Figures 8.40 <strong>and</strong> 8.41 show spectrograms <strong>of</strong> <strong>the</strong> words > > > > ‘tobacco’ <strong>and</strong> ( ( ( (<br />

‘hippo’, respectively. In Figure 8.40, F3 is visible for both vowels at about 2400 Hz, its<br />

typical value for . In Figure 8.41, however, a couple <strong>of</strong> changes can be noted. First, in<br />

<strong>the</strong> initial vowel, F3 has dropped to a value <strong>of</strong> about 2250 Hz, perhaps due to <strong>the</strong><br />

influence <strong>of</strong> <strong>the</strong> nasal formant. In <strong>the</strong> second vowel, F3 is not distinguishable. Ra<strong>the</strong>r, <strong>the</strong><br />

nasal formant at 2100 Hz is visible, continuing out from <strong>the</strong> consonant into <strong>the</strong> vowel.<br />

These findings confirm that a nasal consonant does induce nasalization on<br />

adjacent vowels. Both <strong>the</strong> vowel preceding <strong>the</strong> nasal consonant <strong>and</strong> <strong>the</strong> vowel following<br />

<strong>the</strong> nasal consonant are affected.<br />
