Voiceless laterals are relatively rare cross-linguistically, with Angami being an exception where they exhibit aspirated characteristics. This investigation delves into the distinctive traits of both voiced and voiceless laterals in the language, which are produced in three contexts. The result of the study showed that there is a clear distinction between voiced and voiceless laterals, and the acoustic-phonetic properties that are significant in voicing distinction are formants (F1- F2), Harmonics to Noise Ratio (HNR), and amount of voicing. The study also shows that voiceless laterals differ in the contexts in which they are spoken. Statistical analyses provide further support for the observed distinctions.
