# Automatic Speech Recognition with NVIDIA NeMo

***

## Overview

This example demonstrates:

* Preparing and preprocessing LibriSpeech data
* Fine-tuning QuartzNet ASR models
* Evaluating Word Error Rate (WER)

***

### Steps

{% stepper %}
{% step %}
**Data Preparation**

Prepare and preprocess the LibriSpeech dataset to ensure it is ready for training. Convert the data into the required format compatible with the QuartzNet model.
{% endstep %}

{% step %}
**Environment Setup**

Configure the environment for the QuartzNet ASR model to enable efficient fine-tuning and evaluation. Ensure all dependencies and tools are installed.
{% endstep %}

{% step %}
**Model Fine-tuning**

Fine-tune the QuartzNet ASR model on the prepared LibriSpeech data to enhance its transcription capabilities.
{% endstep %}

{% step %}
**Evaluation Process**

Assess the model's performance by calculating the Word Error Rate (WER) on a test dataset to determine its accuracy.
{% endstep %}

{% step %}
**Results Analysis**

Analyze the model's predictions and WER results to determine areas of improvement and refine the model if necessary.
{% endstep %}
{% endstepper %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.valohai.com/project-gallery/audio-and-speech/nvidia-nemo-valohai.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
