Design and development a children's speech database

TL;DR

This paper details the creation of a specialized Bulgarian children's speech database designed to support speech recognition and synthesis systems, addressing age-specific speech characteristics and facilitating research in voice-controlled applications.

Contribution

It introduces a new speech database for Bulgarian children aged 4-6, including a prototype speech recognition system tailored for this demographic.

Findings

Development of a comprehensive children's speech database

Prototype speech recognition system for Bulgarian children

Facilitates research in speech recognition and synthesis for children

Abstract

The report presents the process of planning, designing and the development of a database of spoken children's speech whose native language is Bulgarian. The proposed model is designed for children between the age of 4 and 6 without speech disorders, and reflects their specific capabilities. At this age most children cannot read, there is no sustained concentration, they are emotional, etc. The aim is to unite all the media information accompanying the recording and processing of spoken speech, thereby to facilitate the work of researchers in the field of speech recognition. This database will be used for the development of systems for children's speech recognition, children's speech synthesis systems, games which allow voice control, etc. As a result of the proposed model a prototype system for speech recognition is presented.
