Give Your Chat Agent a Voice — Luke Harries, Head of Growth, ElevenLabs
Overview
This talk explores the evolution of chat agents, arguing that voice is the next natural and accessible interface, surpassing text-based interactions. It introduces Voice Engine, a product designed to easily integrate voice capabilities into existing chat agents, enabling richer, more interactive, and omni-channel experiences. The core thesis is that chat agents will either adopt voice or become obsolete, highlighting voice as a crucial upgrade for conversational AI.
Who should watch
- AI Engineers looking to add voice to their applications.
- Product Managers exploring new interaction paradigms for AI products.
- Builders seeking to enhance accessibility and interactivity of their agents.
- Developers who have already invested in building chat agents and want to add voice without a full rebuild.
- Those interested in the future of conversational AI beyond text interfaces.
Key takeaways
- 2025 was the year of chat agents, with many applications adopting a chat interface as the default.
- Voice offers a more natural, quicker, and accessible interaction medium compared to text, benefiting users with disabilities or those who struggle with keyboards.
- Adding voice unlocks new interaction paradigms, allowing agents to participate in calls, handle phone lines, and offer more dynamic engagement.
- Voice Engine is presented as a solution to wrap existing chat agents with voice capabilities, simplifying integration for developers who have already built complex agent logic.
- The Voice Engine combines advanced speech-to-text (Scribe) and text-to-speech (V3) models with emotion-aware turn-taking and semantic understanding.
- Developer experience is a key focus, with simple SDKs for both server-side integration and client-side widgets, enabling rapid conversion of chat agents to voice agents.
- Tool calling is handled by the existing chat agent's backend, meaning voice integration does not require rebuilding this functionality.
- The future of chat agents likely involves either the adoption of voice capabilities or a decline in relevance.
Notable quotes
