Thank you dsmid
Now there's a possibility to switch multiple voice packs:

Should you need to switch more than two voices, install launchpad and copy provided usertts.ini file to *launchpad* directory.
Then copy the second voice pack to *usertts/data2*, the third one to *usertts/data3* etc. You can have up to five voice packs.
Reload launchpad (SHIFT SHIFT SPACE) and then you can switch the voice packs with these shortcuts:

1. SHIFT T Q - *usertts/data*
2. SHIFT T W - *usertts/data2*
3. SHIFT T E - *usertts/data3*
4. SHIFT T R - *usertts/data4*
5. SHIFT T T - *usertts/data5*

Really nice! Thank you!
When I try to activate the others ussertts, launchpad shows the success message but into the text I use shift + sym to initialize the TTS but never begin. It's always "thinking-circle".
can you get the old tts voices?

Thanks,
DD
The TTS subsystem needs some time to reinitialize after switching, if it doesn't start reading give it few more seconds and then try to press shift+sym again.
You can rename the usertts folder and reboot your Kindle.
If you need to switch to the original voices frequently, use the attached usertts.ini file in Launchpad. In addition to the original five shortcuts I've added a new one for switching to the original voices (Tom & Samantha).

• SHIFT T O - Use original built-in voice data
