Artificial intelligence (AI) may have been dismissed as a fanciful imagination during its nascent years. But the technology has since developed into a juggernaut. Even those who initially opposed AI, citing reasons like its potential to render the human workforce redundant, have since embraced this transformative technology. And if recent projections are anything to go by, then AI will be an indispensable part of our daily lives in the not-so-distant future.
Content generation is among the many industries that have benefited immensely from artificial intelligence. There are numerous AI tools and software that let creatives generate content and then help to edit the output. We also have applications that play the reverse role – generating content from scratch and then inviting creatives to give it a human touch. Voice cloning is a noteworthy application of generative AI programs.
In this post, we look at the 10+ voice cloning tools in the market. But in the interest of those encountering this word for the first time, we’ll start from the beginning by highlighting what voice cloning entails.
Introducing Voice Cloning
Voice cloning, also known as voice synthesis, refers to technology that utilizes artificial intelligence, deep learning, and text-to-speech (TTS) to generate synthetic voices that resemble a person’s natural voice. It’s akin to creating a copy of the person you intend your script to sound like.
The voice cloning technology came as a blessing to content creators, game developers, and filmmakers. Using the right tool, you can create realistic voiceovers to go with your vlogs, computer games, or television documentaries. And the best part is that voices aren’t generally protected by copyright. So, you can clone any celebrity’s voice provided that you do not portray the voice as belonging to them to gain undue commercial advantage.
Now, you may stumble upon some publications using the terms “voice cloning/synthesis” and “voice generation” interchangeably. However, these phrases do not exactly denote the same thing.
Voice generation is a broad term that encompasses the random creation of human (sometimes even non-human) voices. The output may not necessarily resemble the voice of a specific person. On the other hand, voice cloning deals with synthesizing voices of real people. These may range from celebrities to politicians, movie characters, or even your own voice.
Based on the descriptions, it’s logical to infer that voice cloning is a special type of voice generation.
10+ Best AI Voice Cloning Tools

Pricing: Paid plans start from $89.00/month; a free trial available
Beyondwords is a voice cloning software that provides instant access to text-to-speech voices from some of the best TTS services, such as Google WaveNet, Microsoft Azure, and Amazon Polly. The tool combines the power of these speech-to-text synthesizers with its natural language processing (NLP) algorithms and publishing tools to create a voice that’s as realistic as possible.
Each time you prompt Beyondwords, the tool analyzes your text using NLP. It then converts the text into vocal synthesis markup language (SSML). There are more than 550 premium voices spread across over 140 different language locales.
Beyondwords is also one of the few voice synthesizers that give its users access to ethically created voices. That’s due to its collaboration with numerous voice actors who contribute their talent exclusively to its platform.
The app also integrates with many content management system (CMS) software for improved productivity.
2. Lyrebird AI
Pricing: Paid plans start from $12.00/month; a free version also available
Lyrebird AI by Descript provides a slew of media editing and synthesis features designed to automate your workflows and streamline the often-tedious content creation process. Voice cloning is one of its noteworthy offerings.
The platform has been around for slightly over five years. It was established by Alexandre de Brébisson, Jose Sotelo, and Kundan Kumar, former PhD students at the prestigious Montreal Institute for Learning Algorithms (MILA). The trio founded Lyrebird while working under Yoshua Bengio, who would later receive the Turing Prize in 2019 for his outstanding works in neural networks and deep learning.
One of Lyrebird founders’ primary motivations was to create a user-friendly voice cloning software. The app’s dashboard is clean and intuitive.
To use Lyrebird AI, you simply input a sample of your voice and train it to sound like you. You can then type or copy-paste the script you wish to generate voice for and the tool will do the rest. As you might expect, Lyrebird also has plenty of voices that you can readily deploy for your projects.

This gives the final output higher clarity and human touch. Besides, you can tweak the voice to portray the speaker as a child or cartoonish character.
And while Respeecher doesn’t have a free version, the service comes with a generous 3-day free trial. You can clone over 100 voices during the trial period.
