Perfect for my smart lamp project
This module worked flawlessly out of the box. The offline recognition is surprisingly accurate even with background noise. Setup via UART was straightforward using the provided documentation.

Exceeded expectations
Very impressed with the sensitivity. I can whisper commands from across the room and it still picks them up. The development board layout makes prototyping easy.

Solid core module
Good build quality and stable firmware. The only reason for 4 stars is that the English voice pack needs a bit more tuning for heavy accents, but overall a great product.

Robust offline performance
I needed a solution that didn't rely on cloud connectivity, and this fits the bill perfectly. The latency is low, and the GPIO triggers are very reliable for controlling relays.

Great value, minor learning curve
The hardware quality is excellent for the price. It took me a little while to configure the custom command set, but once done, it responds instantly. Highly recommended for hobbyists.

Easy to start with
As someone new to voice modules, I found the tutorials helpful. Got my first voice-controlled fan running in under an hour. Will buy more for other projects.
Q: What is the maximum distance for effective voice pickup?
A: With a standard electret microphone, the effective range is typically 3 to 5 meters in a quiet environment. This can be improved with a higher gain microphone array.
Q: Does this require an internet connection to work?
A: No, this is a fully offline voice recognition module. All processing is done locally on the chip, ensuring privacy and zero latency due to network issues.
Q: Can I train this module to recognize specific custom phrases?
A: Yes, the ASRPRO 5.0 supports up to 500 customizable voice commands. You can configure these using the official PC configuration tool via USB-UART.
Q: Is there a library available for Arduino integration?
A: Yes, we provide sample code and libraries for Arduino, ESP32, and STM32. You can download them from the 'Downloads' section on our product wiki page.
Q: Can I power this directly from a 5V USB port?
A: Absolutely. The board includes an onboard LDO regulator that accepts input voltages between 3.3V and 5V, making it compatible with standard USB power sources.
