The Decoding of Speech in Recordings of Poor Signal to Noise Ratio

Speech intellig' Iity may be compromised by dismpted speech production.or post her: during transmission (e.g. over the telephone).recording delity.or by the capabilities of the listener (or measuring instrument).Factors affecting intelligibility include bandwidth, signal level, and the type and level of noise contamination.In decoding noise contaminated speech for forensic purposes, ltering may employed.before using contextual information as well as supraseg'mental and segmental detail to transcribe speech material.In this paper the analysis of two recordings is presented.and the decoding process discussed in relation to contextual and phonetic detail.Digital ltering improves auditory quality, but the affect on intelligibility is not assured.
