This paper reports the results of two experiments investigating the effects on speech acoustics and intelligibility of a number of different types of forensically-relevant fabric mouth and face coverings, including the niqāb (full-face Muslim veil), balaclava, and surgical mask. For the perceptual (intelligibility) experiment, subjects were presented with two types of speech stimuli, ‘bimodal’ and ‘unimodal’, and asked to write down what they heard. Four facial guises were used (niqāb…

Effects of forensically-realistic facial concealment on auditory-visual consonant recognition in quiet and noise conditions
TLDR
Investigating auditory-only and auditory-visual consonant recognition where the talker’s face is obscured by various types of face-concealing garments and headgear revealed a significant AV effect, however, the strength of the effect varied considerably as a function of facewear type.
The impact of face-concealing garments on the acoustics of fricatives.
The study reported here is part of a larger project which examines multimodal speech and speaker recognition in a forensic context, both from a human and an automatic perspective. It builds on pilot…
Effects of forensically-relevant facial concealment on acoustic and perceptual properties of consonants
This thesis offers a thorough investigation into the effects of forensically-relevant facial concealment on speech acoustics and perception. Specifically, it explores the extent to which selected…
Effect of Mouth Mask and Face Shield on Speech Spectrum in Slovak Language
TLDR
Different face masks are compared in terms of their acoustic filtering effect, measured by placing the mask on an artificial head/mouth simulator, and it was found that when wearing a mask, people tend to slightly increase their voice level, while when wearing plastic face shield, they reduce their vocal power.
How Face Masks Interfere With Speech Understanding of Normal-Hearing Individuals: Vision Makes the Difference
TLDR
The speaker's use of face masks leads to a significant deterioration of speech understanding by the normal-hearing listener, and the data suggest that these effects may play a role in many everyday situations that typically involve noise.
Acoustic characteristics of fricatives, amplitude of formants and clarity of speech produced without and with a medical mask.
TLDR
It appeared from the findings in this study that these masks only affected fricative consonants and did not affect vowel production, and poorer speech clarity in these mask-wearing conditions has important implications for speech perception in communication between clinical staff and patients in clinics, and between people in everyday situations.
The Effects of Forensically Relevant Face Coverings on the Acoustic Properties of Fricatives
This forensically motivated study investigates the effects of a motorcycle helmet, balaclava, and plastic mask on the acoustics of three English non-sibilant fricatives, /f/, /θ/, and /v/ in two…
Analysis of Face Mask Effect on Speaker Recognition
TLDR
The target is to separate the effect of muscle constriction and increased vocal effort in speech produced under face mask from sound transmission and radiation properties of face mask.
Speaking under Cover: The Effect of Face-concealing Garments on Spectral Properties of Fricatives
TLDR
Preliminary results of a spectral analysis of voiceless fricatives, taken from a subset of speakers, are presented and possible articulatory, acoustic and perceptual effects of the masks in a forensic context are introduced.
Face Masks Impact Auditory and Audiovisual Consonant Recognition in Children With and Without Hearing Loss
Teachers and students are wearing face masks in many classrooms to limit the spread of the coronavirus. Face masks disrupt speech understanding by concealing lip-reading cues and reducing…

Hearing lips and seeing voices
TLDR
The study reported here demonstrates a previously unrecognised influence of vision upon speech perception, on being shown a film of a young woman's talking head in which repeated utterances of the syllable [ba] had been dubbed on to lip movements for [ga].
The Use of Auditory and Visual Information in Phonetic Perception
Although speech perception is usually considered an auditory process, studies have shown that visual information provided by the movements of a talker’s mouth and face strongly influences what an…

TLDR
Optical distortion seems to have potential as an auditory training technique to shift attention of hearing-impaired observers to non-dominant acoustic cues during A-V perception of speech.
Visual contribution to speech intelligibility in noise
Oral speech intelligibility tests were conducted with, and without, supplementary visual observation of the speaker's facial and lip movements. The difference between these two conditions was…

Attention to facial regions in segmental and prosodic visual speech perception tasks.
TLDR
The results indicate that information in the upper part of the talker's face is more critical for intonation pattern decisions than for decisions about word segments or primary sentence stress, thus supporting the Gaze Direction Assumption.

Acoustic-phonetic characteristics of speech produced in noise and while wearing an oxygen mask.
TLDR
In addition to the expected changes of increased pitch and amplitude associated with speaking in noise without an oxygen mask, significant effects were found (particularly in the formant center frequencies) as a result of using the oxygen mask.
Gradient and Visual Speaker Normalization in the Perception of Fricatives
TLDR
Listeners’ responses to prototypical and non—prototypical male and female speech with their responses to audio—visual integrated stimuli in the fricatives [sj (“sod”) and [I] in Ohio English suggest that the speaker’s sex affects perception of fricative in a “gradient” manner.
