Patent number: 10856075Abstract: An apparatus including at least one processor and at least one memory including computer program code configured to: when the apparatus is in a voice phone call mode of sound capture, output a signal from a first microphone as a primary speech signal, and select one or more second microphones to output a noise reduction signal, where the apparatus comprises at least two of the second microphones, and where selection of the one or more second microphones is based at least partially upon a determined use of the apparatus being either a handportable or an integrated handsfree use; and/or when the apparatus is in a multi-media mode of sound capture select one or more of the microphones to output audio signals based upon both a determined type of sound capture feature being used by the apparatus and based upon a determined orientation of the apparatus.Type: GrantFiled: December 7, 2017Date of Patent: December 1, 2020Assignee: Nokia Technologies OyInventors: Antti Heikki Tapio Sassi, Jari Petteri Sjoberg, Ari Juhani Koski, Anu Huttunen, Mari Partio, Riitta Niemisto, Jukka Vartiainen, Ville Mikael Myllyla, Jorma Makinen, Tero Takala

Patent number: 10469944Abstract: An apparatus comprising: an input configured to receive at least three microphone audio signals, the at least three microphone audio signals comprising at least two near microphone audio signals generated by at least two near microphones located near to an desired audio source and at least one farmic audio signal generated by a farmic located further from the desired audio source; a first interference canceller module configured to generate a first processed audio signal based on a first selection from the near microphone audio signals; at least one further interference canceller module configured to generate at least one further processed audio signal based on at least one further selection from the at least three microphone audio signals; a comparator configured to determine from the first processed audio signal and the at least one further processed audio signal the audio signal with greater noise suppression.Type: GrantFiled: October 16, 2014Date of Patent: November 5, 2019Assignee: Nokia Technologies OyInventors: Riitta Niemisto, Ville Myllyla

Publication number: 20070078645Abstract: A method for suppressing noise from a digital audio signal, the method comprising: obtaining the digital signal; dividing the digital audio signal into sub-bands of non-uniform frequency division essentially mitigate Bark scale, corresponding sub-band signals having downsampling ratios by which a frame rate of an audio encoder, expressed in a number of samples in each frame, is divisible; calculating coarse estimates of signal levels for the non-uniform sub-bands; calculating smoothed signal level estimates for the non-uniform sub-bands based on the coarse estimates; and combining the processed sub-band signals into a digital output signal.Type: ApplicationFiled: September 30, 2005Publication date: April 5, 2007Inventors: Riitta Niemisto, Jukka Vartiainen

Publication number: 20060053007Abstract: A device comprising a voice activity detector for detecting voice activity in a speech signal using digital data formed on the basis of samples of an audio signal. The voice activity detector comprises a first element adapted to examine whether the signal has a highpass nature. The voice activity detector also comprises a second element adapted to examine the frequency spectrum of the signal. The voice activity detector is adapted to provide an indication of speech when the first element has determined that the signal has a highpass nature or the second element has determined that the signal does not have a flat frequency response.Type: ApplicationFiled: August 29, 2005Publication date: March 9, 2006Inventor: Riitta Niemisto
