The analysis of real-world conversational signal-to-noise ratios (SNRs) can provide insight
into people's communicative strategies and difficulties and guide the development of
hearing devices. However, measuring SNRs accurately is challenging in everyday recording
conditions in which only a mixture of sound sources can be captured. This study introduces
a method for accurate in situ SNR estimation where the speech signal of a target talker in
natural conversation is captured by a cheek-mounted microphone, adjusted for free-field …
