Collecting Food and Drink Intake Data With Voice Input: Development, Usability, and Acceptability Study

Collecting Food and Drink Intake Data With Voice Input: Development, Usability, and Acceptability Study

These systems, such as Amazon Alexa, Google Assistant, and Samsung’s Bixby, allow users to talk to a device rather than typing or pressing a button.
