That’s why in this article, I am gonna share 5 project topics in Natural Language Processing, that will help you to test your NLP knowledge. So without any further ado, let’s get started-

5 Project Topics in Natural Language Processing

1. Sentiment Analysis 

In natural language processing, sentiment analysis is used to interpret the sentiments and classify them as positive, negative, and neutral. Sentiment analysis is used in various domains, especially in business. Businesses are using sentiment analysis to find the opinions of their customers by using customer reviews to improve their services.

I am also using Sentiment analysis on social media posts to predict the depression level. Because Depression is a serious issue in our society and people are sharing their views on various social media platforms such as Facebook, Twitter, etc.

Many Political parties are using sentiment analysis to plan their election campaigns. So if you want to implement sentiment analysis, you can find the datasets from these websites-

3. Speech Recognition

This is the most popular application of NLP. You are aware of Google’s assistant, Amazon Alexa, Apple’s Siri, and Cortana. When you give any voice commands to them, they process with your language and try to give the best answer to your question.

In speech recognition, you can work on Recommender System for Music that analyzes audio to predict user behavior and based on user behavior suggest music. Spotify has already implemented such recommender systems to enhance their user experience. 

You can also perform the separation of audio sources that distinguish different types of audio source signals present in the midst of signals. Deep Learning can be used to perform the separation of audio sources. You can check this app as an example of the separation of audio sources.

Now, let’s see where you can find the datasets for speech recognition project-
