Children & Literacy
Same-language subtitles are one of the most effective tools for developing reading proficiency. Research shows they can double the chance of a child becoming a proficient reader.
The "Turn on the Subtitles" Movement
A global campaign backed by literacy researchers encourages parents to simply turn on same-language subtitles during screen time. This passive exposure maps sound to text, reinforcing reading skills without requiring extra effort. Expressive subtitles take this further by adding emotional context that deepens comprehension.
Key Research
Children who watched television with subtitles scored significantly higher on word identification and comprehension tests.
Subtitles helped children recognize, read and understand more words and make inferences about program content.
94% of children engaged with subtitles when story difficulty matched their reading level. Less fluent readers showed the greatest gains.
Safe for comprehension
A common concern with expressive subtitles is that visual changes might distract young readers. Our controlled study with 346 participants found zero comprehension penalty: quiz scores were equivalent across PHONT, standard subtitles, and no-subtitle conditions.
This means expressive subtitles can add emotional context and engagement for children without compromising the reading and comprehension benefits that make subtitles so valuable for literacy.

Sound-to-Text Mapping
Subtitles create a direct connection between spoken words and written text, accelerating the literacy learning process for developing readers.
Vocabulary Expansion
Children exposed to subtitles can better define content words, pronounce novel words, and understand context—building vocabulary naturally.
Struggling Readers Benefit Most
Research consistently shows the greatest literacy gains among children at risk of poor reading outcomes, making subtitles a powerful equity tool.
Emotional Engagement
Expressive subtitles that convey emotion help children understand narrative tone and character feelings, deepening comprehension beyond words.
