The ESP Private Agents platform aims to ease the development of ESP32-based AI voice assistants with on-device processing

Espressif has just introduced the ESP Private Agents platform to help developers build local, private, and customizable AI assistants for ESP32 devices running on-device, although they can also support hybrid AI workloads with a mix of on-device and cloud processing. The ESP Private Agents platform offers a unified framework that allows developers to build applications combining speed, vision, automation, and agent-based interactions, for example, a multi-lingual, on-device voice agent (aka smart speaker) or task-oriented agents that automate workflows. The solution is built on AWS cloud services using AWS Fargate as a primary application platform and Amazon Bedrock Foundation Models as backend LLM systems. It not only works with ESP32-power devices with speaker and microphone, but also with mobile apps and web clients. Espressif released a Web-based demo, which you can use as a text-based chatbot or as a voice assistant leveraging the speaker and microphone on your computer. The company […]

MIPI SoundWire I3S (SWI3S) targets high-bandwidth, low-latency audio applications

The MIPI Alliance has recently released the SoundWire I3S (MIPI SWI3S v1.0) specification for high-bandwidth, low-latency audio applications which unify control and data over a single, power-efficient interface. SWI3S builds upon the two-pin, multi-drop architecture of MIPI SoundWire released in 2014, and offers higher bandwidth, low power consumption, much better noise immunity, and support for scalable multi-device topologies to meet the increasing requirements of embedded audio systems. MIPI SWI3S v1.0 supports data rates up to 76 Mbps against 24 Mbps for the earlier SLIMbus and SoundWire audio interfaces, and improves noise immunity by operating in “forwarded clock” or “differential low voltage signaling”. It also implements a range of new features such as Hubs, multiple PHY support, control CRC, power-saving techniques, and more. MIPI SoundWire I3S key features: Transports audio data, control commands, interrupt signals, and synchronization information over a unified two-pin link Forwarded bit clock single-ended (FBCSE) and differential low-voltage […]
