Overview

WhisperExtractor is a disruptive technology that addresses a major challenge in the voice user interaction space - low power consumption.
With the increasing adoption of voice user interfaces in everyday objects, it has become critical to have efficient and low-power solutions for voice processing.

Our product uses a mixed-signal architecture to efficiently extract the Mel Frequency Cepstrum Coefficients (MFCC) needed for keyword spotting, speaker recognition, and natural language understanding applications. By doing so, it reduces power consumption by up to 99%, enabling always-on listening at a power budget of just µW, on a 32kHz crystal. This disruptive technology allows for constant monitoring of the voice without the need for frequent charging or compromising battery life.

Key features

  • µW power consumption
  • Integted Voice Activity Detection
  • Running on a 32kHz clock in the always on domain
  • Quick integration, no software required
  • No ADC required, from analog to feature extraction
  • Evaluation kit available

Audio Validation in Multimedia Systems and its Parameters

In the massive world of multimedia, sound stands as a vital component that adds depth to the overall encounter. Whether it's streaming services, video games, or virtual reality, sound holds a crucial role in crafting immersive and captivating content.

Using audio codecs IP as the digital audio hub in mobile multimedia systems

By integrating an audio analog codec that implements the 'audio hub' functionality and is able to process and mix audio signals from asynchronous sources, system designers can free the scarce main processor resources for more relevant tasks and simplify the system design, thus achieving a more effective solution.

Application Hardware Modeling: Selective modeling for early prediction of subsystem performances through simulation

The virtual validation of subsystem performances (Pop-up Noise, Signal-to-Noise Ratio, Power supply Noise, Power consumption...) requires the modeling and simulation of complete subsystems. Application Hardware Modeling (AHM) consists in addressing the risks of performance degradation while integrating a Silicon IP in its Integrated Circuit (IC) and this IC on its Printed Circuit Board (PCB). The selection of relevant models for a subsystem performance, along with the creation and validation of models through equivalence checking, are the basics of Application Hardware Modeling for right-on-first-pass subsystems!
