Speech Recognition and Understanding on Hardware-Accelerated DSP

A smart home controller that responds to natural language input is demonstrated on an Intel® embedded processor. This device contains two DSP cores and a neural network co-processor which share 4MB SRAM. An embedded configuration of the Intel® RealSpeechTM speech recognizer and intent extraction engine runs on the DSP cores with neural network operations offloaded to the co-processor. The prototype demonstrates that continuous speech recognition and understanding is possible on hardware with very low power consumption. As an example application, control of lights in a home via natural language is shown. An Intel® development kit is demonstrated together with a set of tools. Conference attendees are encouraged to interact with the demo and development system.
