Many years ago, when the first Bluetooth headset started to be sold, it was always a bit funny to hear people apparently talking to themselves while walking in the street. But soon enough, fellow walking zombies may start talking even more on the go, as Google and its partners have launched a new category of headphones with support for Google Assistant starting with Bose QuietComfort 35 II (aka QC35 II). The new headphones are actually an update to QC35 headphones that not only adds Google Assistant support but also noise control settings. It’s not really as cool as it first sounds though. The headphones have an “Action” button to trigger Google Assistant, so no “OK Google” or “Hey Google”, and support is not exactly built-in, meaning you’ll still need to pair the headphones with your smartphone over Bluetooth. You’ll then be able to hear your incoming messages and calendar automatically […]
Imagination Announces PowerVR Series2NX Neural Network Accelerator (NNA), and PowerVR Series9XE and 9XM GPUs
Imagination Technologies has just made two announcements: one for their PowerVR Series2NX neural network accelerator, and the other for the new high-end GPU families: PowerVR Series9XE and 9XM. PowerVR Series2NX neural network accelerator The companies claims 2NX can deliver twice the performance and half the bandwidth of nearest competitor, and it’s the first dedicated hardware solution with flexible bit-depth support from 16-bit down to 4-bit. Key benefits of their solution (based on market data available in August 2017 from a variety of sources) include: Highest inference/mW IP cores to deliver the lowest power consumption Highest inference/mm2 IP cores to enable the most cost-effective solutions Lowest bandwidth solution with support for fully flexible bit depth for weights and data including low bandwidth modes down to 4-bit 2048 MACs/cycle in a single core, with the ability to go to higher levels with multi core The PowerVR 2NX NNA is expected to be […]
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 […]
Arm Research Summit 2017 Streamed Live on September 11-13
The Arm Research Summit is “an academic summit to discuss future trends and disruptive technologies across all sectors of computing”, with the second edition of the even taking place now in Cambridge, UK until September 13, 2017. The Agenda includes various subjects such as architecture and memory, IoT, HPC, computer vision, machine learning, security, servers, biotechnology and others. You can find the full detailed schedule for each day on Arm website, and the good news is that the talks are streamed live in YouTube, so you can follow the talks that interest you from the comfort of your home/office. Note that you can switch between rooms in the stream above by clicking on <-> icon. Audio volume is a little low… Thanks to Nobe for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting […]
Amlogic A111, A112 & A113 Processors are Designed for Audio Applications, Smart Speakers
Amlogic processors are mostly found in TVs and TV boxes, but the company is now apparently entering a new market with A111, A112, and A113 audio processors. I was first made aware of those new processors through Buildroot OpenLinux Release Notes V20170831.pdf document posted on their Open Linux website, where two boards with Amlogic A113D and A113X are shown. First, S400 board with the following key features/specifications: SoC – Amlogic A113D CPU System Memory – 1GB DDR3 Storage – 512MB SLC NAND flash Display I/F – MIPI interface Connectivity – Gigabit Ethernet SDIO WiFi/BT (AP6356S) Audio SPDIF_IN/SPDIF_OUT LINE_IN/LINE_OUT 2x Audio headers (MIC_Connector & SPK_Connector) USB – 1x USB 2.0 OTG Expansion – 2x PCIe ports Misc – 6x ADC Keys, IR_IN/IR_OUT, UART Interface (RS232) The second S420 board is based on A113X SoC, and comes with less features (no display, no Ethernet, no PCIe…), less memory: SoC – Amlogic A113X […]
Huawei Introduces Kirin 970 Mobile SoC with Built-in Neural Processing Unit for Artificial Intelligence Applications
Huawei has unveiled their latest Kirin 970 SoC for premium smartphone at IFA 2017. The processor features an 8-core CPU, and a new 12-core GPU, but what makes this new processor stands apart it a dedicated Neural Processing Unit (NPU) to accelerate tasks used for artificial intelligence, with the company claiming the NPU delivers 25 times the performance with 50x greater efficiency compared to a quad core Cortex A73 processor for AI computing tasks. In practical terms, Kirin 970 could process 2,000 images per minute in an unnamed benchmark image recognition test. The press release also mentions the processor will pack 5.5 billion transistors packed into 1 cm² and be manufactured using a 10nm “advanced processor”. But they did not go into much further details about the specs, so instead, I used info from Anandtech and the slide above to derive Kirin 970 technical specifications: CPU – 4x ARM Cortex […]
Google Assistant News – AIY Voice Kit For Sale, Offline Support, 3rd Party Smart Speakers Announced
There’s been a lot of development related to Google Assistant in the last few days. First, Google provided an update for AIY Projects, with their AIY Projects Voice Kit now available for pre-order on Micro Center for $35 including a Raspberry Pi 3 board, making the kit virtually free, although you may also purchase it. Note that Micro Center blocks traffic originating from some countries, so I had to use Zend2 to access the site. [Update 10/09/2017: You can also get it from Seeed Studio for worldwide shipping] Google also announced the Speech Commands Dataset with 65,000 one-second long utterances of 30 short words, which they are in the process of integrating with the next release of the Voice Kit, and will allow the devices to respond to voice commands without the need for an Internet connection. So if you lose your Internet connection, or want to isolate your Voice […]
ReSpeaker 4-Mic Array is $25 Quad Microphone Add-on Board for Raspberry Pi
Last year, Seeed Studio launched ReSpeaker WiFi Audio / IoT board based on Mediatek MT7688, as well as an optional microphone array board with 7 microphones and 12 LEDs. Later on, they introduced a $10 2-mic array board for Raspberry Pi Zero (W), and today the company has started to take orders for ReSpeaker 4-Mic Array for Raspberry Pi board for $24.50 plus shipping. Respeaker 4-Mic Array board specifications: Audio X-Powers AC108 quad-channel ADC with I2S/TDM output transition 4 Microphones Expansion 2x Grove interfaces (1x I2C, 1x GPIO port using pins 12 & 13) 40-pin Raspberry Pi compatible header Misc – 12 LEDs (APA102) connected over SPI, GPIO5 enables power Dimensions – 65mm x 65mm x 9mm Weight – ~20 grams The board will give Raspberry Pi board the ability to do Voice Activity Detection (VAD) aka “hot word” detection, estimate Direction of Arrival (DoA) and show the direction via the LED ring, just like Amazon Echo or Google Home. I’m using an Orange Pi Zero board with a single microphone with Google Assistant and while it works fine most of the […]
