Freelancer uses UTF files to store several hundred sound bites in one file, for each of it's 20 or so voices.
We've tried creating new UTF files, and editing the related INI files, to no avail.
We also tried editing the existing files, but with no luck there, either.
Version 3.0, which is labeled v1.21 on Lancer's Reactor, is the only version ever made public that had any Privateer voices.
And that was an accidental release.
(I'd sent that version to be Alpha Tested, and the Tester went on vacation, no one else knew about it, so they released it. Buggiest release ever!)
There is a new UTF file ripper/compiler that looked promising over on LR, but with my file-corrupting-computer, I never got past a few simple tests.
The ripper will rip ever sound out of the UTF file, and write it to your HDD as a WAV file.
I had begun listening to every WAV file, and comparing it to the appropriate entry in the male/female space voice INI files.
Simply replacing the appropriate original WAV with a Privateer WAV worked fairly well in preliminary tests with the compiler.
(I only replaced one or two phrases.)
The main problem is that there are 2 INI's, 20 voice UTF's, and around 300 WAV files in each UTF file.
(And that's not including storyline, special character, and some base-specific UTF's.)
A VERY time-consuming project!
(To say the very least!)
