Language learning strategies have become an important element of second language acquisition research over the course of the last few decades. Much research on these strategies has been dedicated to speaking, reading, and other language skill sets. However, one essential skill needed for communication is pronunciation. No matter how proficient other areas of linguistic ability may be, it can be difficult to interact effectively with native speakers if one's pronunciation is poor. Yet research dedicated to pronunciation and language learning strategies is in surprisingly short supply. Of those studies that have researched pronunciation strategies, some have been dedicated to discovering new pronunciation strategies (Derwing & Rossiter, 2002; Osburne, 2003; and Vitanova & Miller, 2002), while others (Peterson, 2000) categorized pronunciation strategies using a well known strategy inventory. However, there is one study that has gone in a different direction concerning pronunciation strategies. Rather than categorize pronunciation strategies using a strategy taxonomy like Oxford (1990), Eckstein (2007) categorized pronunciation strategies using Kolb's (1984) Experiential Learning Cycle model and found significant effects between pronunciation accuracy and use of pronunciation strategies mapped using Eckstein's (2007) Pronunciation Acquisition Construct (PAC).The present study tested the PAC by teaching pronunciation strategies to L2 Japanese learners. The aim of the current study was to examine the effect of pronunciation strategy usage categorized using the PAC upon pronunciation gains and to examine learner differences based upon pronunciation gains and strategy usage. In doing so, significant gains were found in contextualized pronunciation. Additionally, subjects who more frequently used the strategy "think of benefits to be gained by improving pronunciation", a motivation strategy, were found to show higher levels of pronunciation gain in a non-contextualized pronunciation environment.

In the last thirty years, language learning strategies have been used in the field of English as a Second Language (ESL) to help learners autonomously improve their English listening, speaking, reading, and writing. However, language learning strategies have not been applied to pronunciation learning in a large scale manner. This study attempted to bridge this gap by investigating the usage of pronunciation learning strategies among adult ESL learners. A strategic pronunciation learning scale (SPLS) was administered to 183 adult ESL learners in an Intensive English Program. Their scores on the SPLS were compared with their scores of spontaneous pronunciation on a program-end speaking assignment. A stepwise regression analysis showed that frequently noticing other's English mistakes, asking for pronunciation help, and adjusting facial muscles all correlated significantly with higher spontaneous pronunciation skill. Other analyses suggested that strong pronunciation learners used pronunciation learning strategies more frequently than poorer learners. Finally, a taxonomy is proposed that categorizes pronunciation learning strategies into pedagogically-founded groups based on Kolb's (1984) learning construct and four stages of pronunciation acquisition: input/practice, noticing/feedback, hypothesis forming, and hypothesis testing. This taxonomy connects language learning strategies to pronunciation acquisition research.
