Application | On the Nuvoton OpenWrt platform, this project leverages the OpenAI Realtime API to implement a real-time, voice-interactive ChatGPT that supports both voice input and voice output, delivering a natural and smooth conversational experience. |
BSP Version | MA35D1 Series OpenWrt 22.03 |
Hardware | NuMaker-IoT-MA35D16F90 V2.4 |
This example code demonstrates how to build a real-time, voice-interactive conversation system on the Nuvoton OpenWrt embedded platform using Python and WebSocket technologies, integrated with OpenAI’s latest Realtime API. After a user speaks into a microphone, the device records and uploads the audio in real time. The OpenAI model then quickly generates a voice response, which is immediately played back by the system, making human-computer interaction more natural, fast, and intuitive.
This low-latency interaction capability enables embedded platforms to support applications such as intelligent voice assistants, voice-based customer service, and educational chatbots. Even on resource-constrained devices, leveraging cloud-based AI allows for a voice interaction experience comparable to that of high-end devices like smartphones.
This example code is developed based on the Nuvoton OpenWrt 22.03 environment. You must first set up the Nuvoton OpenWrt 22.03 development environment (https://github.com/OpenNuvoton/Nuvoton-OpenWrt-22.03) before running this example.
While this document uses the NuMaker-IoT-MA35D16F90 evaluation board as an example, the content applies to any evaluation board that supports Nuvoton OpenWrt 22.03 and can run Python smoothly, including the MA35D0, MA35D1, and MA35H0 series.
