Developing a novel assistive technology, empowering the deaf to speak, using visual feedback.
Article in Journal of otology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundProfoundly deaf children beyond 5 years of age and deaf adults with no prior access to hearing have limited options to learn oral speech. They rely mainly on sign language for communication. This is because, in the absence of hearing, the brain of a deaf person is not able to process any feedback of its own speech efforts.
methodWe have developed a novel assistive technology that provides visual feedback of speech efforts to the brain of a deaf person learning to speak on a smart phone or computer, in the absence of auditory feedback. We propose that a deaf person with compensatory heightened visual processing skills, should be able to use this visual feedback to develop speech.
resultsThe first prototype of our novel assistive technology was used on 72 deaf persons (children and adults) attending deaf schools in Delhi. They progressed from speaking no sounds to about 18 sounds in 6 months.
conclusionAssistive technology using sensory substitution is a promising new approach to help deaf children and adults develop oral speech using visual feedback. More research needs to be carried out in developing this technology further.
