论文摘要
针对儿童的语音与成人指导的语音在语言方面有所不同，例如重复，单词选择和句子长度以及语音信号本身的各个方面，例如韵律和音素变化。人类语言获取研究表明，以儿童为导向的语言有助于语言学习者。这项研究在学习直接从语音中提取语义信息时探讨了指导语音的效果。我们比较接受成人指导语音（AD）和儿童指导语音（CDS）的模型的任务性能。我们发现CD在学习的初始阶段有帮助，但最终，经过广告培训的模型达到了可比的任务性能，并更好地概括了。结果表明，这至少部分是由于两个寄存器的语言而不是声学特性，因为我们在观察接受具有声学可比的合成语音的模型时看到了相同的模式。
Speech directed to children differs from adult-directed speech in linguistic aspects such as repetition, word choice, and sentence length, as well as in aspects of the speech signal itself, such as prosodic and phonemic variation. Human language acquisition research indicates that child-directed speech helps language learners. This study explores the effect of child-directed speech when learning to extract semantic information from speech directly. We compare the task performance of models trained on adult-directed speech (ADS) and child-directed speech (CDS). We find indications that CDS helps in the initial stages of learning, but eventually, models trained on ADS reach comparable task performance, and generalize better. The results suggest that this is at least partially due to linguistic rather than acoustic properties of the two registers, as we see the same pattern when looking at models trained on acoustically comparable synthetic speech.
