Figure 2.

Spectrographic example of utterance with loft regime preceded and followed by modal. Total frequency range is approximately 3.5 kHz. Although some evidence of more complex harmonic structure is visible in the transition from loft back to modal, the episode is shorter than 50 ms and so is not classified as a distinct regime (spurious appearances of transitional overlap are also the unavoidable result of the temporal smearing in extreme narrowband spectrograms).
