Voice Recognition V3.1 -

Elechouse Voice Recognition Module V3.1 is a compact, speaker-dependent board designed for offline voice control in electronics projects. It allows you to train specific vocal commands to trigger digital outputs on microcontrollers like Core Technical Specifications Storage Capacity : Can store up to 80 voice records in its internal memory. Active Commands : Recognizes a maximum of 7 voice commands simultaneously. Speaker Dependent

C. Expanded Language Models

• Dialect Support: Added specific acoustic models for regional dialects previously unsupported in v3.0 (e.g., distinct recognition patterns for Scottish English, Andalusian Spanish, and Quebecois French).
• Vocabulary Expansion: The offline command dictionary has been expanded by 20%, allowing for more complex local commands without cloud connectivity.

Assistive Tech

: Controlling wheelchairs or home appliances for users who need hands-free local control. voice recognition v3.1

: Since it is speaker-dependent, it often fails if there is significant background noise that wasn't present during the initial training phase. Limited Active Memory Elechouse Voice Recognition Module V3

• Wake-Up Time: The average time to detect the wake word has been reduced from 250ms (v3.0) to 150ms (v3.1), creating a more responsive "instant-on" user experience.
• False Rejection Rate (FRR): FRR has been lowered by 15% through the implementation of new anti-spamming logic.

Users currently running v3.0 can perform an Over-The-Air (OTA) delta update. The patch size is approximately 15MB. Dialect Support: Added specific acoustic models for regional
