Formant warping is a human-made signal processing operation that nonlinearly maps formant frequencies between source and target vocal tracts to preserve intelligibility in voice conversion and speech synthesis. It is parameterized by a warp factor α and a frequency mapping function W(f) applied to spectral envelopes, typically implemented via filterbank warping or all-pass filter cascades. It persists through coded algorithms in speech toolkits, academic literature, and deployed voice conversion systems.

Formant warping requires a spectral representation (magnitude spectrum) to operate — it warps spectral peaks non-linearly. Remove spectral-representation and there is nothing to warp. Per Law 8 removal test: DEPENDS_ON.

Formant warping IS a signal processing technique — it nonlinearly maps formant frequencies in the spectral domain. Per Law 9: specific→general. A competent speaker calls formant warping 'a type of signal processing operation.'
