Exploring Universal Attribute Characterization of Spoken Languages for Spoken Language Recognition

Outline Introduction UAR-FrondEnd VSM-BackEnd Experiment

Introduction Here we focus on the token-based. Propse an alternative universal acoustic characterization of spoken languages based on acoustic phonetic feature. The advantage of using attribute-based unit is they can be define universally across all language.

System Overview

UAR-FrondEnd The frond-end processing module tokenize all spoken utterances into sequences of speech unit using a universal attribute recognizer. Two phoneme-to-attribute table are created that are phoneme-to-manner and phoneme-to-place.

VSM-BackEnd Each transcription is converted into a vector-based representation by applying LSA.

Experiment The OGI-TS corpus is used to train the articulatory recognizer. This corpus has phonetic transcriptions for six language.

Experiment CallFriend corpus is used for training the back-end language models. Test are carried out on the NIST 2003 spoken language evaluation material.
