There are many voice cloning tools available, but the list of free and instant ones is quite short with some restrictions. Notable among the choices is DescriptandOverdub. Descript provides a free version of its voice impersonation tool and companies paid giving the possibility to clone user's own sound with reasonable accuracy. TechCrunch reported that as of 2023, Overdub had over 10,000 free users. Yet this free version has a limit on the number of voices you can clone and level of customization as opposed to its paid counterpart.
iSpeech on the other hand offers a free version of its voice cloning service In 2024, a review reminds us that iSpeech provides basic voice cloning at zero cost. It is free but limited to the number of voices you can clone each month so it's great for proof of concept or minimal example, less good if you want to go large scale (Paid versions exist too).
While it has a more limited selection in how many voice models can be cloned, and to what degree you may customize them — Resemble AI also offers a free tier. This plan may be subject to limitations compared their fully fledged paid offerings.
Voicery, another player in the game is providing free trials with certain basic voice cloning. They boast a free trial of the service that about 15% of their user base decides to tentatively test out prior to buying. This kind of free trial has some limited voice models and basic features for demonstration without money.
For example, in the case of users looking for instant voice cloning free, platforms such as DUPDUB let them immediately use all its available voice services without any charges. While these platforms typically feature immediate results, you may find yourself limited to the features of their paid siblings. The expedience and simplicity of DUPDUB enables it to still be useful as a fast solution for light voice cloning work at very little cost.
