Evaluation of reading skill in third grade children using acoustic analysis

Abstract

In order to make a detailed observation of some variables in reading performance, two third grade (second series in Brazil) children were selected from a group because their performance differed widely in terms of frequency and type of silent pauses and reading aloud rate. The group was formed by 32 children from 2nd, 3rd, 4th and 5th grades. And, from an acoustic phonetic analysis of data, we were able to measure the reading aloud rate expressed in VV units per second, as well as observing performance and prosody such as: absolute frequency, duration and type of hesitant and non-hesitant silent pauses; stress group average duration; absolute frequency and duration of VV units per stress group; duration of units comprising the first vowel coming before a silent pause and the same. Statistical analysis suggests that the variable silent pause duration does not seem to differ among the children. However, some aspects like number of VV units per stress group, reading aloud rate, frequency and type of hesitant silent pauses vary a lot and may be important as parameters for reading performance.
