Speech Emotion Recognition with
librosa
Speech emotion recognition,
the best ever python mini project. The best example of it can be seen at call
centers. If you ever noticed, call centers employees never talk in the same
manner, their way of pitching/talking to the customers changes with customers.
Now, this does happen with common people too, but how is this relevant to call
centers? Here is your answer, the employees recognize customers’ emotions from
speech, so they can improve their service and convert more people. In this way,
they are using speech emotion recognition. So, let’s discuss this project in
detail.
What is Speech Emotion Recognition?
Speech Emotion Recognition,
abbreviated as SER, is the act of attempting to recognize human emotion and
affective states from speech. This is capitalizing on the fact that voice often
reflects underlying emotion through tone and pitch. This is also the phenomenon
that animals like dogs and horses employ to be able to understand human
emotion.
SER is tough because emotions are
subjective and annotating audio is challenging.
What is librosa?
librosa is a Python
library for analyzing audio and music. It has a flatter package
layout, standardizes interfaces and names, backwards compatibility, modular
functions, and readable code. Further, in this Python mini-project, we
demonstrate how to install it (and a few other packages) with pip.
What is JupyterLab?
JupyterLab is an open-source,
web-based UI for Project Jupyter and it has all basic functionalities of the
Jupyter Notebook, like notebooks, terminals, text editors, file browsers, rich
outputs, and more. However, it also provides improved support for third party
extensions.
To run code in the JupyterLab,
you’ll first need to run it with the command prompt:
