# LangIdSegLif

The `LangIdSegLif` task reads in language identification features from file, processes the data in fixed-sized chunks, and returns the language identification results for each chunk.

## Parameters

Parameter | Description | Required
--- | --- | ---
Type | The task type. Set to `LangIDSegLif`. | Yes
File | The language identification feature (.lif) file to process. | Yes
ClassList | A list of language classifiers to use. |
ClassPath | The path to the directory containing the language classifiers. |
LangList | A subset of languages to use from the classifier list file. |
MinPhoneRate | The minimum phone rate (phones per second). |
NBest | The maximum number of language candidates to include in the output file. |
Out | The file to write language identification results to. | Yes
SegSize | The maximum results segment size. |

Note: The `ClassList` parameter is required only if you want to change the audio sample rate, or if you want to use your own custom classifiers. You might also need to specify the `ClassPath` parameter, depending on the location of the classifier files.

## Example

    http://localhost:13000/action=AddTask&Type=LangIdSegLif&File=C:\Data\Speech.lif&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang5.ctm

This action uses port `13000` to instruct IDOL Speech Server, which is located on the local machine, to identify languages in the `Speech.lif` file using the language classifiers specified in the `OptClassSet` list, and to write the identification results to the `SpeechLang5.ctm` file.
