Speaker Codes

Notes

  • Each speaker in our recordings is coded with a 3-letter code (ex: MOT). All speakers heard by a given participant have been assigned a unique code following the guidelines described below. Within each participant's folder is a list of all the speakers in all of their files and brief descriptions of each.

  • Speaker codes should all include information about the speaker's age (adult or child) and their gender.

  • For subject-specific codes, see the document Speaker Codes in the subject's file (if one doesn't exist, see Cast of Characters) within each subject's folder.

For every speaker in the file, there should be a note in Audio or Video coding issues defining who the speaker is. If these notes are not already there when you go to check the file, you are responsible for adding them.

Any code used should be listed on this page.

Single Speakers

Family members

  • MOT: mother

  • FAT: father

  • CHI: baby in our study (target child)

Non-family members

  • TOY: Toy that speaks or sings

  • TVS: Any sort of electronic noise: TV, radio, CD, iPad, etc.

  • EF_: female experimenter, with inital (e.g. EFS)

  • EM_: male experimenter, with initial (e.g. EMM)

  • BS_: babysitter, first letter of first name; specific names will be listed in the final speaker code document for each subject.

Other speakers that are close to the family (e.g. neighbors or family friends) are coded with the following formula:

  • A or C (adult or child)

  • F or M (female or male)

  • First initial

For example, a woman named Susan would be AFS (Adult Female Susan).

Speakers who are random people (e.g. waitresses, cashiers, passersby) are coded with the following formula:

  • A or C (adult or child)

  • F or M (female or male)

  • Number of appearance

For example, the first unknown adult female for a participant would be AF1. The second unknown male child would be CM2.

If a child's gender can't be determined, use "CH". For example, the first random child whose gender is unknown would be CH1.

If these unknown codes go above 9 for a given family (i.e. we've used AF1-AF9 and have more unknown adult females), use these codes, starting with the 10th:

- Adult females = X__

- Adults males = Y__
