Overview

The Age of the Voice UI

Blending a neural network (NN) with digital signal processing, the Cadence® Tensilica® HiFi 5 DSP easily executes the two complementary aspects of speech recognition: audio pre-processing and speech recognition/keyword detection. Voice-controlled appliances, whether in the home or in automobiles, can achieve rich voice interactions with the HiFi 5 DSP's leading-edge performance.
