# SpkIdEvalStream

DEPRECATED:

The `SpkIdEvalStream` task is deprecated in HPE IDOL Speech Server version 11.4 and later. Use the IvSpkIdEvalStream task instead.

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

After you have trained a set of speaker templates, use the `SpkIdEvalStream` task to identify any sections of an audio stream where the trained speakers are present.

NOTE:

To process an audio file, use the SpkIdEvalWav task.

## Parameters

Parameter | Description | Required
--- | --- | ---
Type | The task name. Set to `SpkIdEvalStream`. | Yes
AllowEmpty | Whether to produce gender labels as output if no speakers are specified. |
ClosedSet | Whether the task that you are running is a closed-set test. |
DiagFile | The name of the file to write diagnostic information to. |
DiagLevel | The level of detail to include in the diagnostic information. |
DiscardShort | Exclude segments shorter than a specific duration from further analysis. |
MinNonSpeech | The minimum length of non-speech segments. |
MinSpeech | The minimum length of speech segments. |
Out | The file to write the results to. |
Sfreq | The sample frequency of the audio stream to process. |
TemplateExt | The file extension to use for template files. |
TemplateList | A list file that lists multiple speaker template files to use. | Yes, if `TemplateSet` is not specified
TemplatePath | The path to the directory containing the speaker templates. |
TemplateSet | An audio template set file. | Yes, if `TemplateList` is not specified
ThreshScale | The rate at which to scale the thresholds. |

## Example

    http://localhost:15000/action=AddTask&Type=SpkIdEvalStream&File=C:\Data\Speech.wav&TemplateSet=speakers.ats&ClosedSet=False&Out=results.ctm

This action uses port `15000` to instruct HPE IDOL Speech Server, which is located on the local machine, to search the audio stream for speakers based on the template set file `speakers.ats`, and to write the identification results to the `results.ctm` file. Because the test is set to be open-set, HPE IDOL Speech Server marks sections where no speaker scores above their respective thresholds as `Unknown_`.
