Click on the audio area at the beginning of a segment. Click on the small circle on the

vertical line in the desired tier in order to create a boundary.

Click on the audio area at the end of the selected segment, Click on the small circle on the

vertical line in the desired tier in order to create a boundary.

Boundaries are created also for pauses that last more than 200 ms.

Note that in Praat there is automatically a left and a right boundary in the sound file

(beginning and end) you are working on: DON'T ADD THEM.

3.2.8. Transcription strategy

Praat may contain various transcription tiers for one sound file (phonetic transcription

tier, orthographical tier, words tier, phonemes tier…), but those multiple tiers are not

hierarchically dependent. In the CorpAfroAs ELAN annotation model,

the annotation tiers are hierarchically dependent: ref is the main tier

directly related to time. It has two time associated tiers: tx and ft.

Then the mot tier is a child of tx tier, mb tier a child of mot tier, finally

ge and rx are associated to mb.

For this reason we recommend two or three ways of entering the transcription for

importation into ELAN.

As the mot tier can be generated in ELAN by tokenizing a text tier, the simplest procedure

is to prepare a transcription line in Praat containing as many (grammatical) words as

necessary for the mot tier. This line should be named ref@SP. When imported into ELAN,

that ref tier will be duplicated into a tx tier, which will be used to generate the mot line.

The initial (morphophonological) transcription of this tx tier will then be modified by hand

so that it becomes a broad phonetic line, with phonological words instead of grammatical

ones.

On the other hand, you may prefer to enter the broad phonetic transcription from the

start in the ref@SP tier of Praat, because you are planning to use Praat for some prosodic

or phonetic investigation for example. Then after importation into ELAN, you will have to

duplicate that ref tier as an intermediary tier whose annotations will be modified by hand

to reflect the grammatical words transcription. That intermediary tier will be tokenized

into a mot tier, then the mot tier will be made dependent on a tx line (created from

another copy of the ref), and the intermediary tier will be deleted. That process is more

complex than the previous one. See 4.3 for an alternative.
