Reading Coach is a feature of Immersive Reader by Microsoft. Reading Coach analyzes the audio of a learner reading a passage aloud and provides specific, personalized feedback to the individual including five target words to practice. The learner is then presented with words in isolation and invited to practice reading each word aloud. To help the individual learn how to decode the word, the learner has the option turn on syllable support which places bullets between the syllables. This can help the learner how to break a word into component parts.
