Product Description

HW-US003 Offline speech recognition module


1.Product Overview
HW-US003 Our company's latest offline voice intelligent recognition module has a beautiful appearance, simple and compact product circuit structure, stable performance, affordable cost, and high cost-effectiveness. Especially suitable for secondary development in other electronic fields such as intelligent appliances, voice wake-up products, lighting products, etc.
This product can be widely used in intelligent voice, intelligent control systems, voice lighting products, smart home control unit products, and so on.
2. Working principle of the product:
HW-US003 is an intelligent voice controlled offline speech recognition module that does not require networking. It adopts an internal 32bit RS IC architecture and core computing logic. It collects and compiles text pronunciation through a microphone, accurately responds to customized wake-up words, outputs speaker voice broadcasts, and IO port signals. After speech acquisition and recognition, the output IO port signal can drive various circuits to work.
3.Product features:
3.1. This module has rich IO output protocols and supports various application products developed twice. The PCB structure is simple, and it supports self compiling wake-up unit words and customizing wake-up unit words.
3.2. Support the compilation of Chinese and English unit word protocols, and download SDK files online. It has precise speech recognition function with wake-up words and anti false alarm function.
3.3. Support repeated compilation and burning of CH340 downloader. Support multiple tone voice broadcasts, and support up to 150 unit vocabulary voice recognition broadcasts.
3.4. Supports up to 10 GPIO ports for dynamic output, 1 12C master-slave controller, and multiple PWM ports for output. 1 SDR-ADC signal collector, etc
3.5. Support SDK voice compilation, burning, and downloading.
3.6. Support time timing settings.
