Image Recognition:

One of the most common applications of machine learning is image recognition. It is used to recognize objects, people, places, digital images, and so on. Automatic friend tagging suggestion: This is a popular use case for image recognition and face detection.

Facebook offers an auto friend tagging suggestion feature. When we upload a photo with our Facebook friends, we automatically get a tagging suggestion with their names, which is powered by machine learning's face detection and recognition algorithm.

It is based on the Facebook project "Deep Face," which is in charge of face recognition and person identification in images.

Recognition of Speech

When we use Google, we have the option to "Search by voice," which falls under speech recognition and is a popular machine learning application.

Speech recognition, also known as "Speech to text" or "Computer speech recognition," is the process of converting voice instructions into text. Machine learning algorithms are currently widely used in a variety of speech recognition applications. Google Assistant, Siri, Cortana, and Alexa use speech recognition technology to respond to voice commands.
