摘要： A radio communication system includes a voice recognition system (218), a transmitter (202) and a processing system (210). The voice recognition system is utilized for receiving caller initiated messages, and the transmitter is used for transmitting messages to a plurality of SCRs (selective call radios) (122) of the radio communication system. The processing system, which is coupled to the voice recognition system, and the transmitter, is adapted to cause the voice recognition system to convert a voice signal representative of a voice message originated by a caller of the radio communication system to a text message (401, 417), wherein the text message is intended for a SCR, to then generate a likelihood of success that the voice signal has been flawlessly converted to a text message, to have a human listen to an audible representation of the voice signal, and to cause the transmitter to transmit the text message to the SCR (432). The converting step includes autocorrelation by Fourier transform, measure a degree of voiceness for each band, applying the degree of voiceness to a corresponding plurality of phenome models, and deriving a text equivalent by searching through a phenome library.

摘要： A search system will receive a voice query and use speech recognition with a predefined vocabulary to generate a textual transcription of the voice query. Queries are sent to a text search engine, retrieving multiple web page results for each of these initial text queries. The collection of the keywords is extracted from the resulting web pages and is phonetically indexed to form a voice query dependent and phonetically searchable index database. Finally, a phonetically-based voice search engine is used to search the original voice query against the voice query dependent and phonetically searchable index database to find the keywords and/or key phrases that best match what was originally spoken. The keywords and/or key phrases that best match what was originally spoken are then used as a final text query for a search engine. Search results from the final text query are then presented to the user.

摘要： Disclosed is a method for parsing a verbal expression received from a user to determine whether or not the expression contains a multiple-goal command. Specifically, known techniques are applied to extract terms from the verbal expression. The extracted terms are assigned to categories. If two or more terms are found in the parsed verbal expression that are in associated categories and that do not overlap one another temporally, then the confidence levels of these terms are compared. If the confidence levels are similar, then the terms may be parallel entries in the verbal expression and may represent multiple goals. If a multiple-goal command is found, then the command is either presented to the user for review and possible editing or is executed. If the parsed multiple-goal command is presented to the user for review, then the presentation can be made via any appropriate interface including voice and text interfaces.

摘要： A method and apparatus for generating a query from multimedia content is provided herein. During operation a query generator (101) will receive multi-media content and separate the multi-media content into at least a video portion and an audio portion. A query will be generated based on both the video portion and the audio portion. The query may comprise a single query based on both the video and audio portion, or the query may comprise a “bundle” of queries. The bundle of queries contains at least a query for the video portion, and a query for the audio portion of the multimedia event.

摘要： A method of performing a search of a database of speakers, includes: receiving a query speech sample spoken by a query speaker; deriving a query utterance from the query speech sample; extracting query utterance statistics from the query utterance; performing Kernelized Locality-Sensitive Hashing (KLSH) using a kernel function, the KLSH using as input the query utterance statistics and utterance statistics extracted from a plurality of utterances included in a database of speakers in order to select a subset of the plurality of utterances; and comparing, using an utterance comparison equation, the query utterance statistics to the utterance statistics for each utterance in the subset to generate a list of speakers from the database of utterances having a highest similarity to the query speaker.
