Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers with the main benefit of searchability. It incorporates knowledge and research in the computer science, linguistics and computer engineering fields.

Algorithms used to recognize speech
-Natural language processing (NLP):
-Hidden markov models (HMM):
-Neural Networks and Deep Neural Networks,
-PLP features:
-Viterbi search:
-Discrimination training:
-WFST framework:
-Active Learning:
-N-grams: This is the simplest type of language model (LM)
-Speaker Diarization (SD): Speaker diarization algorithms identify and segment speech by speaker identity. This helps programs better distinguish individuals in a conversation and is frequently applied at call centers distinguishing customers and sales agents.

Disclaimer: We do our best to test and make this app accurate. Due to external factors, the speech analysis results may not always be correct.
