Query: Zero-Shot Personalized Speech Enhancement through Speaker-Informed Model
  Selection   This paper presents a novel zero-shot learning approach towards personalized
speech enhancement through the use of a sparsely active ensemble model.
Optimizing speech denoising systems towards a particular test-time speaker can
improve performance and reduce run-time complexity. However, test-time model
adaptation may be challenging if collecting data from the test-time speaker is
not possible. To this end, we propose using an ensemble model wherein each
specialist module denoises noisy utterances from a distinct partition of
training set speakers. The gating module inexpensively estimates test-time
speaker characteristics in the form of an embedding vector and selects the most
appropriate specialist module for denoising the test signal. Grouping the
training set speakers into non-overlapping semantically similar groups is
non-trivial and ill-defined. To do this, we first train a Siamese network using
noisy speech pairs to maximize or minimize the similarity of its output vectors
depending on whether the utterances derive from the same speaker or not. Next,
we perform k-means clustering on the latent space formed by the averaged
embedding vectors per training set speaker. In this way, we designate speaker
groups and train specialist modules optimized around partitions of the complete
training set. Our experiments show that ensemble models made up of low-capacity
specialists can outperform high-capacity generalist models with greater
efficiency and improved adaptation towards unseen test-time speakers.
