When typing works
Text is useful on a train, in a shared room or when you want to get a name or detail exactly right. It also gives you a visible thread to look back through.
A longer message is optional. One clear question, observation or update is enough to start an exchange.
When voice works
A call can suit a conversation where speaking is easier than typing. Choose a place where you are comfortable using the microphone, and check the app’s call controls before starting.
Voice recognition can mishear a name or phrase. If a reply follows the wrong detail, correct it clearly; typing the word can help when pronunciation is ambiguous.
Switching modes
End the call when you want to return to text. If the topic needs clarification, add a short recap rather than assuming every detail of a spoken exchange has been retained exactly.
Starting a call requires microphone access. Listening to a spoken reply and transmitting your own speech are different actions; check the browser’s permission indicator if you are unsure whether the microphone is in use.
Try one small exchange
Start with a familiar topic, such as what you are watching or a game you have been playing. Ask a follow-up and try the same topic in text. Choose the format you find easier to use in that setting.
