     # @param model [String] The identifier of the model to be used for the recognition request.
     # @param customization_id [String] The GUID of a custom language model that is to be used with the request. The base model of the specified custom language model must match the model specified with the `model` parameter. You must make the request with service credentials created for the instance of the service that owns the custom model. By default, no custom language model is used.
     # @param acoustic_customization_id [String] The GUID of a custom acoustic model that is to be used with the request. The base model of the specified custom acoustic model must match the model specified with the `model` parameter. You must make the request with service credentials created for the instance of the service that owns the custom model. By default, no custom acoustic model is used.
-    # @param customization_weight [Float] If you specify a `customization_id` with the request, you can use the `customization_weight` parameter to tell the service how much weight to give to words from the custom language model compared to those from the base model for speech recognition.   Specify a value between 0.0 and 1.0. Unless a different customization weight was specified for the custom model when it was trained, the default value is 0.3. A customization weight that you specify overrides a weight that was specified when the custom model was trained.   The default value yields the best performance in general. Assign a higher value if your audio makes frequent use of OOV words from the custom model. Use caution when setting the weight: a higher value can improve the accuracy of phrases from the custom model's domain, but it can negatively affect performance on non-domain phrases.
+    # @param language_customization_id [String] The GUID of a custom language model that is to be used with the request. The base model of the specified custom language model must match the model specified with the `model` parameter. You must make the request with service credentials created for the instance of the service that owns the custom model. By default, no custom language model is used.
     # @param base_model_version [String] The version of the specified base `model` that is to be used for speech recognition. Multiple versions of a base model can exist when a model is updated for internal improvements. The parameter is intended primarily for use with custom models that have been upgraded for a new base model. The default value depends on whether the parameter is used with or without a custom model. For more information, see [Base model version](https://console.bluemix.net/docs/services/speech-to-text/input.html#version).
     # @param inactivity_timeout [Integer] The time in seconds after which, if only silence (no speech) is detected in submitted audio, the connection is closed with a 400 error. Useful for stopping audio submission from a live microphone when a user simply walks away. Use `-1` for infinity.
     # @param interim_results [Boolean] Send back non-final previews of each "sentence" as it is being processed. These results are ignored in text mode.
