ESP32-Korvo AI Development Board Leverages ESP-Skainet Voice Assistant

Last September, Espressif Systems unveiled ESP-Skainet voice assistant optimized for ESP8266 and ESP32 wireless SoC with support for WakeNet wake word engine and MultiNet speech commands recognition with the former requiring just 20KB RAM for one word, and the latter supporting up to 100 offline commands as long as you had 4MP SPI flash or more. At the time, it only supported the Chinese language and worked on the upcoming “LyraT-Mini audio board“, now available for $26.99 shipped but only including one microphone. Espressif Systems has now announced a better AI development board with ESP32-Korvo AI development board includes featuring a mainboard with ESP32 processor and an audio ADC, and a subboard equipped with a 3-mic array, RGB LEDs, and various buttons. ESP32-Korvo specifications: Mainboard Wireless module – ESP32-WROVER-B with ESP32 dual-core Wi-Fi / BT processor, 128 Mbit SPI flash, and 64 Mbit PSRAM Storage – MicroSD card slot Audio […]

NXP i.MX 8M Mini Pico-ITX SBC Comes with Audio DSP, Optional PoE and Google Coral M.2 Module

We’ve covered several NXP i.MX 8M Mini SBC‘s since the announcement of the processor in 2018 as the first i.MX SoC manufactured with a 14nm process allowing for a higher CPU clock of 2.0 GHz compared to the 1.5 GHz frequency used with the original i.MX 8M processor. i.MX 8M Mini also removes some features (4K video playback, some video interfaces, …) in order to lower the cost of the processor. Companies are still releasing new i.MX 8M SBCs regularly, but we don’t always cover them all since many often do not offer much compared to the competition. But Estone Technology EMB-2237-AI Pico-ITX SBC has some unusual features and options including a Cirrus Logic audio DSP, as well as support for a PoE module and Google Coral M.2 AI accelerator module. EMB-2237-AI SBC is comprised of a system-on-module and baseboard with the following specifications: Estone SOM-2237 module SoC – […]

Amlogic A113L Dual-Core Cortex-A35 Processor Targets Smart Audio and IoT Applications

Over two years ago, we reported about Amlogic A111, A112, A113 processors designed for audio applications such as smart speakers. A111 features four Cortex-A5 32-bit core, while A112 and A113D/A113X processors come with four Cortex-A53 cores instead. We have not heard much about those since then, but all those processors are still listed on Amlogic website, A112 is supposedly used in Xiaomi AI smart speaker, and Amlogic A113X1 Far-Field Dev Kit is still listed on Amazon’s list of devkits for Alexa voice service, but currently out of stock. Amlogic has been working on a more cost-efficient processor for smart audio and IoT applications with Amlogic A113L dual-core Cortex-A35 processor shown as Meson A1 in the Linux source code. It was just added in Linux 5.5. We don’t have much information about it, but it’s interesting as it’s the first Cortex-A35 processor from the company, and it targets the same smart […]

Bluetooth LE Audio Supports LC3 Codec, Multi-stream & Broadcast Audio, Nordic Semi Evaluation Kit Unveiled

I first heard about Bluetooth LE (Low Energy)- part of Bluetooth 4.0- in 2013 with RFDuino board, and it came to prominence once Android 4.3 added support later this year. Bluetooth LE is using to transmit messages using as little as energy as possible for example to synchronize data between a smartphone and a smartwatch. But if you ever had to transmit audio, you had to rely on Bluetooth Classic which, albeit considering low power, consumes more energy. But you should soon have much longer battery life on your Bluetooth headphone or battery-operated speaker, as the Bluetooth SIG has just announced Bluetooth LE Audio which adds a new codec and support for multi-stream and broadcast audio. The new high-quality, low-power audio codec used in the new Bluetooth standard is called the Low Complexity Communications Codec (LC3). The chart above shows the results of listening tests between LC3 and SBC codecs […]
