  • Patent number: 12198681
    Abstract: Techniques for personalized batch and streaming speech-to-text transcription of audio reduce the error rate of automatic speech recognition (ASR) systems in transcribing rare and out-of-vocabulary words. The techniques achieve personalization of connectionist temporal classification (CT) models by using adaptive boosting to perform biasing at the level of sub-words. In addition to boosting, the techniques encompass a phone alignment network to bias sub-word predictions towards rare long-tail words and out-of-vocabulary words. A technical benefit of the techniques is that the accuracy of speech-to-text transcription of rare and out-of-vocabulary words in a custom vocabulary by automatic speech recognition (ASR) system can be improved without having to train the ASR system on the custom vocabulary. Instead, the techniques allow the same ASR system trained on a base vocabulary to realize the accuracy improvements for different custom vocabularies spanning different domains.

  • Publication number: 20240331821
    Abstract: Systems and methods for performing medical audio summarizing for medical conversations are disclosed. An audio file and meta data for a medical conversation are provided to a medical audio summarization system. A transcription machine learning model is used by the medical audio summarization system to generate a transcript and a natural language processing service of the medical audio summarization system is used to generate a summary of the transcript. The natural language processing service may include at least four machine learning models that identify medical entities in the transcript, identify speaker roles in the transcript, determine sections of the transcript corresponding to the summary, and extract or abstract phrases for the summary. The identified medical entities and speaker roles, determined sections, and extracted or abstracted phrases may then be used to generate the summary.

    Abstract: A hydraulic module is provided for a materials-handling vehicle. The hydraulic module can include a mounting frame configured to mechanically connect to a frame of the vehicle but isolate the vehicle frame from vibrations occurring in the power pack. The mounting frame supports the primary components of a hydraulic energy recovery system, including, for instance, a hydraulic tank, a hydraulic pump, and an electric motor. The hydraulic energy recovery system components can be secured to the mounting frame before the mounting frame is connected to the vehicle frame. Standardized integration components such as cables, tubes, and wiring can be used to connect the module to the electrical and hydraulic systems of the vehicle. A fluid level sensor and indicator can be provided to indicate the fluid level of the hydraulic tank. Check valves can be mounted to adapter blocks to ensure low delta pressure during operation.
