Elevate your TinyML Projects with Arduino Nicla Voice Featuring Syntiant NDP120

In a world where voice assistants can be activated by just a simple activation voice command line like “Ok Google” or “Alexa”, the importance of vocal input is crucial. Nicla Voice is a development board designed to help developers create and deploy machine learning models on edge devices, specifically for voice applications. Powered by the Syntiant NDP120, a neural decision processor, the boards can handle AI algorithms, speech recognition, and natural language processing seamlessly. With its low-power microcontroller, the board is well-suited for building and testing a wide range of voice-controlled devices like smart speakers, voice assistants, and other tinyML projects.

Technical Specifications of Nicla Voice

• The Nicla Voice uses Syntiant NDP120 Neural Decision Processor which uses 1x Syntiant Core which is an ultra-low power deep neural network interference engine; 1x Hi-Fi Audio digital signal processor(DSP) and 1x Arm Cortex M0 core which works at 48MHz.
• The board also features nRF52832 which is a general-purpose multiprotocol SoC. It is packed with Arm Cortex-M4 running at 64 MHz, 512/256 KB Flash, 64/32 KB RAM and Bluetooth 5.3(BLE).
• The sensors used are IM69D130 which is a high-performance microphone. Board also features BMI270 which is a 6-Axis IMU and a 3-axis magnetometer BMM150
• The Nicla Voice is just 22.86 x 22.86 mm and weighs just 2g. The module has an operating temperature range of 0° C to +70° C.

The Syntiant NDP120 is a special-purpose processor for deep learning and is ideal for always-on applications in battery-powered devices. It is built using Synthia Core 2 programmable deep learning architecture. Core 2 delivers 25 times better performance than its predecessor Synthia Core 1. It’s designed to run deep neural networks on various architectures natively.
