Speech intelligibility estimates compress 98 MTF values into one index

Evidence

It was proposed that the modulation transfer function (MTF) be measured at seven frequency bands with fourteen modulation frequencies, resulting in 7 × 14 = 98 m values (see Figure 17.9). Ideally, the estimate of speech intelligibility should be expressed with a single value. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2422
