Why Knowby instructions have no sound

This guide explains why we prioritize text and visuals to ensure your instructions are clearer, faster, and more accessible for everyone, everywhere.

Based on Cognitive Load Theory, presenting information through both complex audio and visual video can overwhelm the brain's processing capacity.

By focusing on concise text paired with short visuals, Knowby ensures the learner isn't distracted by "extra" sensory input.

Unlike a recorded voice, text is data that can be instantly translated into over 130 languages.

This turns a local instruction manual into a global resource without the massive cost of re-dubbing audio.

Audio can be subjective. Background noise, poor recording quality, or heavy regional accents can lead to critical steps being misheard.

Text provides a "black and white" clarity that removes guesswork.

There is no need for built-in audio when modern operating systems (iOS, Android, Windows) have sophisticated Text-to-Speech (TTS) functions.

This allows the user to listen to the instructions in their preferred voice and language using tools already optimized for their specific device.

You can’t "search" a voice recording easily, but you can search text.

This makes it much faster for a user to find a specific step within a process rather than scrubbing through a video to hear a specific sentence.
