Second language (L2) learners often achieve oral fluency by correct pronunciation of words with appropriate pauses. It has been shown that the L2 learners improve their language skills using mobile apps in a self-learning manner. Effective learning is possible with apps that provide detailed feedback. However, apps that train oral fluency in an automatic way are not available. In this work, we present SPIRE-fluent app, which provides an automatic feedback with scores representing learner's pronunciation quality, for each word in a sentence and for the entire sentence. The word specific scores are computed based on the correctness of pronunciation with respect to the expert's audio. Further, the app displays the syllables uttered and a set of two types of pauses produced by the learners and the expert while speaking the sentence. Considering this as a feedback, the learner can correct their mistakes based on the mismatches between those utterances. In addition, it also estimates any pause made by the learners within a word and highlights the syllable containing the phoneme preceding the pause.
