The data is clear: accessibility isn't a niche — it's a massive, underserved audience. Here are the numbers that should make every streamer take accessibility seriously.
Make Your Stream Accessible466 million people worldwide have disabling hearing loss, according to the World Health Organization (WHO, 2021). That's roughly 5% of the global population. By 2050, the WHO projects this number will reach 900 million as populations age.
15% of US adults — approximately 37.5 million Americans — report some degree of hearing difficulty, according to the National Institute on Deafness and Other Communication Disorders (NIDCD). This includes the full spectrum from mild difficulty to profound deafness.
2-3 million Americans are deaf (little or no hearing), and roughly 28 million Americans are hard of hearing. These communities are active participants in gaming and streaming culture — and the majority of gaming streams they encounter have no captions. For streamers: if your stream is accessible via captions, you're serving a community that most streamers ignore entirely.
World Health Organization data. 5% of the global population. Growing to 900M by 2050. A massive, underserved streaming audience that follows accessible creators.
Facebook's own research shows 85% of their video is watched muted. On autoplay mobile feeds, silence is the default. Captions turn passive scrollers into active viewers.
Over 1.5 billion people speak English as a second language. Non-English-native gaming markets in Brazil, Japan, Korea, and Germany are enormous. Translation captions reach them all.
Beyond the raw audience size numbers, captions have measurable impact on the engagement metrics that drive platform algorithms.
Video completion rates increase with captions. Multiple studies across YouTube, Facebook, and LinkedIn show that captioned videos have 12-40% higher completion rates than uncaptioned videos of the same length. Viewers who can follow content without audio stay longer — and completion rate is a direct input into algorithmic distribution.
Mobile viewing is predominantly silent. Facebook's internal research found that 85% of video on their platform is watched without sound. A 2016 Verizon and Publicis Media study found that 69% of people watch mobile video in public places with the sound off. For streamers hoping to reach audiences on mobile devices, captions are the difference between a viewer and a bounce.
International market reach matters enormously. Over 1.5 billion people worldwide speak English as a second or foreign language (British Council, 2020). StreamTranslate's 125-language translation directly converts this statistic into accessible viewership — turning unreachable international audiences into followers.

Research shows that 85% of Facebook video and 69% of Instagram video is watched without sound. On mobile platforms with autoplay, the majority of initial video views occur in silence. Captions directly improve engagement for this enormous segment.
Yes. Studies show captions increase average view duration by 12-40% depending on the platform and content type. More viewers stay longer when they can follow content without sound — directly improving algorithm signals.
Over 1.5 billion people speak English as a second language. The majority of internet users are non-native English speakers. Translation captions remove the language barrier for this enormous global audience.
