Abstract : The effect on speech intelligibility of varied amounts of jaw restriction and loudness levels was studied in experiments with 24 speaker and 212 listener subjects. Speech intelligibility forms were read and recorded and subsequently scored by the listeners. Results show that under the conditions of this experiment the effect of jaw restriction on speech intelligibility is negligible.
