TonePerfect English Pronunciation Checker
TonePerfect English Pronunciation Checker records the learner reading five short words in the browser and returns a score for every individual sound, grouped by syllable, with an articulation instruction for each one. The engine covers the forty one English phonemes and was validated against the ratings of human pronunciation experts on a public research corpus. A sound library, a placement test and short daily sessions are part of the course.
Limits of the Free Tier Plan: the five word test runs in the browser with no account, and the free plan keeps at least one guided practice session a day, the daily workout, the placement test and progress tracking. Unlimited assessments, spaced repetition reviews, practice on text of your own and the advanced analytics belong to the paid Premium plan.
How It Helps Your Business English
The page opens with the five word recording test and explains that the engine scores each sound inside each word rather than the word as a whole. A chart of the English sounds that most often give learners trouble follows, giving the tongue and lip position for each one, the substitution usually heard and example words, then the plans and a question and answer section.
You read five short words into your microphone and receive a score for each sound you produced, so you learn which ones to work on first rather than guessing. The note under each sound tells you where to place your tongue and lips to correct it, and the sound chart lets you return to a single sound and drill it as often as you need.
