Description:
Speech sounds are fluctuating sound signals where the composition of frequencies changes all the time.
Aperiodical overlap periodical parts. Unlike noises, some of which have similar frequency curves, sound in speech is always the carrier of meaning or of messages sent out by the speaker. Other noises like smacking of lips, hissing, rhythms, basic pitch are typical of the individual (acoustic fingerprint) but not essential for the speech content!
Information and ideas:
Supplementary to worksheets and transparencies.
Relevant for teaching:
Sound/acoustics: parameters
Vibrations and waves
Communication and understanding
