An onomatopoeic word, which is a character sequence that phonetically imitates a sound, is effective in expressing characteristics of sound such as duration, pitch, and timbre. We propose an environmental-sound-extraction method using onomatopoeic words to specify the target sound to be extracted. B…

We propose an audio-visual speech enhancement (AVSE) method conditioned both on the speaker’s lip motion and on speaker-discriminative embeddings. We particularly explore a method of extracting the embeddings directly from noisy audio in the AVSE setting without an enrollment procedure. We aim to im…
