ChatGPT Voice-Powered Chatbot Build with React and FastAPI

Packt brings React and FastAPI together around a voice-powered chatbot. Environment setup, backend functions, audio features and AI integration connect the user interface with external services. It suits developers who want to trace the full path of a conversation request and understand which work belongs in the browser, API or AI service, rather than view the chatbot as a single prompt.

What you will learn

• Connect a React interface with a FastAPI backend.
• Explore audio and conversational AI integration.
• Review prompts, environment setup and chatbot behavior.

Who this suits

Intermediate learners with JavaScript and React knowledge plus familiarity with frontends, backends, REST APIs and HTTP. Check separate AI API costs and current model availability before following the examples.

Before you enroll

Work in a local development environment with fictional records and keep API keys outside source control. Match the demonstrated Python, Pydantic and database-library versions with your project before copying code. Hosting, databases and AI services may cost extra. A completed course project still needs tests, access controls and an operational review before real users or sensitive information depend on it.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Build a local voice-chat prototype using a harmless fictional persona. Trace its audio and text requests, define a failure message for an unavailable service and keep credentials entirely outside browser-delivered code.
