Transcribing conversation

Spoken conversation is not written text. To study how people take turns, interrupt, hesitate and repair misunderstandings, you need a transcript that records how things were said as well as what was said.

Why ordinary spelling is not enough

A tidy written version of speech removes exactly the details that matter for interaction: pauses, overlaps, stretches, changes in pitch and loudness. The standard system used in conversation analysis was developed by Gail Jefferson (see Jefferson, 2004).

Basic principles

Common symbols

SymbolMeaning
[ ]Start and end of overlapping talk
=No gap between turns (“latching”)
(0.5)Timed pause, here half a second
(.)Micropause, shorter than about 0.2 seconds
:Stretched sound, e.g. so:
-Word cut off, e.g. I wa-
. ? ,Falling, rising and “continuing” intonation
underlineEmphasis
CAPITALSLouder than the surrounding talk
°quiet°Quieter than the surrounding talk
>faster< <slower>Speeded-up and slowed-down talk
↑ ↓Marked rise or fall in pitch
.hh hhIn-breath and out-breath
( ) (word)Unclear talk; a best guess

A worked example

01  Mia:   so did you (.) manage to get the tick[ets?
02  Ben:                                        [yeah I=
03  Mia:   =oh good
04         (0.8)
05  Ben:   they're for the (.) twe:lfth?

Other systems

For child language sampling, many clinicians and researchers use the CHAT format with CLAN software from the CHILDES project (MacWhinney, 2000). It records utterances, errors and morphology in a way that supports counting and analysis. Jefferson notation is designed for interactional detail rather than for automatic counting.

Practical tips

Rule of thumb. Include only the detail you can justify from the recording, and be consistent so the transcript can be checked.
