PromptStyle: Controllable Style Transfer for Text-to-Speech with Natural Language Descriptions
Style transfer TTS has shown impressive performance in recent years. However,
style control is often restricted to systems built on expressive speech
recordings with discrete style categories. In practical situations, users may
be interested in transferring style by typing text descriptions of desired
styles, without the reference speech in the target style. The text-guided
content generation techniques have drawn wide attention recently. In this work,
we explore the possibility of controllable style transfer with natural language
descriptions. To this end, we propose PromptStyle, a text prompt-guided
cross-speaker style transfer system. Specifically, PromptStyle consists of an
improved VITS and a cross-modal style encoder. The cross-modal style encoder
constructs a shared space of stylistic and semantic representation through a
two-stage training process. Experiments show that PromptStyle can achieve
proper style transfer with text prompts while maintaining relatively high
stability and speaker similarity. Audio samples are available in our demo page
Calibrating the atomic balance by carbon nanoclusters
Carbon atoms are counted at near atomic-level precision using a scanning
transmission electron microscope calibrated by carbon nanocluster mass
standards. A linear calibration curve governs the working zone from a few
carbon atoms up to 34,000 atoms. This linearity enables adequate averaging of
the scattering cross sections, imparting the experiment with near atomic-level
precision despite the use of a coarse mass reference. An example of this
approach is provided for thin layers of stacked graphene sheets. Suspended
sheets with a thickness below 100 nm are visualized, providing quantitative
measurement in a regime inaccessible to optical and scanning probe methods
