ClosedSet

Set ClosedSet to False to use open set language identification.

By default, HPE IDOL Speech Server Reference uses closed set language identification. In this case, it identifies any speech in the audio as one of the configured language classifiers, even if the confidence that the speech matches the language is very low. This option is most useful when you know that the speech must belong to a particular set of languages, or when you want to maximize the amount of speech that you classify. For poor quality audio, or when the speech is not well defined, this option might result in false positives.

In open set language identification, HPE IDOL Speech Server Reference identifies the best match from the configured language classifiers, and then calculates a confidence value. If the confidence is below a configured threshold, HPE IDOL Speech Server Reference labels the language as unknown. This option might be useful if you are not sure what languages to expect in your data. You might also want to use this method if you want to identify whether the speech belongs to a particular language, and do not need to identify the other possible languages.
