Intel Quark S1000 “Sue Creek” Processor to Support On-Chip Speech Recognition

Intel may have announced plans to discontinue several of their IoT boards, but based on some documents I received, the company has not given up on the Quark family, although they may have given up on the Intel architecture for low power microprocessor, as Intel Quark S1000 – codenamed “Sue Creek” – will feature two Tensilica LX6 cores (yes, just like ESP32), and is designed to handle speech recognition at the edge (e.g. locally), so some of your voice commands should still work when Internet is down. Intel Quark S1000 key features and specifications: Digital Signal Processors Dual Tensilica LX6 cores @ 400 MHz with HiFi3 DSP Single precision scalar floating-point instructions 16KB 4-way I$; 48KB 4-way D$ Up to 2400 DMIPS, 3.2 GMACS (16×16), 800 MFLOPS of Compute Speech Accelerators A GMM (Gaussian Mixture Model) and neural network accelerator Low power keyboard and limited vocabulary recognition Up to 9.6 […]

Qualcomm Announces Audio Platforms for Smart Speakers, Headphones, and Hearables

Smart speakers are getting a lot of buzz recently with products like Amazon Echo or Google Home, and many home automation products are advertised with Amazon’s Alexa support, so that they can be controlled by voice commands. Qualcomm is now going after this market, and others audio markets via 5 new platforms for streaming audio, high resolution audio, wireless audio, USB -C audio devices – due to the “death” of the 3.5mm headphone jack -, and hearables. The five platforms include: Bluetooth and BLE Audio SoCs such as Qualcomm CSRA68100 for premium wireless speakers and headphones. The SoC comes with flash, DSP, a 2-ch audio CODEC, USB & I/Os interfaces. Qualcomm QCC3xxx entry-level Bluetooth audio SoC for mid to low-cost Bluetooth headsets and speakers. Qualcomm WHS9420 (192kHz/24-bit audio) and WHS9410 (entry-level) USB-C audio SoC for USB-C headphones Qualcomm DDFA Digital Amplifier Technology with CSRA6xxx amplifier Smart Speaker Platform shown above […]

Google Assistant SDK Turns Your Raspberry Pi 3 into Google Home

Google Home allows you to select music, control your home automation system and more with voice commands, but now you can do the same with a Raspberry Pi 3 as Google released a developer preview (alpha v1) of the Google Assistant API that works on Raspberry Pi 3, and other development boards running Debian or Ubuntu. Functionalities are limited right now, with RPC API and Python sample code, but it only works with English language, and features such as timers & alarm, playing music, news, or podcasts, and precise location are not supported. Location is determined using your IP address only, and if you’re using some third party services / products such as Uber or Hue, you’ll need an actual Google Home device for initial setup. Google has provided instructions to use Google Assistant SDK with Raspberry Pi 3 board. First you’ll need a USB microphone ($5.99 on Amazon), and […]
