The blog post outlines how to build an AI voice assistant app named Pulse using ElevenLabs, Neon, and Next.js. ElevenLabs is highlighted as the core technology for generating natural, human-like speech through its AI voice synthesis platform, offering API-first integration and versatile speech capabilities. Neon, a serverless Postgres database, provides persistent data storage, ensuring the app can expand over time, while Next.js is used for both the front-end and back-end, facilitating user interface design, API requests, and real-time updates. The guide offers a detailed walkthrough for creating a similar app, with additional resources like a GitHub repository and community support via Discord, alongside special offers from ElevenLabs for AI developer tools.
