Patent number: 7630878Abstract: Speaker-dependent speech recognition is performed upon detecting a speech signal encompassing a voice command. The speech signal is divided into time frames and characterized in each detected time frame by forming a corresponding property vector. A language-independent feature vector sequence is formed from one or several property vectors and then stored. The language-independent feature vector sequence is allocated to a language-dependent sequence of model vectors in a speech resource having a plurality of model vectors. A piece of allocation information indicating allocation of the language-independent feature vector sequence to a language-dependent sequence of model vectors is stored, then the voice command allocated to the model vector sequence is identified.Type: GrantFiled: May 4, 2004Date of Patent: December 8, 2009Assignee: SVOX AGInventors: Tim Fingscheidt, Sorel Stan

Publication number: 20080228477Abstract: A speech signal is processed for subsequent speech recognition. The speech signal is tainted by noise and represents at least one speech command. The following steps are executed: a) recording of the noise-tainted speech signal; b) use of noise reduction on the speech signal to generate a noise-reduced speech signal; c) normalization of the noise-reduced speech signal to a target signal value with the aid of a normalization factor, to generate a noise-reduced, normalized speech signal).Type: ApplicationFiled: October 4, 2004Publication date: September 18, 2008Inventors: Tim Fingscheidt, Panji Setiawan, Sorel Stan

Publication number: 20060160581Abstract: Disclosed is a method for suppressing (10) echo (z(t)) in uplink data (y(t), 12-16) originating from a terminal (2, 3), said method allowing a delay and a decrease in quality during echo suppression of uplink data originating from a wireless terminal (2, 3). According to the inventive method, original or copied downlink data (12-16) and uplink data (19-21) are analyzed in order to prepare echo suppression (10), and uplink data (19-21) is modified in the compressed state in order to reduce echo (10) by using the results of said analysis (9) of the downlink data (12-16) and uplink data (19-21).Type: ApplicationFiled: December 20, 2002Publication date: July 20, 2006Inventors: Christopher Beaugeant, Renato Beluffi, Tim Fingscheidt, Herbert Heib, Bernd Jager, Luca Prati, Herve Taddei

Publication number: 20040148162Abstract: The invention relates to a method for encoding voice signals, especially so-called voice onset sections. By establishing the first amplification factor, the data quantity for representing the whole of the first or adaptive amplification factor and adaptive code book entry is reduced, whereby other parameters which occur during the voice encoding can be represented in a more precise manner. The invention also relates to a method for transmitting voice signals which are encoded in such a way.Type: ApplicationFiled: November 18, 2003Publication date: July 29, 2004Inventors: Tim Fingscheidt, Herve Taddei, Imre Varga
