Ai Voice Cloning : How does it Work and Where is it Used?

What is voice cloning?

Voice cloning is the name of the process that allows artificial intelligence to create a cloned or copied version of a natural human voice.

When done well, the natural and synthetic voices are confusingly similar. Often this cloning model is applied to voices for text-to-speech technologies.

More commonly known is the term voice cloning as “Deepfake voice”.

How exactly does cloning a voice with AI work?

When a speaker wants to clone his voice synthetically, he must first record a large amount of audio material. This is used to create a dataset of all the nuances of his voice. Certain audio specialists develop the cloned voice through a network of virtual neuron connections. The process takes a lot of time and effort – yet the results are baffing.

Step 1 – speaker selection

The central component is an extensive collection of audio samples of human speech, and it is important that these audio recordings are of high quality. We recommend choosing a speaker who has experience with this type of recording and having the recordings done by a sound engineer with professional equipment.

Have in mind that the target group likes the selected voice and speaking style – it will represent your company.

Step 2 – transcript creation

As said the cloning model often is applied to voices for text-to-speech technologie. In this case the transcript is the written part and necessary for the voice cloning. A transcript is a collection of sentences and utterances that must be spoken by the speaker.

If you produce a voice clone with BotTalk, we will take care of the transcript based on your content.

Step 3 – recordings

Each audio file should contain a single sentence, which is delivered in the transcript. All files must be in the same spoken language and style. We recommend defining a speaker persona beforehand. This document defines elements such as the characteristics of the voice and the character behind the voice. This helps to guide the process of creating a voice clone and your expected result. Important is that the recordings must match the corresponding transcript by 100%. Errors in the transcripts will lead to loss of quality during the training.

Step 4 – processing

When the data set of the transcript and recordings are ready, the processing can begin. Audio specialists will process through a neural network and create a voice clone. After every iteration, you will receive a voice sample to review the quality of the voice. If the quality is too low, you provide fewer voice data, and the audio specialist team will need further recordings. Through this process, they can directly participate in the development and follow the training of the voice clone.

Where is voice cloning used today?

Film & Television Industry

The voices of actors can be synthesized to facilitate the work of productions. Primarily when an actor records audio for marketing and advertising purposes, their voice clone can be used much more widely. This process saves time and costs and allows the possibility to use that voice in 10 years.

In the last Star Wars movie, the film editors had to painstakingly recreate the character of General Leia Organa after actress Carrie Fisher died during filming.

Imagine how much easier this would be with voice cloning.

Publishiers & News

At BotTalk we produce voice clones for radio stations and publishers.

Our goal is, on the one hand, to develop new voices for accents and dialects that do not exist on the market. On the other hand, to make it possible for publishers or authors to establish a unique brand AI-voice to promote digital content further.

With voice cloning the editorial team can read aloud every single article in your local newspaper. The synthetic voice will sound much more familiar to the listener than a standard synthetic voice. A similar use case is applicable for radio stations to read aloud the weather forecast or traffic information by a synthetic voice.

Education

Voice clones are often used to make life easier for online educators..Their voices can be synthesized to facilitate the work of productions. Once enough audio material is available, the professor can further dub his videos with the help of TTS (and the voice clone) with little effort.
