Discriminative data selection for language modeling

11/17/16 - 20160336006 - A computer system for language modeling may collect training data from one or more information sources, generate a spoken corpus containing text of transcribed speech, and generate a typed corpus containing typed text. The computer system may derive feature vectors from the spoken corpus, analyze the typed corpus to determine
Inventors: Michael Levit, Shuangyu Chang, Benoit Dumoulin

Speech recognition error diagnosis

09/01/16 - 20160253989 - Techniques and technologies for diagnosing speech recognition errors are described. In an example implementation, a system for diagnosing speech recognition errors may include an error detection module configured to determine that a speech recognition result is least partially erroneous, and a recognition error diagnostics module. The recognition error diagnostics module
Inventors: Shiun-zu Kuo, Thomas Reutter, Yifan Gong, Mark T. Hanson, Ye Tian, Shuangyu Chang, Jon Hamaker, Qi Miao, Yuancheng Tu

User query history expansion for improving language model adaptation

11/12/15 - 20150325237 - Query history expansion may be provided. Upon receiving a spoken query from a user, an adapted language model may be applied to convert the spoken query to text. The adapted language model may comprise a plurality of queries interpolated from the user's previous queries and queries associated with other users.
Inventors: Shuangyu Chang, Michael Levit, Bruce Melvin Buntschuh

Context specific language model scale factors

11/12/15 - 20150325236 - The customization of recognition of speech utilizing context-specific language model scale factors is provided. Training audio may be received from a source in a training phase. The received training audio may be recognized utilizing acoustic and language models being combined utilizing static scale factors. A comparison may then be made
Inventors: Michael Levit, Shuangyu Chang, Zhiheng Huang

Flexible schema for language model customization

10/01/15 - 20150278191 - The customization of language modeling components for speech recognition is provided. A list of language modeling components may be made available by a computing device. A hint may then be sent to a recognition service provider for combining the multiple language modeling components from the list. The hint may be
Inventors: Michael Levit, Hernan Guelman, Shuangyu Chang, Sarangarajan Parthasarathy, Benoit Dumoulin

Incremental utterance decoder combination for efficient and accurate decoding

09/24/15 - 20150269949 - An incremental speech recognition system. The incremental speech recognition system incrementally decodes a spoken utterance using an additional utterance decoder only when the additional utterance decoder is likely to add significant benefit to the combined result. The available utterance decoders are ordered in a series based on accuracy, performance, diversity,
Inventors: Shuangyu Chang, Michael Levit, Abhik Lahiri, Barlas Oguz, Benoit Dumoulin

Language model adaptation using result selection

12/11/14 - 20140365218 - A received utterance is recognized using different language models. For example, recognition of the utterance is independently performed using a baseline language model (BLM) and using an adapted language model (ALM). A determination is made as to what results from the different language model are more likely to be accurate.
Inventors: Shuangyu Chang, Michael Levit

User query history expansion for improving language model adaptation

03/28/13 - 20130080162 - Query history expansion may be provided. Upon receiving a spoken query from a user, an adapted language model may be applied to convert the spoken query to text. The adapted language model may comprise a plurality of queries interpolated from the user's previous queries and queries associated with other users.
Inventors: Shuangyu Chang, Michael Levit, Bruce Melvin Buntschuh

Automatic semantic evaluation of speech recognition results

03/28/13 - 20130080150 - A semantic error rate calculation may be provided. After receiving a spoken query from a user, the spoken query may be converted to text according to a first speech recognition hypothesis. A plurality of results associated with the converted query may be received and compared to a second plurality of
Inventors: Michael Levit, Shuangyu Chang, Bruce Melvin Buntschuh, Nick Kibre

Dynamically adding personalization features to language models for voice search

12/13/12 - 20120316877 - A dynamic exponential, feature-based, language model is continually adjusted per utterance by a user, based on the user's usage history. This adjustment of the model is done incrementally per user, over a large number of users, each with a unique history. The user history can include previously recognized utterances, text
Inventors: Geoffrey Zweig, Shuangyu Chang

Recognition using re-recognition and statistical classification

12/09/10 - 20100312546 - Architecture that employs an overall grammar as a set of context-specific grammars for recognition of an input, each responsible for a specific context, such as subtask category, geographic region, etc. The grammars together cover the entire domain. Moreover, multiple recognitions can be run in parallel against the same input, where
Inventors: Shuangyu Chang, Michael Levit, Bruce Buntschuh

Utterance processing for network-based speech recognition utilizing a client-side cache

06/24/10 - 20100161328 - Embodiments are provided for utilizing a client-side cache for utterance processing to facilitate network based speech recognition. An utterance comprising a query is received in a client computing device. The query is sent from the client to a network server for results processing. The utterance is processed to determine a
Inventors: Andrew K. Krumel, Shuangyu Chang, Robert L. Chambers

Sequential speech recognition with two unequal asr systems

04/01/10 - 20100082343 - Sequential speech recognition using two unequal automatic speech recognition (ASR) systems may be provided. The system may provide two sets of vocabulary data. A determination may be made as to whether entries in one set of vocabulary data are likely to be confused with entries in the other set of
