The appearance of Congress leader Jagdish Tytler before the Central Bureau of Investigation to provide voice samples has sparked discussions and raised questions about the use of voice samples in criminal investigations.
Voice samples serve as crucial evidence in criminal cases, aiding in authentication and suspect identification.
The Collection Process and Legal Framework
When taking voice samples, investigators must acquire court approval, ensuring that proper standards are followed. Voice samples are often taken in an echo-proof environment using a voice recorder.
The individual is requested to speak a specific word or phrase from a statement already present as evidence. The collected voice sample is then compared to either an anonymous voice sample or a known voice sample, utilising international phonetic alphabets.
In India, there is no particular regulation governing the gathering and use of speech samples in criminal investigations. However, Section 53(1) of the Code of Criminal Procedure allows medical practitioners to examine accused persons at the request of a police officer.
In a divided decision in 2013, the Supreme Court maintained that collecting voice samples does not violate the basic right against self-incrimination or the right to privacy, as long as certain measures are followed.
The Difficulties and Limitations of Voice Sampling
While speech sampling has many applications, it is not without flaws and presents various obstacles. Potential errors can occur as a result of circumstances such as sickness, medicine, stress, or age, which might affect a person’s voice and hence impair the sample’s dependability.
Furthermore, the reliability of voice samples is determined by the analyst’s skill and the court’s interpretation. Concerns of privacy and dignity arise from the recording of an individual’s voice, necessitating the adoption of tight norms and regulations.
Legal Framework and the Right to Privacy
Article 21 of the Indian Constitution protects the right to privacy as a basic right. The Supreme Court’s decision in the landmark Puttaswamy v. Union of India case in 2017 recognised privacy as an intrinsic part of the right to life and personal liberty.
While this right is subject to reasonable constraints in the interests of the public good, national security, public health, and so on, the state must follow a legal procedure and guarantee justice, rationality, and proportionality.
The Significance of Jagdish Tytler’s Voice Sample Submission
The current news concerning Jagdish Tytler’s submission of voice samples emphasises the significance of voice samples in criminal investigations.
Several people were killed in the 1984 anti-Sikh riots in Delhi’s Pul Bangash district, and Tytler’s suspected participation has triggered the demand for new proof.
The CBI attempted to confirm Tytler’s voice with a specific speech he made 39 years earlier, underlining the importance of voice samples in verifying and authenticating evidence.
Summary
Voice samples are important in criminal investigations because they provide vital information and assist in the identification and authenticity of suspects.
While collecting and using voice samples presents legal and ethical concerns, the judicial system strives to find a balance between the accused’s rights and the necessity for proof.
