Jeff Zurita – Senior Applications Engineer
Deepwave Digital was founded with the mission to bring artificial intelligence (AI) capabilities to the radio frequency (RF) domain. Deepwave’s latest contribution to AI applications in RF communications is to integrate a fully functional FM radio that can intercept voice communications and transform received voice signals into text. This capability runs natively in its entirety on Deepwave’s premiere product, the Artificial Intelligence Radio Transceiver (AIR-T) without the need for a connection to a remote inference server.
The AIR-T is a small form factor, single board radio made for deployment on fixed, outdoor towers or mobile, portable applications. The AIR-T brings together a software defined radio (SDR) and a graphics processing unit (GPU) along with software support for deep learning operations.
A diagram showing the major components of the Deepwave Radio Automatic Speech Recognition (Radio-ASR) system is shown below.
In the Deepwave Radio-ASR system, a software implementation of a narrowband FM demodulator is integrated with pre-trained speech-to-text neural network software to convert speech received over the radio into a text output. This text output can be stored locally or delivered across a minimal capacity network for further processing or analysis.
The FM demodulator works with the General Mobile Radio Service signal standard to obtain the voice signal. Demodulated voice is fed to a speech-to-text application based on the NVIDIA NeMo™ framework. NeMo™ is a toolkit for building and training natural language processing applications that uses a modular approach to speech processing. This allows users to integrate separate functions as needed for their application.
The Deepwave Radio-ASR system is completely modular. Individual components can be exchanged or customized, for example, by incorporating other demodulation schemes, or language models for languages other than English. This application highlights the key benefits of GPU integration into SDR: the ability to easily leverage pre-trained AI models for a multitude of applications.
