  • Publication number: 20230351098
    Abstract: Solutions for custom display post processing (DPP) in speech recognition (SR) use a customized multi-stage DPP pipeline that transforms a stream of SR tokens from lexical form to display form. A first transformation stage of the DPP pipeline receives the stream of tokens, in turn, by an upstream filter, a base model stage, and a downstream filter, and transforms a first aspect of the stream of tokens (e.g., disfluency, inverse text normalization (ITN), capitalization, etc.) from lexical form into display form. The upstream filter and/or the downstream filter alter the stream of tokens to change the default behavior of the DPP pipeline into custom behavior. Additional transformation stages of the DPP pipeline perform further transforms, allowing for outputting final text in a display format that is customized for a specific user. This permits each user to efficiently leverage a common baseline DPP pipeline to produce a custom output.

  • Publication number: 20230352009
    Abstract: Systems generate segments of spoken language utterances based on different sets of segmentation boundaries. The systems are also configured to generate one or more formatted segments by assigning a punctuation tags at segmentation boundaries and to generate one or more final sentences from the one or more segments.

  • Publication number: 20180330725
    Abstract: A method for priming an extensible speech recognition system comprises receiving audio language input from a user. The method also comprises receiving an indication that the audio language input is associated with a first language-based intelligent agent. The first language-based intelligent agent is associated with a first grammar set that is specific to the first language-based intelligent agent. Additionally, the method comprises matching one or more spoken words or phrases within the audio language input to text-based words or phrases within a general grammar set associated with a speech recognition system and the first grammar set. The first grammar set is associated with a higher match bias than the general grammar set, such that the speech recognition system is more likely to match the one or more spoken words or phrases to the text-based words or phrases within the first grammar set.

  • Patent number: 9460081
    Abstract: Examples of the present disclosure describe generation of a multi-arc confusion network to improve, for example, an ability to return alternatives to output generated. A confusion network comprising token representations of lexicalized hypotheses and normalized hypotheses is generated. Each arc of the confusion network represents a token of a lexicalized hypothesis or a normalized hypothesis. The confusion network is transformed into a multi-arc confusion network, wherein the transforming comprising realigning at least one token of the confusion network to span multiple arcs of the confusion network. Other examples are also described.

  • Patent number: 8332765
    Abstract: A system for reporting and analyzing problems encountered by computer users. The system includes a recording tool executing on a user computer to capture a sequence of user interactions in the context of a graphical user interface. When a problem or other stop event is encountered, the tool generates a report indicating user interactions leading to the stop event, including information such as the specific sequence of controls for specific programs accessed by the user. The report can be analyzed to identify a sequence of user interactions characteristic of a problem type, which in turn may be used to find a solution for a particular user's problem. The system may also include a server that receives and analyzes reports from multiple computer users to identify patterns of user interactions that characterize problem types. This information may be used for associating specific problems with future reports or to improve products.
