Abstract: A method for residual adapters for few-shot text-to-speech speaker adaptation includes obtaining a text-to-speech (TTS) model configured to convert text into representations of synthetic speech, the TTS model pre-trained on an initial training data set. The method further includes augmenting the TTS model with a stack of residual adapters. The method includes receiving an adaption training data set including one or more spoken utterances spoken by a target speaker, each spoken utterance in the adaptation training data set paired with corresponding input text associated with a transcription of the spoken utterance. The method also includes adapting, using the adaption training data set, the TTS model augmented with the stack of residual adapters to learn how to synthesize speech in a voice of the target speaker by optimizing the stack of residual adapters while parameters of the TTS model are frozen.

Abstract: A cartridge includes a casing, a photosensitive drum, and a coupling operatively connected to the photosensitive drum. The coupling includes a guiding portion, an engaging portion, and a visor portion. The visor portion projects outwardly in a direction perpendicular to the axis of the coupling. The visor portion covers a space downstream of the engaging portion in the rotational direction of the coupling or the visor portion is positioned upstream of the guiding portion in the rotational direction of the coupling and adjacent to the guiding portion.

Abstract: The present invention provides an optical layered body that has multiple laminated layers of which the refractive indexes are greatly different. The optical layered body can suitably prevent interfacial reflection and interference fringes attributed to the reflection in the interfaces between the layers. The optical layered body has a light-transmitting substrate, and at least an optical functional layer (1) on one surface of the substrate, wherein the refractive index of the optical functional layer (1) in the thickness direction continuously increases from the surface on the light-transmitting substrate side to the surface opposite to the light-transmitting substrate side to show a sigmoid curve.
