# LangIdCumLif

DEPRECATED:

The `LangIdCumLif` task is deprecated in IDOL Speech Server version 11.5 and later. Identifying language on feature files is no longer supported. Use the LangId task to identify languages in a file or stream instead.

This task is still available for existing implementations, but it might be incompatible with new functionality. The task might be deleted in future.

The `LangIdCumLif` task reads in language identification features from file and returns the running language identification score at periodic intervals. This is the score for all the data from the start to the current point.

## Parameters

Parameter | Description | Required
--- | --- | ---
Type | The task name. Set to `LangIDCumLif`. | Yes
Beam | The beam width of the search process. |
ClassList | A list of language classifiers to use. |
ClassPath | The path to the directory containing the language classifiers. |
ClosedSet | Whether to use closed set or open set language identification. |
DiagFile | The file to write the diagnostic information to. |
DiagLevel | The level of detail to include in the diagnostic information. |
File | The language identification feature (.lif) file to process. | Yes
LangList | A subset of languages to use from the classifier list file. |
MinRate | 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:15000/action=AddTask&Type=LangIdCumLif&File=C:\Data\Speech.lif&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang2.ctm

This action identifies the language in the `Speech.lif` file using the language classifiers specified in the `OptClassSet` list. IDOL Speech Server writes the identification results to the `SpeechLang2.ctm` file.
