For ESL schools & curriculum teams

Turn the coursebook you already teach from into phonics-correct listening drills.

Upload a PDF, PPTX, DOCX — or just a photo of a textbook page. Languages Lab reads every vocabulary word, example sentence and question, then renders phonics-correct, IPA-accurate audio your students practise online or completely offline. No re-typing, no re-authoring, no app for students to install.

The whole loop, in one place

Upload → extract → drill → publish.

Other tools do one slice of this. Languages Lab does the entire pipeline — so a page of your book becomes a set of drills in minutes, not an evening of copy-paste.

01
Upload

Drop in a PDF, PPTX, DOCX, or a phone photo of a page. Scanned or native — both work.

02
Extract

AI-powered OCR reads even scanned pages; a text-trust check re-reads garbled ones automatically.

03
Classify

Every item is typed — title, vocabulary, sentence, question, answer — with a review queue for anything low-confidence.

04
Drill

Phonics-correct audio in multiple modes: word-repeat, sentence-repeat, AI repeat-after-me, backchaining.

05
Publish

Share an in-app viewer, or export a self-contained HTML bundle students open from a flash drive.

Why it's different

Three things nobody else puts together.

Phonics-correct, not just “natural”.

Every consumer voice tool optimises for smooth, blended speech. We do the opposite on purpose: a strict, phonics-first speech engine with SSML, IPA <phoneme>tags and timed 500 ms breaks, so young learners hear each syllable and sound clearly. Storytelling still gets a warm, natural voice.

It teaches your book, faithfully.

We don't generate look-alike exercises from a chatbot. We extract the actual vocabulary, sentences and questions on the page you uploaded — so the audio matches exactly what you teach, and what the exam expects.

Works with no internet.

One click exports a self-contained HTML viewer with all images and audio inside it. Students open it from a USB stick or a shared folder — no login, no app, no connection. Perfect for classrooms with patchy Wi-Fi.
Universal ingestion

Bring the books you already own.

No template to fill, no content to re-create. Upload the file — or photograph the page — and Languages Lab does the reading.

  • PDF (native and scanned), PPTX, DOCX, PNG/JPG/WebP photos
  • AI-powered OCR with automatic fallback reads image-only pages
  • Per-page “text-trust” automatically re-OCRs garbled / mojibake text
  • Column-aware tables recovered as structured vocabulary rows
Coursebook upload and library
Pedagogical audio

Drills built for how children actually learn.

Not one flat “read the page” voice — a set of purpose-built practice modes, with the word lighting up in time with the audio.

  • Word-repeat, sentence-repeat, AI-chunked repeat-after-me, backchaining
  • Karaoke word-boundary highlighting synced to real speech timing
  • Adjustable speed & repeat-pause, per learner
  • Multi-voice: strict phonics voice for drills, natural voice for stories
Slide with drills and karaoke highlighting
Quality you can trust

A review queue, so nothing wrong ever ships.

Extraction is scored for confidence and quality. Anything doubtful is flagged for a quick human check — and a lesson that recovered no real content is never silently “done”.

  • Confidence-scored items route to a keyboard-fast review queue
  • Approve, edit or reject — a / e / x
  • Low-quality extractions surface as “needs review”, with one-click re-extract
  • Every AI call is metered on a per-tenant usage ledger

How we compare

Most tools do one slice. We do the loop.

We looked hard for a like-for-like competitor. The market splits into content generators, pronunciation scorers, and raw TTS — none combine your coursebook, phonics-correct drills and offline delivery.

Comparison reflects publicly-documented capabilities as of 2025–2026. Every product listed is excellent at its own slice — none does the whole pipeline.

“The lesson is already written. Languages Lab just makes it speak — correctly — and hands it to students, even where the internet doesn't reach.”
