Mysore, Dec 17(UNI) Central Forensic Science Laboratory Chandigarh, Assistant Director Dr S K Jain today emphasised the important role of forensic investigation in the detection of crimes in the country.

Speaking after inaugurating a four-day National Workshop on "Forensic Voice Identification" organised by the All India Institute of Speech and Hearing (AIISH) here, he said that the country was virtually shaken by the recent cases of match fixing, Parliament attack and Tehelka. Forensic Science Laboratories have to prepare themselves to deal with huge amount of voice samples and also voice of any language, in any mode and with any environmental effects.

He said that these days the voice has acquired unusual significance in the investigation of criminal cases, as most of the police officers have learnt the use of latest technology to tape the voices of the suspects during the commission of crimes. However, it was the scientific analysis of the voice which would provide conclusive proof to link the suspect with the crime.

A lot of development has taken place in the area of speech science, but still scientific achievements are required to be taken to the heights, so as to develop software and matching hardware, which could make possible the analysis of very subtle parameters of voice like the way child recognizes the voice of his mother, he added.

Dr Jain called upon the delegates to deliberate in knowing about the acoustic, phonetic, speech enhancement, vocal anatomy and organ of speech and advanced computer approaches for analysis of audio sample.

AIISH, Director Dr Vijayalakshmi Basavaraj, speaking on the occasion said that the Institute has sent a proposal to the Mysore University for according affiliation to start two new Diploma courses in clinical linguistics for speech pathology and forensic voice science technology.

About one hundred delegates from all over the country are attending the workshop.
