Hack #10: Speech Engine

Build something creative using ElevenLabs Speech Engine, then submit a high-quality viral-style video demonstrating what you've built.

Speech Engine adds voice capabilities to any chat agent. ElevenLabs handles speech-to-text and text-to-speech while your server provides the LLM logic. The SDK manages connection lifecycle, turn-taking, and interruption detection so you can focus on your agent's behavior.

What we're looking for

We want to see projects that push the boundaries of what's possible with voice-enabled agents. Show us creative applications that combine your own LLM logic with Speech Engine's voice capabilities.

Some ideas to get you started:

• Voice-powered assistants — bring your chat agent to life with natural conversation
• Interactive experiences — games, storytelling, or educational tools with voice interaction
• Accessibility applications — help people interact through voice instead of text
• Custom AI agents — use your own LLM while ElevenLabs handles the voice layer
