Now there are some necessary things that you need if want to use free voice cloning online. The obvious one is that the users need an audio sample in respect to their voice they want cloned. Usually this means capturing at least 10 to 20 minutes worth of speech, but some platforms will allow shorter samples with accuracy. This means that the widely used, free TTS system available from Mozilla for training a text-to-speech model may require on the order of 15 minutes or more of clean audio to form at least an operational voice.
A high-speed internet connection is the most important thing to have, because you will upload (large) audio files to our server. A typical voice recording file size is between 10 megabytes to 50 MB, depending on the length and quality of it. A good internet connection guarantees steady data transfer preventing any interruptions that may hinder the cloning.
In this way, users should also agree to use the user-friendly interfaces or tools offered by these free providers. Web interfaceYou will find free voice cloning online platforms like this to have a simple web interface, which instructs the user on how they could upload their audio and customize their voice models. But these tools may also lack the breadth of features and customization available from their for-pay siblings.
The cons: free tools often require you to register or create an account, which usually means providing some email address. Some folks really dislike this and may feel repelled by your call-to-action right away. The feature set is pretty standard and while it comes at no charge, users should expect to trade away privacy instead: their information might be collected for marketing purposes or service improvement. For example, on the Respeecher website user accounts are often needed to keep a record of how much you use it and also so voice models can be managed.
Apart from the fundamental requisites, one needs to seriously think about production; It means quality of your audio recording equipment. Better voice cloning requires using high quality microphones and recording in quiet environments. A great microphone will run you between 50 and $200, with a quiet place to record removing background noise that would obscure the clarity of your audio sample.
In general, a fully free online voice cloning solution demands clear input samples (like real-time recordings), good internet speed, easy-to-use platform or equipment and hopefully just minimal investment.
