Children speech recording (English, spontaneous speech + pre-defined sentences)

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.
