We propose a framework to address several unsolved challenges in second language (L2) automatic speaking assessment (ASA) and feedback. The challenges include: 1. ASA of visual task completion, 2. automated content grading and explanation of spontaneous L2 speech, 3. corrective feedback generation for L2 learners, and 4. all the above for a language that has minimal speech data of L2 learners. The proposed solution combines visual natural language generation (NLG), automatic speech recognition (ASR) and prompting a large language model (LLM) for low-resource L2 learners. We describe the solution and the outcomes of our case study for a picture description task in Finnish. Our results indicate substantial agreement with human experts in grading, explanation and feedback. This framework has the potential for a significant impact in constructing next-generation computer-assisted language learning systems to provide automatic scoring with feedback for learners of low-resource languages.
