We’ve all heard of textual content classification, picture classification, but have you ever tried audio classification? Leave classification; there are a ton of different things we will do in audio through the use of artificial intelligence and deep learning. In this article, we’ll be talking about numerous speech processing tasks. 

You’ll be able to work on these tasks to get extra acquainted with different functions of AI within the audio and sound analysis. From audio classification to suggestion systems for music, there are numerous Tasks concepts in this list. So, let’s go.

Speech Processing Projects & Topics

1. Classify Audio

Audio classification is among the many most in-demand speech processing tasks. As deep learning focuses on building a network that resembles a human thoughts, sound recognition can also be important. Whereas picture classification has grow to be a lot superior and widespread, audio classification continues to be a relatively new concept. 

So, you possibly can work on an audio classification project and get forward of your peers with ease. You may wonder the way you’d begin working on an audio classification project, however don’t fear as a result of Google has bought your again by means of AudioSet. AudioSet is an enormous assortment of labeled audio that they collected from YouTube videos. All of them are 10-seconds lengthy and are extremely diversified. 

You should utilize the audio files present in AudioSet to train and take a look at your model. They’re appropriately labeled, so working with them is comparatively extra easy. There are presently 632 audio occasion lessons and greater than two million sound clips current in AudioSet. 

As a newbie, give attention to extracting particular options from an audio file and analyzing it by means of a neural network. You should utilize small audio clips to train the neural network. 

Extra Suggestions

Use Data Augmentation to keep away from overfitting, which might trouble you numerous whereas performing audio classification. Moreover, we suggest utilizing a convolutional neural network, also referred to as CNN, to carry out audio classification. You may additionally use slowing down or dashing up of sound to swimsuit the wants of your model. 

2. Generate Audio Fingerprints

One of the vital latest and spectacular technologies is audio fingerprinting, that’s why we’ve added it in our listing of speech processing projects. If you generate an audio sign by extracting the related acoustic features from a piece of audio, then condense the precise audio sign, we name this course of audio fingerprinting. You’ll be able to say that an audio fingerprint is a summary of a specific audio sign. They’ve the identify ‘fingerprint’ in them as a result of each audio fingerprint is unique, identical to human fingerprints. 

By producing audio fingerprints, you possibly can establish the supply of a specific sound at any occasion. Shazam might be probably the most famous example of an audio fingerprinting utility. Shazam is an app that lets folks identify songs by listening by means of a small part of the same. 

Extra Suggestions

A typical drawback in generating audio fingerprints is background noise. Whereas some folks use software program options to eliminate background noise, you possibly can strive representing audio in a distinct format and take away the pointless litter out of your file. After that, you possibly can implement the required algorithms to tell apart the fingerprints. 

3. Separate Audio Sources

One other prevalent matter amongst speech processing tasks is the separation of audio sources. In easy phrases, audio supply separation focuses on distinguishing various kinds of audio supply indicators current within the midst of indicators. You carry out audio supply separation every single day. A tough instance of audio supply separation in real-life is while you distinguish the lyrics of a song. In that occasion, you’re separating the lyrics’ audio signals from the remainder of the music. You should utilize deep learning to carry out this as effectively!

To work on this project, you should use the LibriSpeech and the UrbanNoise8k datasets. The previous is a set of audio clips of individuals studying books with none background noise, whereas the latter is a set of background noises. Utilizing each of them, you possibly can simply create a mannequin that may distinguish particular audio indicators from each other. You’ll be able to convert spectrograms to make your job simpler. 

Extra Suggestions

Keep in mind to make use of the loss function because it focuses on what half it’s a must to decrease. Utilizing the loss function, you possibly can train your model to disregard background noises with far more ease.

Segmenting refers to dividing one thing into different parts based on their options. So, audio segmentation is while you section audio indicators based on their distinctive traits. It’s a vital a part of speech processing projects, and also you’d have to carry out audio segmentation on almost the entire projects we’ve listed right here. It’s just like data cleansing but within the audio format. 

A Beginners Guide to Fundamentals of 
Natural Language Processing

A wonderful utility of audio segmentation is heart monitoring, where you possibly can analyze the sound of heartbeats and separate its two segments for enhanced analysis. One other normal utility of audio segmentation is in speech recognition, where the system can separate the phrases from background noise and improve the efficiency of the speech recognition software program.

Extra Suggestions

Here’s a superb audio segmentation challenge revealed within the MECS press. It discusses the basics of computerized audio segmentation and proposes a number of segmentation architectures for various functions. Going by means of it might actually be helpful in understanding audio segmentation better. 

5. Automated Music Tags

This project is just like the audio classification project we mentioned earlier. Nonetheless, there’s a slight distinction. Music tagging helps in creating metadata for songs so folks can discover them simply in an extensive database. In music tagging, it’s a must to work with a number of classes. So it’s a must to implement a multi-label classification algorithm. Nonetheless, as we’ve mentioned in earlier tasks, we begin with the fundamentals, aka, the audio features. 

Then we’ll use a classifier that separates the audio files based on the similarities of their options. Not like the audio classification we mentioned within the project above, we’ll have to make use of a multi-label classification algorithm right here. 

As a type of practice, it is best to begin with the Million Song Dataset, a free assortment of well-liked tracks. The dataset doesn’t have audio, and it only has options, so an intensive part is pre-done. You’ll be able to prepare and take a look at your model through the use of the Million Tune dataset easily. 

Extra Suggestions

You should utilize CNNs to work on this project. Try this case study, which discusses audio tagging intimately and makes use of Keras and CNNs for this task. 

6. Recommender System for Music

Recommender systems are broadly well-liked these days. From eCommerce to media, almost each B2C trade is implementing them to reap their advantages. A recommender system suggests services or products to a person based on their previous purchases or conduct. Netflix’s suggestion system might be probably the most famous amongst AI professionals and enthusiasts alike. Nonetheless, in contrast to Netflix’s recommendation system, your recommendation system could be analyzing audio to foretell person conduct. Music streaming platforms similar to Spotify are already implementing such recommender systems to boost person experience. 

It’s an advanced-level project which we will divide into the following sections:

  • You’ll first must create an audio classification system that may distinguish a music’s particular options from the opposite one. This system will analyze the songs our person listens to probably the most.
  • You’ll then must construct a suggestion system that analyzes these options and finds the widespread attributes amongst them. 
  • After that, the audio classification system would discover the options current in different songs our person hasn’t listened to but.
  • Upon getting these options accessible, your suggestion system would examine them with its findings and suggest extra songs based on them.

Whereas this project might sound a bit sophisticated, when you’ve constructed each models, things will get simpler. 

Extra Suggestions

A recommender system focuses on classification algorithms. For those who haven’t created one prior to now, it is best to first apply constructing one earlier than transferring onto this project. 

You can too begin with a small dataset of songs by classifying them based on the style or artist. For instance, if a person listens to The Weeknd, it’s extremely possible they’d hearken to different songs current in his genres, similar to R&B and Pop. This can allow you to shorten the database to your recommendation system. 

Learn Extra About Deep Learning

Audio analysis and speech recognition are comparatively new technologies than their textual and visible counterparts. Nonetheless, as you possibly can see on this listing, numerous implementations and prospects are current on this discipline. Thanks to artificial intelligence and deep studying, we will expect extra superior audio analysis sooner or later. 

These speech processing projects are just the tip of the iceberg. There are lots of different functions of data learning available.
