ICE-Talk 2: Interface for Controllable Expressive TTS with perceptual assessment tool

In this paper, we present open-source
(https://github.com/noetits/ICE-Talk)
tools that facilitates the use of controllable TTS systems in experiments, towards the democratization of TTS systems across domains. ICE-Talk is a web-based GUI that allows the use of a TTS system with controllable parameters via a text field and a clickable 2D plot. It enables the study of latent spaces for controllable TTS. A tool to design a perceptual experiment is provided and consists of three steps: pre-synthesizing samples covering the 2D plot representing controllable dimensions, including this interface inside a template question, and integrate it in a Mechanical Turk system called turkle.
