It is the study of how to convert one’s voice to soun d like that of another without changing the linguistic content. Voice conv ersion belongs to a general technical field of speech synthesis\, which co nverts text to speech or changes the properties of speech\, for example\, voice identity\, emotion\, and accents. Voice conversion involves multiple speech processing techniques\, such as speech analysis\, spectral convers ion\, prosody conversion\, speaker characterization\, and vocoding. With t he recent advances in theory and practice\, we are now able to produce hum an-like voice quality with high speaker similarity. In this talk\, Dr. Sis man will present the recent advances in voice conversion and discuss their promise and limitations. Dr. Sisman will also provide a summary of the av ailable resources for expressive voice conversion research.\nBiography\nDr .

Prev enting natural or man-made disasters requires being aware of these pattern s and taking pre-emptive action to address and reduce them\, or ideally\, eliminate them. Emerging events\, such as the COVID pandemic and the Ukrai ne Crisis\, require a time-sensitive comprehensive understanding of the si tuation to allow for appropriate decision-making and effective action resp onse. Automated generation of situation reports can significantly reduce t he time\, effort\, and cost for domain experts when preparing their offici al human-curated reports. However\, AI research toward this goal has been very limited\, and no successful trials have yet been conducted to automat e such report generation and “what-if” disaster forecasting. Pre-existing natural language processing and information retrieval techniques are insuf ficient to identify\, locate\, and summarize important information\, and l ack detailed\, structured\, and strategic awareness.
