Transcription conventions

Transcription of the spoken data

The transcripts are orthographic transcriptions and include only basic details of spoken language properties. For example, pauses are marked but their length is not marked. Spoken language features marked in the transcripts include pauses, false starts, incomprehensible words, etc. The idea is that the transcription should be as legible as possible by a wide range of users.

In this version of COREFL (version 1), transcriptions are provided only when the spoken texts are in English (i.e., English native subcorpus, L2 English learner corpora) or in Spanish (i.e., Spanish native subcorpus).
