# Document Fields for Import Tasks

You can customize how documents are processed by import tasks, by adding the following fields to your documents.

Note: The Lua script that adds the document fields must run before the import tasks.

## AUTN_NEEDS_TRANSCRIPTION

To use an IDOL Speech Server to extract the speech from a document that represents an audio or video file, you must add the field `AUTN_NEEDS_TRANSCRIPTION` to the document. The `IdolSpeech` task only runs on documents that have this field. The field can have any value. For more information about the `IdolSpeech` task, see Analyze Speech.

## AUTN_FORMAT_CORRECT_FOR_TRANSCRIPTION

To bypass the transcoding step of an `IdolSpeech` task, add the field `AUTN_FORMAT_CORRECT_FOR_TRANSCRIPTION`. The field can have any value. Documents that have this field are not sent to a Transcode Server. For more information about the `IdolSpeech` task, see Analyze Speech.

## AUTN_AUDIO_LANGUAGE

To bypass the language identification step of an `IdolSpeech` task add the field `AUTN_AUDIO_LANGUAGE`. The value of the field must be the name of the IDOL Speech Server language pack to use for extracting speech. Documents that have this field are not sent to the IDOL Speech Server for language identification. For more information about the `IdolSpeech` task, see Analyze Speech.

## AUTN_NEEDS_MEDIA_SERVER_ANALYSIS

To perform analysis on media files using the `MediaServerAnalysis` task, you must add this field to every document that you want to analyze. The field can have any value.

## AUTN_NEEDS_IMAGE_SERVER_ANALYSIS

To perform analysis on image files using the `ImageServerAnalysis` task, you must add this field to every document that you want to analyze. The field can have any value.

## AUTN_NEEDS_VIDEO_SERVER_ANALYSIS
