TypeScript Case Study

Speak Well

A tool for learning languages using AI and the ElevenLabs API.

Case Study: Speak Well

Speak Well was born from the need to practice conversational skills in a foreign language without the pressure of a human tutor.

The Challenge

Learning a language requires immersion, but finding native speakers for consistent practice can be difficult and expensive.

The Solution

By integrating the ElevenLabs API for high-quality text-to-speech and OpenAI’s GPT-4 for natural conversation flow, I built an interactive interface that listens to users and responds in real-time.

Key Features

  • Voice Synthesis: Ultra-realistic voice output.
  • Natural Conversations: Context-aware responses.
  • Interactive Learning: Instant corrections and grammar suggestions.
