The study trains small GPT‑2 models on child‑scale language data from dense home recordings (BabyView) and synthetic child‑directed dialogue (TinyDialogues), varying data amount, source, and diversity. Models trained on a single child’s environment predict that child’s language far better than others, a pattern largely driven by lexical and distributional factors as shown by a 5‑gram baseline. While training on multiple children improves predictions on pooled held‑out language, it does not yield a clear advantage on grammatical benchmarks, and naturalistic versus synthetic inputs produce distinct grammatical and lexical‑semantic patterns.

The paper introduces a method called randomized intermediate guidance for training tandem speech-to-speech models, where a large language model (LLM) acts as a backend providing candidate responses while the user is speaking. Instead of simulating the backend’s guidance, the approach derives guidance directly from the conversation corpus, using target responses for informative guidance and randomly sampled responses to simulate irrelevant updates. Experiments on synthetic dialogues and 3.8k hours of real conversations show that this technique yields response quality comparable to LLM-generated baselines while improving natural turn‑taking and audio‑judge naturalness.

Streaming speech-to-speech language models aim to answer spoken queries directly with synthetic speech. However, standard speech and text benchmarks do not capture whether these systems behave naturally in conversations, where timing, turn-taking, prosody, interpersonal stance, language and dialect consistency, and relationship-aware appropriateness jointly shape perceived quality.
