Features
1. 100% brand new and high-quality products.
2. Made of high-quality materials, durable and practical.
3. ReSpeaker 4-Mic Array for Raspberry Pi is a 4-microphone expansion board for Raspberry Pi, specially designed for AI and voice applications. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa voice services, Google Assistant, and more.
4. ReSpeaker is an open modular voice interface that can crack things around you. Allows you to interact with household appliances, factories, offices, Internet-equipped devices or anything else in daily life through voice. The ReSpeaker project provides hardware components and software libraries to build voice-enabled devices.
5. Unlike ReSpeaker 2-Mics Pi HAT, this board is developed based on AC108, which is a highly integrated four-channel ADC with I2S/TDM output conversion for high-definition voice capture. In addition, this 4-Mics version provides a super cool LED ring, which contains 12 APA102 programmable LEDs. With those 4 microphones and LED ring, Raspberry Pi will be able to perform VAD (Voice Activity Detection), estimate DOA (Direction of Arrival) and display the direction through the LED ring, just like Amazon Echo or Google Home.
