The ElevenLabs Voice AI Hackathon, held in collaboration with lablab.ai from July 28th to 31st, invited creatives and tech enthusiasts to develop applications using ElevenLabs' voice AI models, such as Text to Speech and Voice Cloning, for diverse purposes like content creation, accessibility, and gaming. Participants could incorporate additional AI models, provided they didn't directly compete with ElevenLabs' technology, to enhance their projects and explore applications like AI companions, video dubbing, and assistive tools. The event offered free access to the ElevenLabs platform, mentorship, and networking opportunities, while finalists presented their solutions on August 7th for a chance to win cash prizes and entry into the Slingshot Early Stage Accelerator program.
