A Basic Introduction to Speech Recognition (Hidden Markov Model & Neural Networks)

This video provides a very basic introduction to speech recognition, explaining linguistics (phonemes), the Hidden Markov Model and Neural Networks. In short: Speech Recognition for Dummies!

00:51 - From an analog to a digital environment
04:22 - Linguistics
05:47 - Hidden Markov Model
10:54 - Artificial Neural Networks

In August 2018, we organised a workshop at our job about speech recognition. Being in charge to explain the technology behind speech recognition, we created a dynamic session where we explained the concepts both in person and via video for a good visualization. To facilitate this interaction, we created digital versions of ourselves: e-Rodi & e-Hanni. Satisfied with the feedback during the workshop, we decided to also film the parts in between to make it a full story to share online. We hope this video can help you understand speech recognition better!

Enjoy!

NB: the probabilities used in the part of the HMM (e.g. 0,6; 0,9; ...) were just chosen to explain the concept and are not a true representation of the actual probabilities.
