  • Publication number: 20260038529
    Abstract: A method, apparatus, and non-transitory computer-readable medium for automatic speech recognition using conditional factorization for bilingual code-switched and monolingual speech may include receiving an audio observation sequence comprising a plurality of frames, the audio observation sequence including audio in a first language or a second language. The approach may further include mapping the audio observation sequence into a first sequence of hidden representations, the mapping being generated by a first encoder corresponding to the first language and mapping the audio observation sequence into a second sequence of hidden representations, the mapping being generated by a second encoder corresponding to the second language. The approach may further include generating a label-to-frame sequence based on the first sequence of hidden representations and the second sequence of hidden representations, using a joint neural network based model.

  • Publication number: 20050010491
    Abstract: A consolidated procurement management system includes a server (2), and a plurality of buyer systems (4) and a plurality of supplier systems (5) connected to the server through a network (3). The server includes: a material requirement information receipt module (21) for receiving material requirement information from the buyer systems; a material requirement consolidation module (22) for calculating a total requirement quantity for each material, and generating consolidated material requirement data; a quote receipt module (25) for receiving quotes from the supplier systems; a purchase module (26) for determining one or more winning suppliers from a plurality of suppliers participating in price negotiations, and for generating purchase orders; and a purchase cost allocation module (29) for calculating purchase costs and expenses for each buyer, and for generating purchase cost allocation information. A related consolidated procurement management method is also disclosed.
