Communication, sure. Recording? Nope. Phones can determine your password by the different sounds keyboard keys make. The microphones are very sensitive and audio compresses well for storage until a transmit opportunity arrives.
You must change your operation security to adapt to your new normal. It may not only be your phone listening. You can hot air the mics off the phone's board, and use a pair of headphones for all your communication needs, with a physical mute button.

Ikr... Surely building a Faraday cage and depositing your mobile phone into it will prevent any communication. At least during that time.
