# [amadaptadddata] Module Configuration

The `amadaptadddata` module accepts acoustic adaptation audio and transcript data, along with an existing acoustic model, and analyzes the data and how well the current model fits with the data. It creates an accumulator file that is subsequently used to update the acoustic model parameters.

Note: Currently you can adapt only GMM models, not the newer, better-performing DNN acoustic models. Generally, GMM model adaptation produces models that are still inferior to the out-of-the-box performance of DNN models.

## Input and Output

Mode | Input | Output | Description
--- | --- | --- | ---
|  |  | The `amadaptadddata` module does not accept input streams or write to an output stream. All inputs and outputs are file based.

Example:

    output <- amadaptadddata(–, input)
