# LangIdTrain

The `LangIdTrain` task reads in a set of language identification feature (.lif) files created from audio representing a single language (using the LangIdFeature task), and uses this data to train a new language classifier.

## Parameters

Parameter | Description | Required
--- | --- | ---
Type | The task name. Set to `LangIdTrain`. | Yes
Context | The group size to use when combining features during training. |
DataList | A list of language identification feature files. | Yes
DataPath | The path to the directory containing the feature files specified in the DataList. | Yes

## Example

    http://localhost:13000/action=AddTask&Type=LangIdTrain&DataList=ListManager/FrenchList&DataPath=C:\LangID\Data&Out=FRFR.lcf

This action uses port `13000` to instruct HPE IDOL Speech Server, which is located on the local machine, to use the feature files specified in the `FrenchList` list and saved in `C:\LangID\Data` to create the `FRFR.lcf` language classifier file.
