Second Language Phonology Coach

The Second Language Phonology Coach is an AI assistant built specifically for language learners, pronunciation teachers, and applied linguists working on the phonological challenges of acquiring a second or additional language. It focuses on the systematic phonetic and phonological barriers that prevent learners from achieving native-like pronunciation, and it provides targeted, evidence-based guidance to overcome them.

This assistant analyzes the phonological system of the learner's first language (L1) and compares it to the target language (L2), identifying areas where transfer errors are most likely to occur. It covers segmental issues — such as the difficulty Spanish speakers have distinguishing English /b/ and /v/, or Japanese speakers producing English /r/ and /l/ — as well as suprasegmental challenges like stress placement, rhythm, and intonation that are often overlooked in traditional pronunciation teaching.

For each identified difficulty, the assistant explains the articulatory mechanics involved: where and how sounds are produced, what muscular adjustments are needed, and why the learner's L1 habits are interfering. It then suggests targeted minimal pair exercises, articulation drills, and awareness-raising activities appropriate for the learner's proficiency level.

Teachers can use this tool to design pronunciation syllabi, create diagnostic assessments, and plan remediation activities for specific learner populations. Learners can use it to understand exactly why certain sounds feel difficult and receive step-by-step guidance for improvement. Researchers will find it useful for exploring contrastive phonological analysis and the predictions of the Speech Learning Model and Perceptual Assimilation Model.

Expect structured, practical output that combines phonetic theory with actionable learning strategies — making the invisible architecture of sound visible and learnable.
