In the ancient land of Eldoria, where skies shimmered and forests, whispered secrets to the wind, lived a dragon named Zephyros. [sarcastically] Not the “burn it all down” kind... [giggles] but he was gentle, wise, with eyes like old stars. [whispers] Even the birds fell silent when he passed.

As a scientist and educator, I've always believed that the best scientific and health information should be accessible to everyone—not just English speakers. That's why I'm excited to share that we're working with @elevenlabsio to begin exploring dubbing of Huberman Lab content,… pic.twitter.com/QHZv4Inyro

Text-to-speech (TTS) is a technology that converts written text into spoken words using artificial intelligence (AI) and deep learning. It enables computers, apps, and websites to generate human-like speech, making digital content more accessible and engaging for people who want to have their content read aloud.
TTS works by analyzing text input and converting it into phonetic representations, which are then processed by speech synthesis models. Early TTS systems sounded robotic because they relied on pre-recorded speech units. However, modern AI-driven text to speech generators, like ElevenLabs, use neural networks and deep learning models to create natural-sounding AI voices with intonation, emotion, and context awareness.
The key components of a TTS system include:
• Text processing: Breaking down input text into words, phonemes, and linguistic units.
• Prosody modeling: Determining speech rhythm, intonation, and pitch to ensure natural flow.
• Voice synthesis: Generating realistic AI voices by mimicking human speech patterns.
TTS technology is used in a wide range of applications, including:
• Accessibility tools for visually impaired users (screen readers, audiobooks).
• AI voiceovers for YouTube videos, podcasts, and commercials.
• E-learning and training modules to provide engaging narration.
• AI assistants & chatbots that offer human-like interactions.
ElevenLabs AI text to speech takes this to the next level by producing highly realistic voices in 70+ languages, supporting emotional speech synthesis for more natural conversations.
ElevenLabs voice AI combines proprietary methods for context awareness and high compression to deliver ultra-realistic, high-quality speech across a range of emotions. Our contextual text to speech model is built to understand the relationships between words and adjusts delivery accordingly. It also has no hardcoded features, meaning it can dynamically predict thousands of voice characteristics
ElevenLabs supports 70+ languages with high-quality accent rendering. Polly supports 29 languages with fewer accent variations.
ElevenLabs offers simpler, per-character pricing. Polly uses a per-million character model with varying costs per voice.
Yes, ElevenLabs provides commercial usage rights in all paid tiers.
Only with ElevenLabs. Use Voice Design to generate voices from text prompts.
