+# Use case APIs
+
+The directories in here are individual CMake projects to generate use case API static libraries.
+These libraries are intended to be used by external projects that only want access to the
+ready-to-use ML use case pipelines implemented in this repository. This can be as CMake projects,
+but also in the form of CMSIS-packs.
+
+## Anomaly detection
+
+This use case takes an audio clip of a machine at work as input and indicates whether there is an
+anomaly to suggest that the machine is not performing normally and might need attention.
+
+## Automatic speech recognition
+
+This use case takes in an audio clip as an input and returns a transcript of what was being said
+in text format.
+
+## Image classification
+
+This use case takes an image as input and classifies it into one of the categories the neural
+network model supports. For example, the default Mobilenet V2 based model will be able to
+classify the images into 1000 different classes.
+
+## Inference runner
+
+The inference runner is a generic use case which can run any model. It has a bigger memory
+footprint because it includes support for all possible ML operators. This use case is useful for
+checking if a given neural network model can be run with TensorFlow Lite Micro. The application
+can also be used to get performance metrics for executing the ML workload for a given model.
+
+## Keyword spotting
+
+This use case takes an audio clip as an input, divides it into smaller sub-clips, and indicates which
+keyword has been spotted for each sub-clip.
+
+## Noise reduction
+
+This use case removes noise from an audio clip. Instead of replicating a "noisy audio in" and
+"clean audio out" problem, a simpler version is defined. Given an audio clip, the use case produces
+gains to be applied to the input audio to reduce the noise.
+
+## Object detection
+
+This use case takes image data as input and performs object detection on them. The default model is
+set up to detect faces of size 20x20 and above. The output represents the coordinates of the
+bounding boxes that encapsulate the faces.
+
+## Visual wake word
+
+This use case takes images as input and determines, with a certain probability, whether the image
+contains a person.
