- Abstract: The integration of natural language processing (NLP) technologies into
educational applications has shown promising results, particularly in the
language learning domain. Recently, many spoken open-domain chatbots have been
used as speaking partners, helping language learners improve their language
skills. However, one of the significant challenges is the high word-error-rate
(WER) when recognizing non-native/non-fluent speech, which interrupts
conversation flow and leads to disappointment for learners. This paper explores
the use of GPT4 for ASR error correction in conversational settings. In
addition to WER, we propose to use semantic textual similarity (STS) and next
response sensibility (NRS) metrics to evaluate the impact of error correction
models on the quality of the conversation. We find that transcriptions
corrected by GPT4 lead to higher conversation quality, despite an increase in
WER. GPT4 also outperforms standard error correction methods without the need
for in-domain training data.

This paper investigates the application of GPT-3.5 for Grammatical Error Correction (GEC) in multiple languages.
We conduct automatic evaluations of the corrections proposed by GPT-3.5 using several methods.
For English, GPT-3.5 demonstrates high recall, generates fluent corrections, and generally preserves sentence semantics.
But, human evaluation for both English and Russian reveals that, despite its strong error-detection capabilities, GPT-3.5 struggles with several error types.

This paper investigates the role of correction in the context of large language models by conducting two experiments.
The first experiment focuses on correction as a standalone task, employing few-shot learning techniques with GPT-like models for error correction.
The second experiment explores the notion of correction as a preparatory task for other NLP tasks, examining whether large language models can tolerate and perform adequately on texts containing certain levels of noise or errors.
