Several companies are already offering development kits for Amazon AVS (Alexa Voice Service), but as we’ve seen in the past, those are rather expensive with far-field kits such starting at $349 with kits such as Synaptics AudioSmart 4-Mic Development Kit, or Intel Speech Enabling Developer Kit, and hands-free kits being barely cheaper at $299 and up. But there will soon be a cheaper solution, as Allwinner and SinoVoIP (aka Banana Pi) are working on “SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS” that includes 3 microphones, and works without special DSP, relying instead on Allwinner R18 processor’s audio codec and capabilities. Allwinner SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS (aka R18-AVS-EVK) specifications: SoC – Allwinner R18 quad-core Cortex-A53 processor @ 1.15GHz with Mali400MP2 GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash Video Output – HDMI Audio – 6x Microphones, 2x AEC, AUX and headphone output; GMEMS voice […]
$17 Sonoff S31 Wireless Smart Socket Includes Energy Monitoring Function
ITEAD Studio has just launched another Sonoff Smart Home product with Sonoff S31 WiFi smart socket with energy monitoring. Just like Sonoff switches, light bulbs, and their other products, the device can be controlled using eWelink app for Android or iOS, and supports integration with Amazon Alexa, and Google Assistant. It should be noted that the company only provide a US plug version for now, and so far, there’s no Wiki link, so while it’s likely based on ESP8266 or ESP8285 like their other Sonoff devices, it may not be designed to be easily hackable, although I suspect the electronics may be similar to Sonoff POW switch (TBC). Sonoff S31 hardware specifications listed by ITEAD: Voltage Input – 90~264V AC, 50/60HZ Max. Current – 16A Max. Power – 4200W (Note package above reads max load: 220V/10A) Gang – 1x US type with ground Connectivity – 802.11 b/g/n WiFi with support […]
Intel Speech Enabling Developer Kit Works with Alexa Voice Service, Raspberry Pi 3 Board
We’ve known Intel has been working on Quark S1000 “Sue Creek” processor for voice recognition for several months. S1000 SoC is based on two Tensilica LX6 with HiFi3 DSP, some speech recognition accelerators, and up to 8x microphones interfaces which allows it to perform speech recognition locally. The solution can also be hooked to an application processor via SPI, I2S and USB (optional) when cloud based voice recognition is needed. Intel has recently introduced their Speech Enabling Developer Kit working with Amazon Alexa Voice Service (AVS) featuring a “dual DSP with inference engine” – which must be Quark S1000 – and an 8-mic array. The kit also includes a 40-pin cable to connect to the Raspberry Pi 3 board. Intel only provided basic specifications for the kit: Intel’s dual DSP with inference engine Intel 8-mic circular array High-performance algorithms for acoustic echo cancellation, noise reduction, beamforming and custom wake word […]

Review of Vobot Alarm Clock with Alexa
Karl here with a review of Vobot sent By Cafago. I had to Google it when I was asked to review it. Turned out it was an Echo type device with a pixel display and a battery. It started as an Indiegogo campaign. I had been wanting to try to do some sort of voice control with my home automation so I agreed to review it. Vobot Clock C1 Specifications These are pulled from Vobot’s website. No power supply is included but a long USB cable is. Vobot Setup I let my wife do the initial setup as I figured that she would use it the most. She followed the instructions, and it seemed straightforward from what she told me. She said she had to reboot it once during a step but it continued the setup with no problems. She tied to our Amazon Prime account, and she quickly was […]
Sonoff B1 is an $18 Hackable WiFi RGB LED E27 Light Bulb based on ESP8285 WiSoC
Earlier this year, I wrote about an ESP8266 based RGB LED “AI Light” lightbulb that was hacked to run ESPurna open source firmware. That’s all good, except some people tried to get one, and ended with a different hardware. So if you’d like something that’s more of a “sure thing”, ITEAD Studio has designed Sonoff B1 dimmable RGB LED E27 light bulb based on ESP8285 processor, and with a “4 pads” to allow for custom firmware flashing. Sonoff B1 hardware specifications: Typical Lumen Output – 600lm Beam Angle – 120 degrees typ.
