• Abstract: Automated Speech Recognition shows superhuman performance for adult English speech on a range of benchmarks, but disappoints when fed children's speech. This has long sat in the way of child-robot interaction. Recent evolutions in data-driven speech recognition, including the availability of Transformer architectures and unprecedented volumes of training data, might mean a breakthrough for child speech recognition and social robot applications aimed at children. We revisit a study on child speech recognition from 2017 and show that indeed performance has increased, with newcomer OpenAI Whisper doing markedly better than leading commercial cloud services. Performance improves even more in highly structured interactions when priming models with specific phrases. While transcription is not perfect yet, the best model recognises 60.3% of sentences correctly barring small grammatical differences, with sub-second transcription time running on a local GPU, showing potential for usable autonomous child-robot speech interactions.

• Towards Unsupervised Speech Recognition Without Pronunciation Models [57.222729245842054]
  Most languages lack sufficient paired speech and text data to effectively train automatic speech recognition systems. We propose the removal of reliance on a phoneme lexicon to develop unsupervised ASR systems. We experimentally demonstrate that an unsupervised speech recognizer can emerge from joint speech-to-speech and text-to-text masked token-infilling.

• Can Language Models Learn to Listen? [96.01685069483025]
  We present a framework for generating appropriate facial responses from a listener in dyadic social interactions based on the speaker's words. Our approach autoregressively predicts a response of a listener: a sequence of listener facial gestures, quantized using a VQ-VAE. We show that our generated listener motion is fluent and reflective of language semantics through quantitative metrics and a qualitative user study.

  Children's speech recognition is a vital, yet largely overlooked domain when building inclusive speech technologies. Recent advances in self-supervised learning have created a new opportunity for overcoming this problem of data scarcity. We leverage self-supervised adult speech representations and use three well-known child speech corpora to build models for children's speech recognition.

  We propose a data augmentation technique based on the source-filter model of speech to close the domain gap between adult and children's speech. Using this augmentation strategy, we apply transfer learning on a Transformer model pre-trained on adult data. This model follows the recently introduced XLS-R architecture, a wav2vec 2.0 model pre-trained on several cross-lingual adult speech corpora.

• Accented Speech Recognition Inspired by Human Perception [0.0]
  This paper explores methods that are inspired by human perception to evaluate possible performance improvements for recognition of accented speech. We explore four methodologies: pre-exposure to multiple accents, grapheme and phoneme-based pronunciations, dropout, and the identification of the layers in the neural network that can specifically be associated with accent modeling. Our results indicate that methods based on human perception are promising in reducing WER and understanding how accented speech is modeled in neural networks for novel accents.

• Arabic Speech Recognition by End-to-End, Modular Systems and Human [56.96327247226586]
  We perform a comprehensive benchmarking for end-to-end transformer ASR, modular HMM-DNN ASR, and human speech recognition. For ASR the end-to-end work led to 12.5%, 27.5%, 23.8% WER; a new performance milestone for the MGB2, MGB3, and MGB5 challenges respectively. Our results suggest that human performance in the Arabic language is still considerably better than the machine with an absolute WER gap of 3.6% on average.

  Looking at a person's face is one of the mechanisms that humans rely on when it comes to filtering speech in noisy environments.

We propose a self-supervised reinforcement learning-based framework inspired by the early development of humans.
