About ei5
About ei5.
ei5 is a diagnostic service that combines certified native English speakers and AI to evaluate your spoken English.
We measure what paper-based tests like TOEIC or Eiken can't: how your spoken English actually lands with the listener.
What we evaluate isn't just vocabulary or grammar — it's articulation, speaking rhythm, fluency, and how clearly your English comes across, assessed holistically.
Not what you said, but how it sounded.
- Certified native evaluators
- AI speech analysis
- Detailed feedback

01The Ei5 Model
The five constructs behind every ei5 test.
The ei5 Model is a framework of five evaluation constructs developed in-house to score spoken English on a consistent basis. Every ei5 test is scored on top of this shared model.
From articulation to prosody, we break what used to be loosely called "fluency" into measurable parts so we can pinpoint exactly where the message is getting lost.
FIVE CONSTRUCTS
The five things ei5 evaluates.
Phonetic Precision
Consonants and vowels articulated correctly at the phoneme level.
Fluent Articulation
Speech that flows without filler words or unnecessary pauses.
Tonal Fluidity
Pitch and stress shifting naturally so speech reads as easy to follow.
Prosodic Intonation
Stress and rhythm that carry the intended meaning to the listener.
BACKGROUND / Origin
20+ years of research
The ei5 Model was designed by linguistics specialists who have spent 20+ years in the United States researching English communication and phonetics.
Academic research distilled into criteria that learners can actually use.

From the people who took the test.
“We brought ei5 in for internal evaluation. Results land within 24 hours, fast enough to use in a high-pressure work environment. The pitch-accent detection in particular surfaced concrete things to fix that mattered in real client conversations.”

“Practicing speaking with ei5 didn't just teach me English. It built English I can actually use. I earned the top-rank ei5 Level 5 Black Belt, and this fall I'm heading to UCLA on a full scholarship. ei5 took my English to the next level and gave me both the confidence and the proof.”
