DOI: 10.1073/pnas.2117809119
Abstract: Significance More than 100 years ago, Etienne Lombard discovered that humans increase their vocal amplitude when exposed to ambient noise. Since then, the Lombard effect has gathered a plethora of interest from various disciplines ranging… read more here.

DOI: 10.1109/access.2020.3015421
Abstract: The Lombard effect is one of the most well-known effects of noise on speech production. Speech with the Lombard effect is more easily recognizable in noisy environments than normal natural speech. Our previous investigations showed… read more here.

DOI: 10.1111/jav.01564
Abstract: Signal plasticity is a building block of complex animal communication systems. A particular form of signal plasticity is the Lombard effect, in which a signaler increases its vocal amplitude in response to an increase in… read more here.
