# LangIdCumStream

The `LangIdCumStream` task receives audio data as a binary stream and converts it into language identification features. It 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 `LangIdCumStream`. | Yes
Beam | The beam width of the search process. |
ClassList | A list of language classifiers to use. | Yes
ClassPath | The path to the directory containing the language classifiers. | Yes
DnnFile | The Deep Neural Network acoustic modeling file to use. |
Lang | The name of the language pack to use. | Yes
LangList | A subset of languages to use from the classifier list file. |
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. |

## Example

    http://localhost:13000/action=AddTask&Type=LangIdCumStream&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang3.ctm

This action uses port `13000` to instruct Speech Server, which is located on the local machine, to identify the language in the audio stream using the language classifiers specified in the `OptClassSet` list. The action instructs IDOL Speech Server to write the identification results to the `SpeechLang3.ctm` file.
