The Elechouse Voice Recognition Module V3.1 is a highly integrated, low-cost hardware solution designed for speaker-dependent speech processing . It operates entirely offline without an internet connection. This makes it a popular choice for embedding local voice control into robotics, smart home automation, and internet of things (IoT) devices. The board acts as an acoustic pattern matcher. Users train the module by recording distinct voice commands directly into its onboard flash storage. When a matching phrase is spoken, the board transmits a corresponding hex command or triggers logic pins to execute specific hardware actions. Technical Specifications and Pinout The physical board is compact ( ) and runs efficiently on standard logic levels. Hardware Specifications Voice Recognition Module - 254 Voice Commands + UART

Voice Recognition v3.1 – Smarter, Faster, More Intuitive We’re excited to introduce Voice Recognition v3.1 , a major step forward in accuracy, responsiveness, and real-world usability. Whether you're dictating documents, controlling smart devices, or navigating hands-free, v3.1 delivers a seamless voice experience. What’s New in v3.1
Enhanced Accuracy in Noisy Environments Advanced noise filtering and echo cancellation reduce errors by over 30% in crowded or moving settings (e.g., cars, open offices, public transit). voice recognition v3.1
Lower Latency, Real-Time Processing Optimized neural engines cut response time to under 200ms, making conversations with your device feel truly natural.
Improved Speaker Diarization v3.1 can distinguish between up to six different speakers in a conversation, labeling each speaker (Speaker A, B, etc.) with 95% accuracy.
Expanded Language & Dialect Support Added support for 12 new languages and regional dialects, including Swiss German, Brazilian Portuguese, and Cantonese. The Elechouse Voice Recognition Module V3
On-Device + Hybrid Mode Choose between fully local processing (for privacy) or hybrid cloud-enhanced mode (for maximum vocabulary and context understanding). Switching is seamless.
Adaptive Voice Profiles The system now learns your pronunciation, common phrases, and speaking pace over time — no manual training required.
How It Works (Simplified)
Wake word detection – Trigger phrase recognition with ultra-low false accepts. Front-end processing – Noise reduction and echo cancellation. Speech-to-text engine – Transformer-based acoustic and language models. Intent & context analysis – Understands commands, dictation, and conversational queries. Response & action – Executes command or returns transcribed text.
