Filetypes?
Whatever your system allows:
• .mov, .avi, .wmv, .mpg
• .wav, .vob, .mp3,
Annotation is stored in Elan Annotation Format (.eaf). Does not impact underlying files
– XML, schema-based format (= a good thing)

Today’s session
• Preparing and creating a new ELAN
project
• Segmenting Audio
• Transcribing Segments
• Analysing transcribed data
• Exporting transcriptions and creating
materials

Preparing media files
• Convert and concatenate video files
– Avidemux (PC)
– Format Factory (PC)
– Mpeg Stream Clip (Mac)
– Final Cut Pro (Mac)
• Extract audio from video if required (.wav)
• Name all media files consistently
• Store all media files consistently
• Test out your entire workflow before
beginning work!

Starting a new project
• New file
• Select media (up to 4 video files can be jointly
annotated)
• Pick audio (.wav) file first
• Choose a transcription ‘template’ to suit your
project; existing templates can be tailored
– http://tla.mpi.nl/tools/tla-tools/elan/thirdparty/
• Name annotation file the same as audio file
(e.g fileX.mpg, fileX.eaf)
• Set your Automatic backup to 5 minutes.
File>Automatic Backup>5 minutes.

Synchronizing Media
• Media-Synchronization mode
• Don’t forget to make a time mark at the
start of recording
![Page 16: 175-428 Seminars in Descriptive Linguistics – Topics in ...blogs.arts.unimelb.edu.au/.../uploads/2013/03/ElanPresentation2013.… · Elan • Complex annotations of video and audio](https://reader033.vdocuments.net/reader033/viewer/2022042419/5f353ad7a857e511bc6b6690/html5/thumbnails/16.jpg)
Linguistic Type • Stereotype
– None - means each tier of this type will be independent of other tiers. No overlapping annotations
– Time Subdivision - the parent tier can be sub-divided into smaller units, which, in turn, can be linked to time intervals (contained in the parent tier) (no gaps permitted). e.g., words in a sentence
– Symbolic Subdivision - smaller units cannot be linked to a time interval
– Included In - annotations fall within the borders of the parent tier (gaps permitted)
– Symbolic Association - 1 to 1 mapping of child and parent tier. e.g., one sentence on a parent tier has exactly one free translation. Or one word has exactly one gloss

None - means each tier of this type will be
independent of other tiers. No overlapping
annotations
This type divides the annotation into
time-aligned chunks (e.g. utterance
units or intonation units)

Time Subdivision - the parent tier can be sub-
divided into smaller units, which, in turn, can be
linked to time intervals (contained in the parent
tier) (no gaps permitted).
• e.g., words in a sentence
• Inherit the time characteristics of the parent
tier but each have their own time association
within the parent item

Symbolic Subdivision - smaller units
cannot be linked to a time interval
• Units that combine to make up larger
units, e.g., morphemes and words
that are part of higher order units but
have no direct time association

Segmenting Files
• Makes transcription more efficient
• Can be done in a number of ways
– Manually
– Quick Segmentation
– Audio Analyser
• Choose what best suits your project

Audio Recognizer -
• Chunks the media according to ‘silence’
• You can determine what silence is and
how long it should be
• There are also
– BAS – WebMAUS Basic
– AAM – LR Phone level audio segmentation
