Bluetooth Voice Remote Control Solution

Introduction

In the smart home era, Bluetooth voice remote controls are redefining user-device interaction. By simply speaking a command, users can effortlessly control complex operations—eliminating the tedious and inefficient experience of traditional infrared remotes during program searches.

01. Solution Overview

The Bluetooth voice remote sends an HID code to the smart TV or set-top box when the voice button is pressed, triggering voice recognition. The LED flashes or stays on during recording, and voice data is transmitted to the TV/box. Upon receiving the HID code, the device activates voice recognition software, converts speech to text, and performs actions like searching for programs or launching apps.
