Hi Daniel. I’m trying to create the Italian track audio of Hal9000’s TROS: Ascendant Edit. I have to add some original lines that are not included in the original movie. Unfortunately I don’t have professional microphone to record that lines. I can use iPhone, iPhone earphones (cable and wireless) or mic from MacBook or Sony a6400. I have some questions:

is it possible reach a good quality with this instruments?
is it possible change the vocal timbre of a single voice to make two or more differents voices?
can you help me to create Kylo Ren’s mask voice effect?
I’m using Adobe Audition.
Sorry if some questions are not to your competence.
