Intelligibility of spoken Albanian language by using multimedia applications like skype and viber

Abstract

This paper intends to analyze subjective measurements of intelligibility of speech in Albanian language during the conversation between two people using applications which today is very used for communication such as Skype and Viber

Intelligibility of speech has to do with the clarity of speech that is heard, meaning of the entry of the system we have words without meaning while to the exit we mark what is heard. Speech intelligibility represents the percentage of correctly recognized words to the number of words uttered at the entrance. The measurement is done as follows: on the entry part of the transmission system sentences or words are spoken or just syllables while on receiving part is recorded what is heard; the percentage of words, sentences or syllables correctly received, on proportion to those imposed on the entry of the system, provides the percentage of intelligibility (the words, sentences or syllables).

A concrete example of why is needed digitalization of the Albanian language and why should we design models and algorithms for this is the case of Google Search by Voice, where even if you speak a word that is not clear in English language, the system finds the closest potential word and generates it.

Methods of measurements are made at different speed of the Internet, in an environment without noise and with noise, in order to see the impact on understanding of the speech with different target parameters.
