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.
Applications for Education
Adding voice recordings to Google Forms has a lot of potential classroom uses. Just having the option to listen to the question and answer choices improves the accessibility of your forms. You could also use the voice recording option to have students listen to question prompts in one language then identify the answer in another language. For example, you could record a prompt in Spanish then ask students to identify what you said by choosing an answer written or recorded in English.
