What is ElevenLabs (Elevenlabs.io)? 

“We’re building cutting-edge technology to make content accessible across languages — and voices — to enable everyone to connect with information and stories that matter.” — Mateusz Staniszewski, CEO of Elevenlabs

‍

Founded in 2022 by childhood best friends Piotr Dąbkowski and Mateusz Staniszewski, ElevenLabs has quickly gained over a million users. The company is known for its text-to-speech (TTS) technology that instantly converts text to natural AI voices in 29 languages. Elevenlabs’s unique features include:

• Movie Dubbing Tool: This lets you dub entire movies, and edit transcripts, translations, and timing.
• Voice Library Marketplace: Create and share AI versions of your voice. Earn money when others use your voice, with full control over its use.
• Mobile App Reader: Turns text and web pages into audio so you can listen on the go. 
• Expanded AI Dubbing: Automatically translates videos into 29 languages, keeping the original voice and emotions.
• Voice Transformation: Changes one voice to another while keeping its unique traits.

How Does ElevenLabs Work? 

ElevenLabs uses machine learning techniques to create high-quality synthetic voices. At the core of their technology are deep learning models like Generative Adversarial Networks (GANs) and Transformer architectures. These models are trained on extensive datasets of human speech, learning the nuances of intonation, pitch, and rhythm to produce natural-sounding audio.

When you use ElevenLabs, the system converts your textual input into realistic spoken language through techniques like feature extraction and neural vocoding, which help capture the unique characteristics of human speech.

The model's architecture includes multiple layers of neural networks. This allows it to understand and replicate the complex patterns found in natural speech, ensuring that the voices you hear are “indistinguishable” from human voices. 

ElevenLabs Pricing

ElevenLabs offers six pricing tiers, including a free plan. If you want to use ElevenLabs for free, you can generate up to 10,000 characters per month, create up to 3 custom voices, and access shared voices in the Voice Library. However, this plan does not include a commercial license.
