# Run Analysis on Specific Documents

To run speech-to-text on specific documents, you can modify the criteria in `scripts/IdolSpeech.lua`, or you can use the `IdolSpeech` import task and write your own Lua script to identify the documents to process. The `IdolSpeech` task only processes documents that have the field `AUTN_NEEDS_TRANSCRIPTION`, so your script must add this field to any document that you want to process.

The following example shows how to configure the `IdolSpeech` task in the CFS configuration file:

    [ImportTasks]
    Pre0=Lua:Identify_Audio_Files.lua
    Pre1=IdolSpeech:IdolSpeechSettings

    [IdolSpeechSettings]
    IdolSpeechServers=server:15000
    IdolSpeechLanguage=ENUK

The `Pre0` import task runs a Lua script that determines whether a file is suitable for transcription. You must write this script. The script must add the field `AUTN_NEEDS_TRANSCRIPTION` to any documents that you want to process. You can include conditions in the script to filter documents based on the document source, file type, or metadata extracted by KeyView.

The `Pre1` import task is the `IdolSpeech` task. It specifies the name of a section in the configuration file that contains the settings for the task. In this example the section is named `IdolSpeechSettings`.

The `IdolSpeechServers` parameter specifies the host name or IP address, and ACI port, of your IDOL Speech Server. To use multiple Speech Servers, see Use Multiple Speech Servers.

The `IdolSpeechLanguage` parameter is optional and specifies the language pack to use for transcription. You can set this parameter when all of your audio files are in the same language. If your audio files are in different languages, remove `IdolSpeechLanguage` so that Speech Server uses language detection to detect the language for each document. For more information about language identification, see Language Identification.

If you prefer to send files to your IDOL Speech Server by writing them to a shared folder, add the `IdolSpeechUseSharedPath` and `SharedPath` parameters to the configuration:

    [ImportTasks]
    Pre0=Lua:Identify_Audio_Files.lua
    Pre1=IdolSpeech:IdolSpeechSettings

    [IdolSpeechSettings]
    IdolSpeechServers=server:15000
    IdolSpeechLanguage=ENUK
    IdolSpeechUseSharedPath=true
    SharedPath=\\server\SharedPath

Setting `IdolSpeechUseSharedPath=TRUE` instructs CFS to send files to Speech Server by writing them to the shared folder. specified by the `SharedPath` parameter.

For more information about the parameters that you can use to configure this task, refer to the Connector Framework Server Reference.
