PY - 2002/09/01 Y2 - 2024/03/29 TI - Classroom acoustics for acceptable speech recognition: A review JF - Canadian Acoustics JA - Canadian Acoustics VL - 30 IS - 3 SE - Proceedings of the Acoustics Week in Canada DO - UR - https://jcaa.caa-aca.ca/index.php/jcaa/article/view/1445 SP - 42-43 AB - The basic acoustical requirements for accpetable speech recognition in classrooms were investigated. The scores for speech intelligibility increased with increasing signal-to-noise ratio until near 100% intelligibility was reached. The study was useful in determining safe teacher voice levels and the required speech/noise ratio for all ages of children. ER -
