Mote is a Chrome extension that became popular this year because it made it easy for teachers and students to add voice recordings to Google Slides, Google Classroom, and Google Forms. The latest update to Mote, released today, lets you add voice recordings not only to the questions in your Google Forms but also to the answer choices and feedback section in Google Forms.
The previous version of Mote let you add voice recordings into the question line. The updated version lets you also add voice recordings into the answer choices (for multiple choice questions) and into the feedback section of the answer key that you create for quizzes in Google Forms. All of those things are demonstrated in this short video.
