It is an excel spreadsheet that contains all of the consonants and where they should be produced in the mouth. It also shows which consonants are voiced and describes the place and manner of production. I made it to keep all consonant information together and to get a better sense of where the consonants are produced in the mouth. I used this in my graduate phonetics course to help me study and group the consonants together. Hopefully, you find it as helpful as I did.
