COVID-19 has brought a variety of challenges for industries that traditionally congregate workers in
office environments. While what the future workplace will look like is still unclear, voice-controlled
devices and other methods may help us stay safe as alternatives to pressing communal buttons and
touching workplace electronics needed to be productive throughout the day.
As part of a new healthy workplace protocol when we return to offices and facilities, it may not be
surprising if you’re asking a voice-controlled elevator device to navigate to your office.
“Voice control technologies have been around for some time and are already present in intelligent
agents in our homes and in many systems as a way to improve interfaces between humans and
devices,” notes IEEE Life Senior Member Raul Colcher. “It is only natural that they are now used to
prevent physical contact and the spread of infections.”
Corporate offices have been slower to adopt these types of technologies for employees but IoT-
connected, voice-controlled and automated devices with Bluetooth and wireless local area network
connectivity could prevent employees from physically interacting with high-touch buttons,
appliances and hardware.
“A simple order – through the user’s voice or cell phone – will be translated into control signals and
sent over the network to the device, which in turn, will execute the command,” explains IEEE Senior
Member André Leon Gradvohl. “In the case of voice-controlled systems, programs that use artificial
intelligence decode the voice and understand the command vocalized by the user, translating it into
signals for the controlled device. Those artificial intelligence programs use machine learning
algorithms to learn to interpret the orders received in the form of sound, and to transcode them into
a command that the device answers.”
While IEEE Senior Member Kevin Curran agrees that voice control technology is a great next step to
limiting transmission, he warns that voice authentication must also be implemented to protect
employee and company privacy.
“The main barrier to any widespread adoption has been the problem of aural eavesdropping,” says
Curran. “Quite simply, casual or malicious bystanders may overhear private information spoken by
screen readers or users.”
Voice authentication is a biometric method that understands and recognizes the unique and
individual sound of a speaker’s voice. This is often used with voice-controlled passwords to ensure
privacy is aurally maintained — even if there is an eavesdropper around.
Innovative ways to utilize Voice Control and IoT device technologies in corporate environments may
provide us with valuable protection that we need when workforces come physically together again.
