4. I. Audio Transcription
I. Verbatim Transcription
II. Clean Transcription
II. Speaker Identification
I. Speakers’ background
II. Speakers’ Identity
I. Timestamp codes
a. Define the number of speakers
b. Define length of their utterances.

a. Identification via voice characteristics
enrolment: the speaker's voice is recorded
and a number of features are extracted to
form a voice print, template, or model.
b. Authentication via verification
verification: speech sample or "utterance" is
compared against a previously created voice
print.
II. Speakers’ Diarisation
is the process of partitioning an input audio stream
into homogeneous segments according to the
speaker identity.

6. Corpus Annotation
Corpus annotation is the practice of adding interpretative
linguistic information to a corpus. For example, one common
type of annotation is the addition of tags, or labels, indicating
the word class to which words in a text belong.
Phonology: the rules for combining and using phonemes.
Morphology: how morphemes are used in a language.
Syntax: how words can be combined to form a sentence
Semantics: meaning of words or combinations of words.
Pragmatics: social aspects of spoken language, including
conversational exchanges.

7. TEXT ANALYTICS
Sentiment Analysis

8. LEXICON DATABASE
A lexicon database is a centralized compilation of industry-
specific terms. It serves as a guide to translation and localization
experts on how to manage key terminology.
A good terminology database will have source language key
terms and approved target language translations, along with a
clear definition and proper context for its usage. Key terms may
include acronyms, names, titles or subject specific terminology or
information. It may also include specific terms that are to be kept
in their source language.
A lexicon database is part of a suite of translation tools a
language service provider should offer, and is best used when
there is an abundance of specialised content.

9. TAXONOMY/ONTOLOGY
A taxonomy is a hierarchical classification in which things are
organized into groups or types. Taxonomy can be used to
organize and index knowledge (stored as documents, articles,
videos, etc.) such as in the form of a library classification
system, or a search engine taxonomy, so that users can more
easily find the information they are searching for.
Taxonomy various disciplines
a. Plant taxonomy (Taxonomy for Natural Science)
b. Corporate taxonymy (Business and economics)
c. Software engineering (ACM Computing Classification)
d. Bloom's taxonomy (Education and academia)
