# Lang

The `Lang` parameter sets either the name of the language pack used for operations in the module (speech-to-text, transcript alignment, and so on), or the name of the base language identification feature extraction pack (for language identification tasks). Specify the name of the configuration section in the IDOL Speech Server configuration file where the settings for the language pack or feature extraction model are configured.

- For speech-to-text processing (using the `stt` module), set the parameter to the name of the language pack, for example `ENUK`. For the `stt` module, you must set the `Lang` configuration parameter using the corresponding action parameter.

- For transcript alignment (using the `align` module), set this name to the language pack to use for alignment.

- For text normalization (using the `textnorm` module), set this name to the language pack to use for normalization. For the `textnorm` module, you must set the `Lang` configuration parameter using the corresponding action parameter.

- For language model building (using the `lmbuild` module), set this name to the base language pack to use to create the custom language model. For the `lmbuild` module, you must set the `Lang` configuration parameter using the corresponding action parameter.

- For language identification (using the `lidfeature` module), set this name to the feature extraction models used for language identification.

  NOTE:

  A base language identification feature extraction pack, `Syls`, is provided with IDOL Speech Server and is configured for use with 16k broadband data. You should not need to change this setting unless you need to use IDOL Speech Server with 8k telephony data, in which case you must set `Lang` `Syls-tel`.
