导言
Voice-enabled products today require higher performance than ever before.
Applications such as AI assistants, smart robots, conference devices, and industrial voice terminals demand robust far-field voice capture, advanced noise reduction, and flexible system integration.
This raises a common engineering question:
Should developers choose a traditional microphone array platform such as the Andrea DA-252, or adopt a modern MEMS microphone array architecture?
Technical Comparison
