# CustomLanguageModel

NOTE: Custom language models are supported only with the legacy speech-to-text models (see the ModelVersion parameter).

A comma-separated list of custom language models to use. For each custom language model, specify the identifier and interpolation weight separated by a colon.

TIP: To obtain a suggested interpolation weight for a custom language model, see the action ListCustomSpeechLanguageModels.

Any custom language model that you specify must have been trained with the same language pack you specify with the parameter LanguagePack.

You might want to use custom language models when you are processing speech that includes specialized words that are not present in the standard vocabulary, for example specialized medical terms. For more information about custom language models, refer to the Media Server Administration Guide.
