15.AI: Everything You Need to Know & Best Alternatives

Delve into the wierd and wacky world of 15.ai and discover the top alternatives to 15.ai for 2024.

When 15.ai sprung onto the scene in 2020 with its AI text-to-speech technology, it became a one-stop shop for voice clones of all your favorite real-life and fictional characters.

Developed by an anonymous MIT researcher under the name '15', this platform became the go-to text-to-speech tool for anyone who wanted to create lifelike and realistic AI voices for any reason. Yet, 15.ai is no longer available, and issues of copyright, competition, and more have meant that 15.ai is not likely to return online any time soon.

This blog will tell the story of 15.ai. We'll learn how 15.ai began, what it is, and the best 15.ai alternatives on the market so you can start using the latest in artificial intelligence to create your own voiceovers.

What is 15.ai?

15.ai was launched in 2020 as a text-to-speech converter platform that allowed creators to convert text into natural speech using the power of artificial intelligence. Combining speech synthesis with machine learning, deep learning, deep neural networks, and audio synthesis algorithms, 15.ai transformed how users created different voices with AI text.

The freeware site could create voices in real time using sentiment analysis models, providing you with a high-quality voiceover immediately to generate emotional and realistic voices as fast as could be. On September 8, 2022, 15.ai was taken down, citing a new update was coming, but as of January 2024, it is still offline.

What Does 15.ai And Its Alternatives Do?

As 15.ai is currently offline, we have to go back in time to describe what exactly 15.ai alternatives do and what they can be used for.

Generates Expressive Character Voices

AI text-to-speech software can create voices from a catalog of media sources and speech synthesis without the need to hire voice actors for your projects. Unscrupulous software even allows you to clone celebrity voices like Barack Obama and Donald Trump, which raises ethical questions about their right to privacy, copyright infringement, and more.

Converting Text Into Different Languages

The internet contains a huge wealth of videos and content, but the majority of it is in English. For many people, having an alternative translation of the content they enjoy in another language is a better way to engage with their favorite creators.

AI gives creators the power to translate their content into multiple languages, reaching a wider audience and improving engagement rates.

Create Natural Sounding Voices

If you have a particular project or story you want to tell in mind, you'll need your characters and their AI voices to sound just right. This might mean using a male or female voice, choosing a specific localized accent, or even speaking at a certain tone or pitch.

All this is easy to do with AI technology. In just a few clicks, a content creator can turn their script into narration from a wise old British man and then into speech that sounds like a young American woman. That means no lengthy interview processes for the perfect voice actor and fewer costs involved in your content creation.

The Best 15.ai Alternatives

There are dozens of 15 AI alternatives out there, but only a few truly get the job done.
