To use the translation function of the Timekettle M3, there are different modes that are suitable depending on the application scenario. Touch mode is recommended for one-to-one conversations and requires you to touch the earpiece to start translation. This mode allows you to speak without manual pauses, which makes communication easier. So you need to touch the earpiece to activate the translation, but there is no need to do this with every sentence as the function works continuously as long as the mode is active.
