ESP32 Tools Marry Alexa Service and AWS IoT


Espressif Systems has announced the availability of its Alexa Voice Service (AVS) Integration with the AWS IoT Core for ESP32-based connected devices. This solution relies on Espressif’s ESP32 wireless system-on-chip (SoC) and DSP Group’s DBMD5P audio SoC. The resulting ESP32-Vaquita-DSPG (shown), Espressif’s new development kit, provides seamless voice integration and cloud connectivity when creating IoT devices with a built-in Alexa Voice Service. As such, Espressif’s new solution will provide an easy, secure and cost-effective way for engineers to develop voice-controlled IoT devices.

Voice is becoming a standard way to interact with smart-home devices. There is an emerging trend to build a voice user interface (VUI) directly into smart devices, such as light switches, lamps, kitchen appliances and thermostats. Espressif’s ESP32 SoC already has a strong foothold in connected devices and is, therefore, the natural building environment for a VUI extension.

Espressif’s new Alexa built-in solution is powered by ESP32, Espressif’s Wi-Fi+BT/BLE combo system-on-chip, which provides unparalleled IoT performance, along with robust, power-efficient and secure connectivity. ESP32 has been paired with DSP Group’s DBMD5P audio system-on-chip, which enables clearer human-machine voice interactions in microphone-equipped devices. With a 2-mic array that allows for a 360-degree pick-up, the DBMD5P audio SoC provides high far-field voice recognition performance with its HDClear technology.
