| Memory | 4 GB (8 GB recommended) |

Free trial and free mode
After installing, every feature is unlocked for 7 days. No payment details are asked. When the trial ends the app keeps working in free mode, with limits on each feature. Buying a licence removes the limits.
Buying and activating a licence
- Choose a plan on the pricing section and pay.
- Your activation code appears on screen and is also emailed to you.
- In the app, open the Activate screen, enter the code, and confirm. Your PC needs internet for this step.
One licence works on one PC. If you buy a new PC or reinstall Windows, contact support and we will move the licence.
Voice quality levels
- Natural: studio-quality voices in English and several other languages. Included.
- Fast: light Marathi and Hindi voices, male and female, that run on any PC. Included.
- Ultra: the most human-like Marathi, Hindi and Indian English voices, with emotions. An optional Voice Pack; best with 8 GB of memory or an NVIDIA card.
Voice Packs
Voice Packs are optional downloads that add voices and tools such as Ultra voices, speech recognition, translation and the voice enhancer. Open the Voice Packs page in the app and click Download. Downloads can be paused and resumed, and a pack can also be installed from a file on a PC without internet.
Common questions
Does it work without internet?
Yes. Speech is created on your PC. Internet is needed only to activate a licence, to download Voice Packs, and from time to time to confirm the licence.
A voice is slow on my PC. What can I do?
Use Natural or Fast voices, which are quick on any PC. Ultra voices and voice cloning do much more work; they are faster on a newer processor or with an NVIDIA card.
I did not get my activation code.
Check your spam folder first. If it is not there, write to us through the support form with the email address you paid with and your payment ID.
Can I clone any voice?
Only your own voice, or a voice whose owner has given you permission. See the Terms of service.
