For our friends who would rather not speak on the phone, we developed a Text-to-Speech (TTS) feature. TTS enables you to write your answers thanks to an integrated keypad. Your correspondent will receive your written answer as a voice message.
To activate TTS during a phone call: press to enable a keypad.
Type your answer and hit send , just as you would to send a SMS. Your correspondent will receive your answer as a voice message.
Note: Before you can use the TTS feature, you need to configure it. Setting up TTS explains how to proceed.
