摘要:
A system and method are described for generating semantically similar sentences for a statistical language model. A semantic class generator determines for each word in an input utterance a set of corresponding semantically similar words. A sentence generator computes a set of candidate sentences each containing at most one member from each set of semantically similar words. A sentence verifier grammatically tests each candidate sentence to determine a set of grammatically correct sentences semantically similar to the input utterance. Also note that the generated semantically similar sentences are not restricted to be selected from an existing sentence database.
摘要:
A method, an apparatus and an article of manufacture for automatic speech recognition. The method includes obtaining at least one language model word and at least one rule-based grammar word, determining an acoustic similarity of at least one pair of language model word and rule-based grammar word, and increasing a transition cost to the at least one language model word based on the acoustic similarity of the at least one language model word with the at least one rule-based grammar word to generate a modified language model for automatic speech recognition.
摘要:
A method includes deriving first information from a number of agent-customer interactions in a customer service system, and determining concurrent system activity by the agents in the customer service system, the concurrent system activity occurring at least partially concurrently with the number of agent-customer interactions. The method further includes combining the determined first information and the determined concurrent system activity to determine second information related to one or more of the number of agent-customer interactions, and outputting the second information. Apparatus and program products are also disclosed.
摘要:
Techniques for evaluating one or more spoken language skills of a speaker are provided. The techniques include identifying one or more temporal locations of interest in a speech passage spoken by a speaker, computing one or more acoustic parameters, wherein the one or more acoustic parameters capture one or more properties of one or more acoustic-phonetic features of the one or more locations of interest, and combining the one or more acoustic parameters with an output of an automatic speech recognizer to modify an output of a spoken language skill evaluation.
摘要:
Techniques, an apparatus and an article of manufacture identifying one or more utterances that are likely to carry the intent of a speaker, from a conversation between two or more parties. A method includes obtaining an input of a set of utterances in chronological order from a conversation between two or more parties, computing an intent confidence value of each utterance by summing intent confidence scores from each of the constituent words of the utterance, wherein intent confidence scores capture each word's influence on the subsequent utterances in the conversation based on (i) the uniqueness of the word in the conversation and (ii) the number of times the word subsequently occurs in the conversation, and generating a ranked order of the utterances from highest to lowest intent confidence value, wherein the highest intent value corresponds to the utterance which is most likely to carry intent of the speaker.

摘要:
According to one illustrative embodiment, a method is provided for monitoring and analyzing an office process. Information relating to desktop interaction activities of an agent and non-desktop activities of the agent are collected to form collected information. The collected information is inferred to derive delimiters relating to the desktop interaction activities and the non-desktop activities of the agent, at least one transaction performed by the agent, at least one application used by the agent, and the office process. Metrics and key performance indicators relating to a behavior of the agent, a behavior of the at least one transaction, a behavior of the at least one application and a behavior of an office process are computed to form computed information, and the collected information and the computed information are stored into a data store.
摘要:
A procedure to automatically evaluate the spoken fluency of a speaker by prompting the speaker to talk on a given topic, recording the speaker's speech to get a recorded sample of speech, and then analyzing the patterns of disfluencies in the speech to compute a numerical score to quantify the spoken fluency skills of the speakers. The numerical fluency score accounts for various prosodic and lexical features, including formant-based filled-pause detection, closely-occurring exact and inexact repeat N-grams, normalized average distance between consecutive occurrences of N-grams. The lexical features and prosodic features are combined to classify the speaker with a C-class classification and develop a rating for the speaker.
摘要:
Techniques for enabling voice access to information residing on the World Wide Web are provided. The techniques include receiving a query from a user, wherein the query comprises a voice-based request to access information residing on the World Wide Web, identifying one or more websites corresponding to the query, fetching the information from a website, wherein fetching the information comprises executing a hypertext transfer protocol (HTTP) request, organizing the information into a voice-based response and delivering the response to the user.
