Powering world’s leading companies and brands
“From dubbing Reels in local languages, to generating music and character voices in Horizon, ElevenLabs platform enables global creators, businesses, and enterprises to build with voice, music, and sound at scale.”
“Millions of people learn chess from creators like Hikaru, Levy, and Magnus every day on YouTube and Twitch. Now you can learn from them inside Chess.com in a way that feels immersive, personal, and full of character. Our mission is to build a chess coach that teaches at the right level, welcomes players of every skill level, and demystifies chess while keeping it fun and full of personality. With ElevenLabs and these amazing new voices, we’ve taken a big step toward making that vision a reality.”
“ElevenLabs made it easy for us to quickly bring powerful text-to-speech capabilities to our SDK, allowing Agents to respond in real time with expressive voices to user questions or as feedback to what it’s seeing.”

“Twilio has integrated ElevenLabs’ generative AI voice technology into its CPaaS, enhancing ConversationRelay. This integration allows businesses and developers to create conversational AI voice interactions that sound human, feel expressive, and respond in real time directly from the Twilio CPaaS platform. We at ElevenLabs are excited that Twilio has chosen ElevenLabs to enhance ConversationRelay with the most expressive, human sounding voices available. ”
