Automatic Pronunciation Assessment -- A Review

Pronunciation assessment and its application in computer-aided pronunciation training (CAPT) have seen impressive progress in recent years. With the rapid growth in language processing and deep learning over the past few years, there is a need for an updated review. In this paper, we review methods employed in pronunciation assessment for both phonemic and prosodic. We categorize the main challenges observed in prominent research trends, and highlight existing limitations, and available resources. This is followed by a discussion of the remaining challenges and possible directions for future work.Comment: 9 pages, accepted to EMNLP Finding

Perception of English Prominence by Native Mandarin Chinese Speakers

Native-like perception of intonational prominence is important for spoken language competency. Non-native speakers may have trouble interpreting prosodic variation in a second language like English, where intonational variation can critically influence utterance semantics. By identifying types of prosody non-native learners find difficult to perceive, we can improve our ability to teach L2 speakers a language. In this paper we present results of a perception study in which Mandarin speakers with knowledge of English were tested on their ability to identify prosodic prominence in English in a variety of contexts. Through this analysis we identify particular contexts which make it difficult for Mandarin speakers to recognize pitch accent in English

La liaison dans un corpus d’apprenants : Le projet « Interphonologie du Français Contemporain » (IPFC)

Ce chapitre présente le projet « Interphonologie du français contemporain » (IPFC), qui vise à constituer et analyser une large base de données de français langue étrangère produit par des apprenants de diverses L1. Nous illustrons ensuite la méthodologie adoptée dans le projet à travers le phénomène de la liaison. Après avoir exposé les enjeux de la liaison pour le français L2, nous présentons une étude préliminaire des réalisations de liaisons par des apprenants hispanophones et japonophones en lecture de texte et montrons en quoi le projet IPFC est susceptible de fournir des données diversifiées en termes d’apprenants et de tâches, ce qui devrait, à terme, permettre un renouvellement des données pour l’enseignement de la liaison en français L2.In this chapter, we present the project “Interphonology of Contemporary French” (IPFC). The aim of the project is to constitute and analyse a large database of L2 French, produced by learners of different origins. The methodology adopted in the project is then illustrated through the phenomenon of liaison. First we describe the challenges of liaison for L2 French learners and then we present a preliminary study of the realisations of liaison produced by Spanish and Japanese learners of French in the text reading task. We conclude by showing that the IPFC project provides an adequate framework to deepen our knowledge of L2 liaison, which in turn should help us to renew the pedagogical material used to teach liaison in L2 French
