Doclair's PDF to Audio tool uses your browser's built-in speech synthesis engine, with no server, upload, or account required. Upload a text-based PDF, press play, and every word highlights in real time as it is spoken.
Most PDF-to-audio tools read text and leave you guessing where the reader is. Doclair highlights each word in amber as it is spoken — click any word to jump directly to that position. This is the same technology used in premium apps like Speechify and Natural Reader, available here for free.
Listen to NCERT textbooks, study materials, and notes hands-free while commuting, exercising, or doing housework. Set speed to 1.5× to cover more material in less time. Indian English voice is prioritised by default so pronunciation matches what you hear in class.
Screen readers read entire pages linearly. Doclair's PDF to Audio gives sighted users with reading difficulties, dyslexia, or eye strain a focused reading companion — the amber highlight draws the eye exactly to the right word, reducing cognitive load compared to plain text-to-speech.
The tool automatically detects Devanagari (Hindi, Marathi), Tamil, Telugu, and Bengali scripts and selects the appropriate voice. Indian English (en-IN) is the default for Latin-script content. Voice availability depends on your browser — Chrome on desktop has the widest selection including Google's high-quality neural voices.
