• Abstract: Recent advancements in machine learning have significantly improved speech recognition, but recognizing speech from non-fluent or accented speakers remains a challenge. Previous efforts, relying on rule-based pronunciation patterns, have struggled to fully capture non-native errors. We propose two data-driven approaches using speech corpora to automatically detect mispronunciation patterns. By aligning non-native phones with their native counterparts using attention maps, we achieved a 5.7% improvement in speech recognition on native English datasets and a 12.8% improvement for non-native English speakers, particularly Korean speakers. Our method offers practical advancements for robust Automatic Speech Recognition (ASR) systems particularly for situations where prior linguistic knowledge is not applicable.

  In this article, we tackle the challenge of developing ASR systems without paired speech and text corpora. We experimentally demonstrate that an unsupervised speech recognizer can emerge from joint speech-to-speech and text-to-text masked token-infilling. This innovative model surpasses the performance of previous unsupervised ASR models under the lexicon-free setting.

  Many consumer speech recognition systems are not tuned for people with speech disabilities. We propose a query-by-example-based personalized phrase recognition system that is trained using small amounts of speech. Performance degrades as the number of phrases increases, but consistently outperforms ASR systems when trained with 50 unique phrases.

  We improve an accent-conversion model (ACM) which transforms native US-English speech into accented pronunciation. We include phonetic knowledge in the ACM training to provide accurate feedback about how well certain pronunciation patterns were recovered in the synthesized waveform. We evaluate our approach on native and non-native English datasets and found that synthetically accented data helped the ASR to better understand speech from seen accents.
