Classification: CPC G | IPC G

Claim 4:
5. The system of claim 1, wherein the output tokens are word/subword units, and wherein adaptation of the speaker-independent attention-based encoder-decoder model comprises:
initializing of an auxiliary attention-based encoder-decoder model with an encoder of the trained speaker-independent attention-based encoder-decoder model, a character-level attention network, and a character-level decoder;
training of the character-level attention network and the character-level decoder based on the input speech frames of the target speaker to minimize a character-level classification loss; and
training of the encoder of the trained speaker-independent attention-based encoder-decoder model based on the input speech frames of the target speaker to jointly minimize the word/subword unit classification loss of the trained speaker-independent attention-based encoder-decoder model and the character-level classification loss of the auxiliary attention-based encoder-decoder model.
