Accents and low-pass filtering

[Aniruddh Patel <apatel@xxxxxxx>]

Dear Colleagues,

I would like to create a version of this short YouTube video (of an
actress doing 21 different accents) in which the audio is low-passed
filtered, so that students can focus on the prosody of the different
accents:

I would also like to create another version in which both the audio and
the video are low pass filtered, so that one sees the slower time-scale
movements of the face while hearing the low-pass filtered voice.

Can anyone suggest how I might do this?

Regards,

Ani Patel
