The speech of eleven speakers of six languages was measured for peak energy in one-third octave bands, as compared to a reference level established by a vu meter. Levels as high as 0 dB at 10 kc, and -18 dB at 15 kc, were found. A tape speed of at least 7.5 ips is necessary to record all of the speakers without bandwidth restrictions, or level reduction.
