compared the performance of FreeTTS with that of Flite (original C version) on a machine with this configuration: *?single 296MHz CPU SPARC v9 processor *?SolarisTM 8 in 64-bit mode *?Java 2 SDK, Standard Edition, v 1.4 We rendered the first two chapters of Alice's Adventures in Wonderland by Lewis Carroll (about 20 minutes of text), and the entire text of Jules Verne's Journey to the Center of the Earth (about 8 hours of text) using both Flite and FreeTTS. The results are summarized below: Single CPU 296MHz SPARC v9 Flite FreeTTS Loading Time for 'Alice' text 0.0s 4.1s Processing Time for 'Alice' text 43.7s 24.1s Loading Time for 'Journey' text 0.0s 7.0s Processing Time for 'Journey' text 1019.2s 341.0s Time to first Sample (10 word sentence) 195ms 41ms On a 2-CPU system with the following configuration: *?Dual 360MHz CPU SPARC v9 Processor system *?SolarisTM 8 in 64-bit mode *?Java 2 SDK, Standard Edition, v 1.4 The results are summarized below: Dual CPU 360MHz SPARC v9 Flite FreeTTS Loading Time for 'Alice' text 0.0s 2.9s Processing Time for 'Alice' text 35.7s 14.2s Loading Time for 'Journey' text 0.0s 3.8s Processing Time for 'Journey' text 842.7s 189.5s Time to first Sample (10 word sentence) 165ms 33ms
