Fundamental Frequency Variation (FFV): A Normative Implementation in C

The FFV representation is an instantaneous-frame representation of variation in fundamental frequency, and is intended to indirectly model (at a sub-unit level) intonation trajectories, in the same way that standard MFCC features indirectly model formant trajectories at the sub-unit level. The representation was developed with Jens Edlund and Mattias Heldner at the Department of Speech, Music and Hearing at KTH. Code which wraps ffv-1.x.x for use in existing signal processing environments includes:

The FFV representation was introduced in

and an overview is available in

Several computational refinements are described in

Demonstrations of inferred model structure over the representation are available in

Finally, application of the FFV representation to speaker recognition is described in
