摘要

Accent features of an individual are always influenced by the native accent while speaking non-native language. Regional dialectal accent is always reflected as a speaker profile characteristic, which is one of the important features used to provide clues in the course of investigation through recorded speech. As a part of research on these characteristic features of regional dialectal accent, experiments have been conducted on the native accent of Chattisgarhi speakers as compared to the accent features of Khariboli speakers. Chattisgarhi is one of the popular dialects of Hindi, spoken in Chattisgrah (state province of central India). Important lexical and sentence prosodic features of speech data of 15 Chattisgarhi male speakers are studied with reference to the Khariboli speakers' speech data. Vowel quality and quantity of Chattisgarhi dialect are also distinguished from that of reference dialect. Specific acoustic features of Chattisgarhi based on the prescription model, are found unique in the characterization of speakers belonging to the regional dialectal group. Some of the accent features, in terms of intonation and tonal characteristics, are reported in the paper as speaker profiling characteristic features based on the dialectal accent and proved to be important to narrow down the field of investigation. Name of the Department Where the work was done: Central Forensic Science Laboratory, Directorate of Forensic Science, Ministry of Home Affairs, Government of India, Chandigarh-160036, India Introduction Speaker profiling includes the extraction of individual information about the anonymous perpetrator from incriminated speech material like sex, age, dialect, features of respiration, phonation, articulation and manner of speaking etc. [8]. Abberton et-al in 1978 reported in a study that a person's identity can be profiled as belonging to a regional dialectal group or categorized according to the language s/he speaks. [1]If recorded speech is available as evidence in the event where suspected culprits are not available, dialect accent of an individual plays an important role in the course of crime investigation. It carries the information related to a caller in terms of accent features. These features from recorded speech have the potential as important clue for the investigator in order to narrow down the field of investigation.A specific dialectal accent of an individual reflected in his speechis due to different uses, pronunciation, style and vocabularies used in the dialect. On the other hand, dialectal accent of a person also depends upon the educational background, mother tongue and the regional language of area where s/he is living for last many years. In India, most of the people are bilingual, especially those living in the boarder areas. In fact, the non-native language is always affected by the native dialectal accent of the person. In view of the importance of speaker profiling in the course of investigation based on the dialectal accent, studies on the accented features in terms of acoustic parameters have been conducted on some of the popular dialects of Hindi namely, Khariboli, Bhojpuri, Bundeli, Chattisgarhi, Kanauji, Marwari and Haryanvi.This research paper demonstrates and discusses the findings of the study on Chattisgarhi, which is one of the popular dialects of Hindi, spoken in the state provinces of chattisgarh by considering Khariboli as reference dialect. Some of the acoustic features based on the accent features are identified for characterization of chattisgarhi speakers as compared to the Khariboli speakers. Speech Material/ Informants A specific text has been prepared for this study containing the words commonly uttered by the criminal while committing offences like bribery, kidnapping for ransom and threatening calls etc. and it has been used for recording the speech exemplars of informants of the chosen dialects. This text has also been transliterated for Chattisgarhi dialect (uses as well
