The home device and automation opportunity is growing at an impressive rate, with some analysts suggesting it might be worth over $81 billion by 2023. along side the evolution of home automation, there has been a burgeoning demand for brand spanking new methods of human-machine interaction (HMI) that substitute or supplement traditional touch-based user interfaces.

One of the foremost popular methods that has emerged is voice control, thanks partially to Amazon’s Alexa voice controlled, personal assistant technology, that was first utilized in their Amazon Echo smart speakers. The underlying technology behind this is often Alexa Voice Service (AVS) which Amazon has made available to third-party developers. Through AVS, developers can allow end users to perform a spread of tasks starting from fixing to-do lists to playing audiobooks. However, for us within the IoT industry, the foremost exciting aspect of AVS is that the ability to regulate other smart devices through voice commands.

Introducing the Qualcomm Home Hub 100

The Qualcomm Home Hub 100 is driven by a tri-mode (dual band Wi-Fi, BLE and 802.15.4) SoC (QCA4020) that permits developers to package AVS control directly into their devices. this is often a possible game changer because developers can integrate AVS without having to believe the presence, correct setup, and connectivity to an existing external Alexa home hub. The platform currently provides tri-mode connectivity (Wi-Fi, Bluetooth 5.0 and 802.15.4 (Thread and Zigbee 3.0)) on one contribute conjunction with AVS, which may leave interconnectivity with a good range of devices. additionally , developers even have the choice to regulate other Alexa-supported devices using their Qualcomm Home Hub 100-based implementations.

While smart home automation probably conjures up images of digital thermostats and intelligent light bulbs–cool use cases indeed–we think developers will start to use the house Hub 100 into even more devices. This technology is particularly useful to exchange and/or complement touch-based user interfaces in devices. As well, there’s no got to make accommodations (like yelling) for a hub which can be located in another room faraway from the device to be controlled; or a tool that’s not fully reachable. Use cases could range from smart kitchen appliances like telling a hot stove with an overflowing pot to show its temperature down, or commanding devices like smoke detectors in hard-to-reach places to show off. the utilization of voice commands also can be particularly beneficial to users with accessibility challenges. Despite the platform’s name suggesting use cases round the home, the platform also can be used in other areas where voice control could be needed, like in health-care systems, industrial settings, or situations where the spread of an illness might be reduced by eliminating touch-based interfaces shared by multiple users.

Platform Specifics at a look

The Home Hub 100 platform builds off of the Qualcomm® QCA4020 with integration to those two additional processors from Synaptics:

CX20921: provides far-field voice processing and embedded smart voice-triggering, along side voice control, voice search, and VoIP/speakerphone capabilities, also as access to the speech input processor, wake-on-voice, noise suppression, and full-duplex acoustic echo cancellation capabilities.
CX22721: provides amplified audio playback.


HMI through voice control is proving to be hugely popular because of devices just like the Amazon Echo, and more generally, AVS. Now developers can use  AVS capabilities directly into their devices using Qualcomm Home Hub 100, which shows that voice controls capabilities are not limited it is vast. Such capabilities are bound to make devices even more beneficial and accessible to all or any users.

Developers can start by using the Ehong EH-MEVK-AVS hardware development kit that features the Qualcomm Home Hub Platform 100.
