Please read the instructions carefully. This study consists of two parts:
Part 1: You will be shown 15 sentences one after another. For each sentence, you will either type it on your phone or record it as a voice message as fast and as accurately as possible. The interface will indicate whether to type or speak.
Part 2: We will ask you to answer 12 simple questions. For each question you should imagine that you are in a chat conversation. We will first describe the context of the chat (who is the person, what is your relation to them) and then show you the chat window with the question. To submit an answer, you can decide whether you want to type or record a voice message and are free to compose multiple messages, just as you would in everyday chat conversations.
Note:
* This study is designed for mobile devices (Android or ios).
