The dataset contains audio recordings (lossless WAV) of 11 young children (age M=4.9 years old; 5 females, 6 males). Recordings include: free speech (retelling a picture book, ‘Frog, Where Are You?’ by Mercer Mayer) repeating 5 pre-defined short sentences (like 'the horse is in the stable') telling the numbers from 1 to 10 The recordings are in English and the participants include both native and non-native speakers. Each sample is recorded from 3 sources: A studio-grade microphone (Rode NT1-A) A portable microphone (Zoom H1) The two front microphones of the Aldebaran NAO robot (note that, due to technical issues, a few (sample/microphone) combinations are missing). For the free-speech recording, a manual segmentation of the utterances is provided as well.
