We build a CTC-based phoneme recognition model using wav2vec 2.0 (W2V2) for children under 4-year-old. We use three-level fine-tuning to gradually reduce age mismatch between adult phonetics to child phonetics.
- W2V2-Libri100h: We first fine-tune W2V2-Base using 100 hours of LibriSpeech pretrained on unlabeled 960 hours LibriSpeech adult speech corpus with IPA phone sequences.
- W2V2-MyST: We then fine-tune W2V2-Libri100h using My Science Tutor corpus (consists of conversational speech of students between the third and fifth grades with a virtual tutor).
- W2V2-Libri100h-Pro (two-level fine-tuning): We fine-tune W2V2-Libri100h using Providence corpus (consists of longititude audio of 6 English-speaking children aged from 1-4 years interacting with their mothers at home) on phoneme sequences.
- W2V2-MyST-Pro (three-level fine-tuning): Similar as W2V2-Libri100h-Pro, we fine-tune W2V2-MyST using Providence on phoneme sequences.
We show W2V2-MyST-Pro is helpful for improving children's vocalization classification task on two corpus, including Rapid-ABC and BabbleCor.
