It is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command. - It has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized. - We already know that Voice Recognition module V2 supports 15 commands in all and only 5 commands at the same time. On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at the same time. On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. - Parameters: Voltage: 4.5-5.5V, Current: <40mA, Digital Interface: 5V TTL level for UART interface and GPIO, Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface. Size: 31mm x 50mm. Recognition accuracy: 99% (under ideal environment). - Features: Support maximum 80 voice commands, with each voice 1500ms (one or two words speaking). Maximum 7 voice commands effective at same time. Arduino library is supplied. Easy Control: UART/GPIO. User-control General Pin Output. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Luxtech | | Manufacturer reference | LUXTECH-04-COMPONENT | | Manufacturer | Luxtech | | Series | V3 | | Form Factor | compact | | Computer Memory Type | DDR4 SDRAM | | Are Batteries Included | No | | Guaranteed software updates until | unknown | ## Product Details - **Brand:** Luxtech - **Memory slots available:** 1 - **Personal computer design type:** Barebone - **Model name:** V3 - **Special feature:** Compact - **Connectivity technology:** 3.5mm audio - **Human interface input:** Microphone ## Images ![Speech Recognition Module ELECHOUSE Voice Recognition V3 interface 5V TTL Level UART/GPIO - Image 1](https://m.media-amazon.com/images/I/41iJIakaO7L.jpg) ![Speech Recognition Module ELECHOUSE Voice Recognition V3 interface 5V TTL Level UART/GPIO - Image 2](https://m.media-amazon.com/images/I/51UB-x9gpwL.jpg) ![Speech Recognition Module ELECHOUSE Voice Recognition V3 interface 5V TTL Level UART/GPIO - Image 3](https://m.media-amazon.com/images/I/41CWNvCwIWL.jpg) ![Speech Recognition Module ELECHOUSE Voice Recognition V3 interface 5V TTL Level UART/GPIO - Image 4](https://m.media-amazon.com/images/I/41iJIakaO7L.jpg) ## Frequently Bought Together - Speech Recognition Module ELECHOUSE Voice Recognition V3 interface 5V TTL Level UART/GPIO - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - AZDelivery ESP32-DevKitC NodeMCU WiFi WLAN CP2102 ESP32-WROOM-32D IoT 2-In-1 Microcontroller Bluetooth Module Development Board compatible with Arduino including E-Book! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/111971881-speech-recognition-module-elechouse-voice-recognition-v3-interface-5v-ttl](https://www.desertcart.be/products/111971881-speech-recognition-module-elechouse-voice-recognition-v3-interface-5v-ttl) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-29*
