Automatically providing a user with substitutes for potentially ambiguous user-defined speech commands

Номер: US20120095765A1
Автор: James R. Lewis, Leslie R. Wilson, William K. Bodin
Принадлежит: Nuance Communications Inc

A method for alleviating ambiguity issues of new user-defined speech commands. An original command for a user-defined speech command can be received. It can then be determined if the original command is likely to be confused with a set of existing speech commands. When confusion is unlikely, the original command can be automatically stored. When confusion is likely, a substitute command that is unlikely to be confused with existing commands can be automatically determined. The substitute can be presented as an alternative to the original command and can be selectively stored as the user-defined speech command.

A method is disclosed for applying a multi-state barge-in acoustic model in a spoken dialogue system. The method includes receiving an audio speech input from the user during the presentation of a prompt, accumulating the audio speech input from the user, applying a non-speech component having at least two one-state Hidden Markov Models (HMMs) to the audio speech input from the user, applying a speech component having at least five three-state HMMs to the audio speech input from the user, in which each of the five three-state HMMs represents a different phonetic category, determining whether the audio speech input is a barge-in-speech input from the user, and if the audio speech input is determined to be the barge-in-speech input from the user, terminating the presentation of the prompt.

Принадлежит: Nuance Communications Inc

The present solution includes a real-time automated communication method. In the method, a real-time communication session can be established between a text exchange client and a speech application. A translation table can be identified that includes multiple entries, each entry including a text exchange item and a corresponding conversational translation item. A text exchange message can be received that was entered into a text exchange client. Content in the text exchange message that matches a text exchange item in the translation table can be substituted with a corresponding conversational item. The translated text exchange message can be sent as input to a voice server. Output from the voice server can be used by the speech application, which performs an automatic programmatic action based upon the output.

A method and apparatus for training an acoustic model are disclosed. A training corpus is accessed and converted into an initial acoustic model. Scores are calculated for a correct class and competitive classes, respectively, for each token given the initial acoustic model. Also, a sample-adaptive window bandwidth is calculated for each training token. From the calculated scores and the sample-adaptive window bandwidth values, loss values are calculated based on a loss function. The loss function, which may be derived from a Bayesian risk minimization viewpoint, can include a margin value that moves a decision boundary such that token-to-boundary distances for correct tokens that are near the decision boundary are maximized. The margin can either be a fixed margin or can vary monotonically as a function of algorithm iterations. The acoustic model is updated based on the calculated loss values. This process can be repeated until an empirical convergence is met. 1.

Автор: Fritsch Juergen, Mathias Lambert, Yegnanarayanan Girija
Принадлежит: MULTIMODAL TECHNOLOGIES, LLC

A system is provided for training an acoustic model for use in speech recognition. In particular, such a system may be used to perform training based on a spoken audio stream and a non-literal transcript of the spoken audio stream. Such a system may identify text in the non-literal transcript which represents concepts having multiple spoken forms. The system may attempt to identify the actual spoken form in the audio stream which produced the corresponding text in the non-literal transcript, and thereby produce a revised transcript which more accurately represents the spoken audio stream. The revised, and more accurate, transcript may be used to train the acoustic model using discriminative training techniques, thereby producing a better acoustic model than that which would be produced using conventional techniques, which perform training based directly on the original non-literal transcript. 1. In a system including a first document containing at least some information in common with a spoken audio stream , a method comprising steps of:(A) identifying text in the first document representing a concept having a plurality of spoken forms;(B) replacing the identified text with a context-free grammar specifying the plurality of spoken forms of the concept to produce a second document;(C) generating a first language model based on the second document;(D) using the first language model in a speech recognition process to recognize the spoken audio stream and thereby to produce a third document;(E) filtering text from the third document by reference to the second document to produce a filtered document in which text filtered from the third document is marked as unreliable; and (F)(1) applying a first speech recognition process to the spoken audio stream using a set of base acoustic models and a grammar network based on the filtered document to produce a first set of recognition structures;', '(F)(2) applying a second speech recognition process to the spoken audio stream ...
