Exceeded expectations
Easy to set up and the offline capability is a huge plus for privacy-focused projects. The Tianwen official licensing gives me confidence in long-term support.

Perfect for offline IoT projects
This module works exactly as described. The offline recognition is fast and accurate, even with a bit of background noise. Great for my smart home automation setup without needing cloud connectivity.

Fast response time
The latency is incredibly low. My lights turn on almost instantly when I speak the command. The build quality of the core board feels solid too.

Great for robotics
Using this for a voice-controlled robot arm. It handles multiple commands well. Would give 5 stars if the microphone sensitivity adjustment was a bit more granular in the software.

Good value, clear documentation
The Tianwen license ensures good compatibility. Documentation was easy to follow for integrating with my ESP32. Only minor issue was the pin spacing, but nothing a breadboard couldn't handle.

Reliable voice control
I've tested several modules, and the ASRPRO 2.0 stands out for its stability. It recognizes custom command sets very well after training. Highly recommended for developers.
Q: Is a microphone included with the development board?
A: The core board includes a footprint for an analog microphone, but the microphone component itself is sold separately to allow for flexible placement.
Q: Can I customize the voice commands myself?
A: Yes, you can define up to 150 custom offline commands using the provided configuration tools and software suite.
Q: What voltage should I supply to the VCC pin?
A: The module operates safely between 3.3V and 5V DC. We recommend 3.3V for optimal compatibility with most microcontrollers.
Q: Does it support English language recognition?
A: Yes, the firmware supports both Mandarin Chinese and English. You can switch languages via the configuration software.
Q: Does this module require an internet connection to function?
A: No, the ASRPRO 2.0 is designed specifically for offline voice recognition. All processing happens locally on the chip.
