Build vocabulary and perfect pronunciation with 14,829 words organized into five levels. The ladder is anchored in CEFR-J (A1–B2) for global proficiency bands, and the upper bands also incorporate China CET-4 / CET-6 and GRE / TOEFL vocabulary tags from the dictionary — so you can drill pronunciation in the same buckets that many learners use for CET-4/6 and exam prep for studying abroad.
CEFR-J five bands + CET-4 / CET-6 + GRE / TOEFL
CEFR-J (Common European Framework — Japanese profile, TUFS) supplies the A1→B2 progression. CET-4 and CET-6 lists, plus GRE and TOEFL tags, come from the open ECDICT dataset and are merged into the levels below. Together they give a single practice path from everyday English to exam-heavy vocabulary:
- Level 5 (CEFR-J A1) — Beginner: most common words for basic communication (free)
- Level 4 (CEFR-J A2) — Elementary: high-frequency words for everyday use (partially free)
- Level 3 (CEFR-J B1 + CET-4) — Intermediate: B1 band plus CET-4 (College English Test Band 4) vocabulary (Pro)
- Level 2 (CEFR-J B2 + CET-6) — Upper-intermediate: B2 band plus CET-6 (College English Test Band 6) vocabulary (Pro)
- Level 1 (GRE + TOEFL) — Advanced: words tagged GRE and/or TOEFL for academic and test prep (Pro)

Word Link — Smart Grouping for Better Retention
Words are not presented in random or alphabetical order. Instead, SoundsRight uses an intelligent Word Link system powered by deep learning word embeddings to group and order words in your practice sequence:
- Related by meaning — e.g. apple, orange, banana (fruits together)
- Same word class — e.g. I, you, he, she (pronouns together)
- Shared prefix or suffix — words with the same root, e.g. un- (unhappy, unfair), -tion (action, decision)
Deep learning word embeddings group related words together for better retention.
