Blue Canoe: Our partner for mobile learning

Blue Canoe®, launched in 2016, is our game-based pronunciation learning app. Built around the Color Vowel System, Blue Canoe combines patent-pending AI and speech recognition to provide users with real-time feedback on their English pronunciation. Through daily practice activities, Blue Canoe focuses learners on word and phrase stress as the primary element of comprehensible speech and effective second language listening in English.

Blue Canoe is used by individuals, schools and companies worldwide. Request a free 2-week demo of Blue Canoe for your school or classroom.

ELTS collaborates with governmental, non-profit, and private organizations to provide teachers of English and their learners with highly effective, engaging instructional materials, training, and support.


U.S. Department of State

The U.S. Department of State’s Office of English Language Programs maintains a long-term copyright licensing agreement to make The Color Vowel® Chart accessible to teachers world-wide.

English teachers outside the U.S. can request full-color posters of The Color Vowel Chart through their Regional English Language Officer via U.S. embassies and consulates. This laminated poster comes with detailed instructional notes on the back side. As of August 2018, over 10,000 posters of the Color Vowel Chart have been distributed to English teachers around the world.

To further support English language teachers in their effective use of the Color Vowel Chart, ELTS delivered a live 70-minute webinar to over 1,600 participants through the Office of English Language Programs.

If you teach English outside the US, visit the American English website and contact your Regional English Language Officer (RELO) to request materials.

Intercambio Uniting Communities

Intercambio and ELTS have been collaborating since 2014 to include the Color Vowel Chart in Intercambio’s textbook series, Interactive English. This special collaboration puts the Color Vowel Chart into the hands of thousands of ESL teachers, tutors, and adult English language learners across the United States as part of a high-quality, affordable curriculum that addresses the needs of adult immigrants and their families.

Intercambio’s Executive Director, Lee Shainis, made a radical decision for the textbook series, replacing its conventional, alphabetized glossary with a Color-Vowel-coded word list featuring the words in the order they appear by chapter. Now instead of having to navigate phonetic transcriptions, learners simply see “student – BLUE,” making for a simple glossary that powerfully guides the learner speak with confidence.

U.S. Peace Corps

In 2014, ELTS developed a 6-hour training as part of the new Peace Corps TEFL Certification program. The modules, which focus on the teaching of pronunciation, include the Color Vowel™ Chart and its accompanying multi-modal teaching methods as a way of providing new teachers and their students with an effective, accessible, practical, tool for learning new vocabulary and mastering spoken English.

The Peace Corps TEFL Certificate is currently offered to Peace Corps Volunteers in Albania, Armenia, Benin, Costa Rica, Ecuador, Kyrgyz Republic, Madagascar, Moldova, Nicaragua, Rwanda, and Thailand.

Washington Literacy Center

Washington Literacy Foundation logoELTS has been working with the Washington Literacy Center since 2017 to develop innovative brain-based literacy interventions for adults who have speech difficulties, low-literacy and/or dyslexia. WLC serves adult learners, including native English speakers and English language learners.

Hindu American Foundation

Hindu American Foundation logoELTS recently collaborated with the Hindu American Foundation to develop a lesson tool kit for Grade 4-6 classrooms to promote familiarity with Hindu culture and the Hindu celebration of Holi. By integrating the Color Vowel Approach into the Holi Kit, teachers and children are provided with a clear, effective strategy for pronouncing and using new vocabulary that appear in three folktales that form the cornerstone of the lesson. The Holi Kit became available in Spring of 2019.
