Abstract

Concatenative synthesis is a sample-based approach to sound creation used frequently in speech synthesis and, increasingly, in musical contexts. Unit selection, a key component, is the process by which sounds are chosen from the corpus of samples. With their ability to match target units as well as preserve continuity, Hidden Markov Models are often chosen for this task, but one common criticism is its singular path output which is considered too restrictive when variations are desired. In this article, we propose considering the problem in terms of k-Best path solving for generating alternative lists of candidate solutions and summarise our implementations along with some practical examples.

A heap queue is a binary tree with the special condition that every parent has a value less than or equal to that of its children (this is a minimum queue, a maximum is naturally the inverse). The important function in our case is the push function, which adds items to the tree and maintains the sorted heap property in O(logn) time.

In fact, the system is sufficiently decoupled that any of these logical stages can be performed separately for their own purpose. For example the tool can be used solely for slicing sounds, or performing batch feature analysis on a library for the purposes of MIR.
