Patent number: 9843880Abstract: A system enhances spatialization in which spatial information about sound sources at an originating location is represented in an audio signal. The system applies a phase difference analysis to the signals received from an array of spaced apart input devices or microphones to derive spatial or directional information about the relative directions of one or more satellite input devices or microphones. The signals from the satellite input devices or microphones are mixed by a function of their respective directions to generate a multichannel output signal. When processed by a remote or local system, the output signal provides a representation of the relative directions of the sound sources at the originating location at a receiving location.Type: GrantFiled: December 16, 2014Date of Patent: December 12, 2017Assignee: 2236008 Ontario Inc.Inventors: Phillip A. Hetherington, Mark Fallat

Patent number: 9736611Abstract: A system enhances spatialization in an audio signal at a receiving location. The system applies a phase difference analysis to signals received from an array of spaced apart input devices that convert sound into electrical signals. The system derives spatial or directional information about the relative locations of the sound sources. The converted signals may be mixed using weights derived from the spatial information to generate a multichannel output signal that, when processed by a remote or local audio system, generates a representation of the relative locations of the sound sources at the originating location at the receiving location.Type: GrantFiled: April 17, 2015Date of Patent: August 15, 2017Assignee: 2236008 Ontario Inc.Inventors: Phillip A.

Patent number: 8438022Abstract: A system improves speech detection or processing by identifying registration signals. The system encodes a limited frequency band by varying the amplitude of a pulse width modulated signal between predefined values. The signal is separated into frequency bins that identify amplitude and phase. The registration signal is measured by comparing a difference in average acoustic power in a plurality of adjacent bins over time.Type: GrantFiled: April 11, 2012Date of Patent: May 7, 2013Assignee: QNX Software Systems LimitedInventors: Mark Fallat, Derek Sahota

Patent number: 8311819Abstract: A system detects a speech segment that may include unvoiced, fully voiced, or mixed voice content. The system includes a digital converter that converts a time-varying input signal into a digital-domain signal. A window function passes signals within a programmed aural frequency range while substantially blocking signals above and below the programmed aural frequency range when multiplied by an output of the digital converter. A frequency converter converts the signals passing within the programmed aural frequency range into a plurality of frequency bins. A background voice detector estimates the strength of a background speech segment relative to the noise of selected portions of the aural spectrum. A noise estimator estimates a maximum distribution of noise to an average of an acoustic noise power of some of the plurality of frequency bins.Type: GrantFiled: March 26, 2008Date of Patent: November 13, 2012Assignee: QNX Software Systems LimitedInventors: Phillip A.

Patent number: 8244538Abstract: A system evaluates a hands free communication system. The system automatically selects a consonant-vowel-consonant (CVC), vowel-consonant-vowel (VCV), or other combination of sounds from an intelligent database. The selection is transmitted with another communication stream that temporally overlaps the selection. The quality of the communication system is evaluated through an automatic speech recognition engine. The evaluation occurs at a location remote from the transmitted selection.Type: GrantFiled: April 29, 2009Date of Patent: August 14, 2012Assignee: QNX Software Systems LimitedInventors: Shreyas Paranjpe, Mark Fallat

Patent number: 8165880Abstract: An end-pointer determines a beginning and an end of a speech segment. The end-pointer includes a voice triggering module that identifies a portion of an audio stream that has an audio speech segment. A rule module communicates with the voice triggering module. The rule module includes a plurality of rules used to analyze a part of the audio stream to detect a beginning and an end of the audio speech segment. A consonant detector detects occurrences of a high frequency consonant in the portion of the audio stream.Type: GrantFiled: May 18, 2007Date of Patent: April 24, 2012Assignee: QNX Software Systems LimitedInventors: Phillip A.
