Hungarian Child Database For Speech Processing Applications

This is a Hungarian database containing spoken material recorded from children. The material contains Hungarian phonemes in isolated form, in sound connections, in words and in sentences.
72 children were recorded; they were aged from 5 to 10. They were not only children with good and average pronunciation, but also speech handicapped children.

Recordings were made in an anechoic room, with a Monacor ECM-100 electret microphone and a Sony TCD-D7 DAT-recorder, at the sampling rate of 48 kHz and a resolution of 16 bit. The total recording time per speaker was approximately 10-15 minutes.
Three archives were made:

- the original sound material (48 kHz, 10 CDs),
- the sample-rate-converted (22050 Hz) material with segment-markers and the extracted speech segments (4 CDs). The original material was transferred using a Turtle Beach Fiji PC sound card with digital I/O (no quality-loss).
- the sample-rate-converted, extracted speech segments on 1 CD, to be used for the subjective monitoring.

This is a valuable resource for research in speech therapy and in speech recognition.

It was compiled in the SPECO project of the INCO - Copernicus programme of European Commission, entitled "A multimedia multilingual teaching and training system for handicapped children".
