Patent number: 7392188Abstract: A system and method enabling acoustic barge-in during a voice prompt in a communication system. An acoustic prompt model is trained to represent the system prompt using the specific speech signal of the prompt. The acoustic prompt model is utilized in a speech recognizer in parallel with the recognizer's active vocabulary words to suppress the echo of the prompt within the recognizer. The speech recognizer may also use a silence model and traditional garbage models such as noise models and out-of-vocabulary word models to reduce the likelihood that noises and out-of-vocabulary words in the user utterance will be mapped erroneously onto active vocabulary words.Type: GrantFiled: July 31, 2003Date of Patent: June 24, 2008Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jochen Junkawitsch, Raymond Bruckner, Klaus Reinhard, Stefan Dobler

Patent number: 7366667Abstract: Method and device for the recognition of words and pauses in a voice signal. The words (Wi) spoken in a row and pauses (Ti) are thereby combined as to be appertaining to a word group as soon as one of the pauses (Ti) exceeds a limit value (TG). Stored references (Rj) are allocated to the voice signal of the word group, and an indication of the result of the allocation is effected after the limit value (TG) has been exceeded. To this end, parameters corresponding to the moments of the transitions between ranges with voice and non-voice are determined from the voice signal, and the limit value (TG) is then changed in dependence on said parameters.Type: GrantFiled: December 21, 2001Date of Patent: April 29, 2008Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Stefan Dobler

Patent number: 6961702Abstract: The invention relates to a method for generating an adapted reference for automatic speech recognition. In a first step, recognition is performed based on a spoken utterance and a recognition result which corresponds to a currently valid reference is obtained. In a second step, the currently valid reference is adapted in accordance with the utterance in order to create an adapted reference. In a third step, the adapted reference is assessed and it is decided if the adapted reference is used for further recognition.Type: GrantFiled: November 6, 2001Date of Patent: November 1, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stefan Dobler, Andreas Kiessling, Ralph Schleifer, Raymond Brückner

Publication number: 20040199388Abstract: The present invention relates to a user interactive user friendly speech recognition controller and method of operating the same. The speech recognition controller recognises (S1, S11, S12, S20, S27) at least one keyword in a speech utterance enunciated by a user and obtain (S2, S7, S13, S24, S40) for said at least one recognized keyword a recognition reliability which indicates how reliably said at least one keyword has been recognized correctly by the speech recognition controller. It then compares (S3, S26, S41) said reliability with a recognition reliability threshold and if said obtained reliability is lower than said recognition reliability threshold, it provides (S4, S14, S32, S35) an unreliability indication to the user (S4, S14, S32). In response to said unreliability indication it recognises at least one further keyword and then corrects said at least one recognized recognized in response to said unreliability indication to the user.Type: ApplicationFiled: April 23, 2004Publication date: October 7, 2004Inventors: Werner Armbruster, Stefan Dobler, Catriona Chaplin

Patent number: 5687288Abstract: Speech recognition produces test signals from the speech signal which are compared with predetermined reference signals so as to form scores. Each subsequent test signal is compared with reference values which are situated within a predetermined neighborhood of the reference value which has been determined to be optimum for the preceding test signal. In dependence on this neighborhood, transition values in conformity with the transition probabilities are added to the scores. In order to enhance the results notably in the case of different speeds of speaking of the instantaneous speaker, it is proposed to adapt these transition values in dependence on the speed of speaking. A further improvement can be achieved by also adapting the reference values themselves to the relevant speaker's pronunciation. This adaptation can also be iteratively performed in a number of steps.Type: GrantFiled: September 14, 1995Date of Patent: November 11, 1997Assignee: U.S. Philips CorporationInventors: Stefan Dobler, Hans-Wilhelm Ruhl
